A

Acne

From mildly annoying blackheads and whiteheads to huge, painful pimples that seem to sprout up on the worst days, acne is a type of skin inflammation. It can be caused by oil imbalance, dead skin cell build-up, and slower skin cell turnover associated with ageing. 

Acetone

A colourless organic chemical used in nail polish remover. It works by softening and dissolving polymer molecules in polishes, gels, and acrylics.

Acid Mantle

Used to describe the acidic nature of the skin’s surface, acid mantle is a very thin film coating the skin that acts as a barricade against bacteria, viruses, and other potential contaminants. Acid mantle is created by sweat mingling with the sebum secreted by the sebaceous glands.

Active Ingredients

Active ingredients or “actives” in skincare products are, simply put, the chemicals or molecules doing what the product says it’s supposed to do. For example, zinc oxide is the active ingredient for boosting SPF, hyaluronic acid for combating skin dryness, and azelaic acid for treating rosacea.

Acupressure

Originating from Traditional Chinese Medicine theories of invisible lines on the body that carry energy called “qi”, acupressure uses specific points along these meridians to help restore balance to cure various ailments. Benefits also include reduced muscle tension and improved blood circulation.

Acupuncture

A traditional Chinese medical procedure that involves stimulating certain points on the body with tiny needles to restore balance. This is believed to alleviate pain and nausea or help treat various health conditions.

Adenosine

A yeast-derived skincare ingredient that has strong anti-aging properties. Applied topically, it aids in the production of dermal fibroblasts (e.g. collagen and elastin) to improve and rejuvenate dull and sagging skin.

Allantoin

A naturally derived additive found in skincare products, extracted from plants such as beets and chamomile. Allantoin helps skin retain moisture for longer and fights issues such as dry and scaly skin. 

Age Spots

Also called sunspots, freckles, and liver spots, age spots are flat brown, black or yellow skin discolorations that occur most commonly on the hands, neck, and face. The primary cause is sun exposure. 

Ageing

The process of becoming older, reflecting on the skin via changes caused by additional factors such as stress, gravity, sleep position, and daily facial movements.

Alpha Hydroxy Acids (AHA)

Alpha Hydroxy Acids (AHA’s) are a group of plant and animal-derived acids that are used in skincare products. They are considered chemical exfoliants for using chemicals (acids/enzymes) to slough away dead surface skin cells. 

Amino Acid

Amino acids are the building blocks of peptides and are found commonly in skincare products. They help to hydrate, replenish, and promote cellular repair in the skin.

Ammonia

Ammonium chloride is a popular form of ammonia that is used in shampoos, hair dyes, hand soap and body wash to create a thicker lather. Use should be subject to skin sensitivity.

Anagen

The first phase of the hair growth cycle when the root of the hair divides at a rapid rate, averaging 1cm of physical growth per month. This active phase can last anywhere between 2 and 7 years.

Ampoule

Skincare products that come in plastic or glass vials that are broken open right before use. The easily portable vials contain high-potency serums to quickly boost skin wherever, whenever.

Anti-ageing

A product or technique designed to slow, prevent, or reverse the signs or appearance of getting older.

Anthocyanins

Red, blue and violet plant pigments that are thought to prevent against inflammatory disease and free radical damage. Studies have shown anthocyanins play a key role in the body by fortifying blood vessel walls to improve blood flow.

Antioxidants

Antioxidants are molecules that protect cells against damage (aka “oxidative stress”) from free radicals. For example, lemon juice (containing the antioxidant Vitamin C) squeezed over an apple slice will prevent it from turning brown. The same can work on skin, including a cocktail of Vitamins A, C, and E to prevent damage and repair skin cells.

Argan Oil

A fast-absorbing Vitamin E extract that moisturizes without clogging pores. Other benefits include reducing the appearance of fine lines, smoothening hair, and strengthening nails.

Arginine

A synthetic version of this wound-healing amino acid is typically found in topical skincare products that combat fine lines and wrinkles caused by ageing. Considered a critical building block of skin collagen and hair keratin.

Ascorbic Acid

Also known as l-ascorbic acid, this topical form of antioxidant Vitamin C brightens skin, increases collagen production, and stems free-radical damage.

Aqua Facial

Also known as Aqua Peel, Aqua Facial is a treatment that uses a water-based gel for deep-pore cleansing and exfoliation, and a suction device that removes impurities whilst simultaneously flooding the skin with moisture. A gentler alternative to chemical exfoliants for visibly younger-looking skin.

Avobenzone

A common broad-spectrum chemical sunscreen that protects from sunburn-causing UVB rays and premature skin aging-causing UVA rays. Avobenzone works by absorbing harmful UV radiation, and is a common ingredient in sunscreen.

B

BB Cream

BB refers to “Beauty Balm” or “Blemish Balm”, a supercharged foundation concept originally created by dermatologists in Germany and Korea. The advertised “5-in-1” benefits include moisturizing dry and dehydrated skin, camouflaging uneven skin tones and blemishes, priming the skin by filling in uneven textures and pores, and providing SPF sun protection.

Beta-Hydroxy Acid (BHA)

BHA works to control excess oil production and reduce the amount of pore-clogging sebum that contributes to breakouts, whilst simultaneously working to exfoliate the skin surface. One of the most common BHA’s, Salicylic Acid is found in many acne washes, creams, and peels.

Biocellulose

Popular and biodegradable material for sheet mask, with fibres derived from bacteria. Provides a snug fit and boasts unparalleled moisture retention, which helps to better soak active ingredients into the skin. 

Biotin

Blackhead (Comodo)

An ‘open-air’ skin blemish that forms when sebum draining from a pore becomes blocked by dead skin cells at the surface. The black colour results from the sebum pigment, which darkens when exposed to air.

Blind Acne

Acne that develops under the skin surface deep within a pore, typically of the cystic variety that rarely comes to a head.

Botox

Trademark name for a form of botulinum toxin used in injections to target facial wrinkles. Botox paralyzes facial muscles to reduce the appearance of wrinkles, such as crow’s feet.

Bruise

A discoloration of skin caused by capillaries being damaged by trauma. This causes blood to be released and collect near the surface of the skin.

C

Caffeine

The chief stimulant in beverages such as coffee, caffeine is also commonly used in anti-aging skincare for its antioxidant properties. Due to its ability to constrict blood vessels, caffeine is commonly used in cellulite creams and eye creams to reduce redness and puffiness.

Cannabidiol (CBD)

A naturally occurring chemical in the Cannabis sativa plant (aka marijuana), CBD is effective for combating skin aging. Available in serums, balms, lotions, and oils, CBD is a powerful antioxidant that supports healthy skin. It cannot produce a high.

Carbon Dioxide Laser

Also known as CO2 laser, it is commonly used to perform fractional skin resurfacing treatments. Healing time requires around 1-2 weeks.

CC Cream

The CC stands for “Color Correcting” and is similar to BB cream, but with additional anti-aging, spot-reducing and tone-balancing properties. 

Cell Communication

A broad term referring to the way proteins send signals to the body’s immune system to send new skin cells to a wound in the process of cell turnover. With aging, disruptions to communication between skin cells slow down the migration of skin cells.

Cellulite

Affecting up to 90% of women, cellulite occurs when fat cells swell and push through tight, fibrous tissue bands, creating a dimpled or lumpy appearance on the skin. This may be caused by poor lymphatic drainage, fluid retention, poor circulation, not drinking enough water, and simple genetics.

Ceramides

Naturally occurring in sebum, ceramides are waxy lipid molecules (aka fats) that hold together the cells of the epidermis to reinforce the skin’s protective barrier. They make up about 50% of the outer layer of skin.

Coenzyme Q10 (Ubiquinone)

An antioxidant produced naturally by the body for growth and maintenance. Levels of CoQ10 in skin go down with age and UV exposure, and is used in skincare products to preserve skin cell function.

Chemical Peel

A skin-resurfacing treatment technique used to improve and smooth texture of skin. Used to treat wrinkles, skin discoloration, and scars by removing the top layers of skin.

Chemical Sunscreen

A sunscreen that is formulated using chemical compounds that penetrate in the skin to absorb UV rays, which are converted into heat and then released from the body. Requires 20 minutes to absorb after application.

Clean Beauty

Cosmetic and skincare products that use sustainably sourced ingredients in recyclable or biodegradable packaging. Rejects ingredients considered toxic such as parabens, sulfates, phthalates, and more.

Collagen

A “skin building block” protein that makes up roughly 80% of skin. Collagen fibres give skin its strength and firmness. Laser treatments and retinoids build it up, while UV rays and free radicals tear it down.

Combination Skin

A skin type that features two or more different skin characteristics, depending on the number of sebaceous glands on each area of the face. For example, combination skin can be part dry, part oily, and part normal.

Comedones

Cream

Thicker than serums or lotions, creams are a mixture of oil and water. Creams tend to have a higher concentration of oil, which causes the thicker consistency. 

Cystic Acne

The most serious type of acne, caused by a combination of bacteria, oil, and dry skin cells that get trapped deep within the skin tissue. This leads to infection and inflammation, which usually cannot be treated with over-the-counter acne medication and would require oral antibiotics.

D

Dandruff

A harmless scalp condition that causes white-yellow scaly flakes of skin to appear in the hair, caused by excessive skin cell production. 

Dermatitis

Atopic dermatitis is also known as eczema. Contact dermatitis is an inflammation of the skin caused by direct contact with an irritating substance.

Dermis

The thickest and deepest layer of the skin underlying the epidermis. This is where blood vessels, nerve endings, sweat glands, sebaceous glands, fat cells, hair follicles and muscles are located.

Double Cleanse

A Korean beauty ritual of using a cleansing oil in tandem with a water-based face wash to thoroughly dissolve and remove oil-based makeup, sunscreen, and other pollutants that have collected on the skin.

Dry Brushing

The process of exfoliating dead skin cells on the body using a firm brush with natural bristles. The technique originates from 5000-year-old Ayurvedic medicine, a popular treatment that improves circulation, reduces the appearance of cellulite, reduces swelling, and relieves tension.

Dry Shampoo

A starch or silica-based powder or aerosol formula that soaks up excess oil between hair washes. Also works as a texturizing and volumizing agent when hair styling.

Dry Skin

A common skin condition characterized by lack of hydration in the epidermis. Dry skin may often feel ‘tight’ or uncomfortably stretched after cleansing, so creamy cleansers and cleansing oils are recommended, in addition to drinking plenty of water.

Dysport

Like Botox, Dysport is another injectable form of the botulinum toxin that paralyzes wrinkles to combat fine lines and wrinkles.

E

Eczema

A chronic, non-contagious disorder of the skin. The most common form of eczema is atopic dermatitis, which is characterized by itchy, red, and scaly patches that often show up on the inner elbows, behind the knees, and around the neck and eyes. Flare-ups may occur with exposure to harsh soaps, fragrances, and foods that provoke an allergic response.

Elastin

Like collagen, elastin is a protein that can be found within the skin’s connective tissues. Formed of peptides, fibroblasts, and amino acids, elastins are responsible for the skin’s elasticity and ability to ‘bounce back’. Sun exposure causes the most damage to the network of elastin fibers over time, making sunscreen important in the protection of skin elasticity.

Elixir

In skincare, elixirs are a potent combination of various oils that help to prevent fine lines. Typically, they contain herbal ingrains, plant extracts, and high concentrations of active ingredients such as hyaluronic acid.

Emollient

Any ingredient that increases water levels in the epidermis. Synonym: moisturizer.

A non-permanent way to add youthful plumpness to the lips, minimize wrinkles and scars, smooth under-eye hollows, contour cheeks, temples, noses, and jaw lines.

Fine Lines

One of the earliest signs of aging, fine lines are less than 2 milometers deep and can develop over time into deeper folds and wrinkles. Causes may include repetitive facial movements and smoking.

Fractional Laser

Developed in 2001 to deliver skin resurfacing results with less downtime than a traditional CO2 laser, fractional devices apply small columns of thermal injury to the skin. After healing, patients tend to see improvements in skin tone and texture.

Freckles

Small brown spots that are caused by an overproduction of melanin, typically in areas of the skin with the most sun exposure.

Free Radicals

Highly unstable molecules created in the body by sunlight, cigarette smoke, and pollution that latch onto and damage cells. Free radicals reduce the skin’s natural rejuvenating abilities, leading to roughness, sagging, and wrinkling. Antioxidants protect against free-radical activity by reinforcing the skin’s defences.

G

Pimples

A type of comedo that occurs due to a combination of excess sebum, bacteria and trapped dead skin cells in the pores. Synonym: acne.

Plant Stem Cells

Stem cells are a group of undifferentiated cells that act as the source of new cells to grow or replace specialised tissues. Not only are plants able to regenerate damaged tissue, but they are also able to develop new plants altogether (e.g. cutting off the branch of a tree results in the growth of a new branch). Little evidence supports the claim that these same regenerating effects translate to human skin when plant cells are extracted and applied topically via skincare products.

Plasma

A minimally invasive method of skin regeneration that uses plasma energy to improve signs of aging such as fine lines, wrinkles, and dark spots. The skin is also charged with high amounts of energy so it is able to absorb water soluble skincare products more easily.

Pore

Small openings in the skin surface. Salts left behind by sweat, along with trapped oil, bacteria and dead skin can clog pores and cause skin conditions such as acne.

Skincare products that reflect the sun’s rays, rather than absorb them. A good choice for those who are more sensitive to chemicals. See: Physical Sunscreen.

Sunscreen

Skincare products with ingredients that absorb, rather than block, UVA and UVB radiation. For the best protection, find a sunscreen labelled broad-spectrum.

T

Tan

Melanocytes in the outermost layer of skin produce pigments to block UV radiation from damaging cells, giving the appearance of darker-coloured skin (AKA a tan).

Text Neck

Neck wrinkles that form from prolonged craning of the neck over screens and devices.

Trichloroacetic Acid (TCA)

The key ingredient in chemical peels for treating sun damage and hyperpigmentation. TCA peels promote shedding of the outermost layer of dead skin cells to allow new cells to rise to the surface.

Thermage

A US FDA-approved anti-aging treatment, Thermage is a technology that uses a radio-wave device to tighten skin and reduce the appearance of wrinkles.

Titanium Dioxide

A natural mineral used as a physical sunscreen to protect against both UVA and UVB, giving it the broad-spectrum label.

Toner

Applied after cleansing, liquid toners balance the skin’s pH, removes excess dirt or oils, and helps subsequent skincare products penetrate the skin more easily.

Turkey Neck

A term for wrinkled, sagging neck skin. It occurs when the skin loses its elasticity, caused by the natural process of aging and environmental stressors such as sun damage.

T-Zone

The area of the face that includes the forehead, nose, chin, and sometimes the neck.

U

Ulthera

A non-invasive FDA-cleared treatment that uses ultrasound energy to lift and tighten the skin, by stimulating the body’s natural process of collagen production.

UVA

The wavelength of ultraviolet light that is associated with signs of aging. It destroys existing collagen and elastin as well as the body’s ability to produce more. UVA is the main reason for skin damage associated with photoaging. 

UVB

The wavelength of ultraviolet light that reaches the top layer of skin, and the main cause of sunburns. Short-wave UVB is also the chief culprit of tanning, freckles, and age spots, and is strongest in summer months.

UVA/UVB

The two types of rays from sunlight that reach the earth. Both are responsible for skin damage, while UVA is known to penetrate deeper into the skin to cause long-term damage such as wrinkles. Both can cause skin cancer.

U-Zone

The area of the face that includes the temples, cheeks, and chin. While the T-zone is associated with high sebum secretion, the U-zone is considered the opposite with low sebum in combination skin.

V

Vampire Facial (AKA Platelet-Rich Plasma [PRP])

A skin treatment that uses the patient’s own blood to trick the body into triggering a wound-healing response. Blood is extracted then placed in a centrifuge, after which it is injected into or applied topically on the patient’s skin to promote cell renewal.

Vitamin C

A water-soluble vitamin with a wealth of antioxidant benefits in skincare. In addition to neutralizing free radicals, vit C is proven to fade hyperpigmentation for a skin brightening effect. Synonym: Ascorbic Acid.

Vitamin D

Naturally produced in the body when exposed to UVB rays, vitamin D can be used as a topical skincare treatment to relieve symptoms of skin conditions such as psoriasis. It can also support elasticity and skin resilience.

Vitamin K

Part of a group of vitamins that are primarily used to help heal wounds, Vitamin K is needed in the body for blood clotting. In skincare, it is used to reduce visible redness and combat dark circles under the eyes.

W

White Hair

Hair that has no pigment. Causes can range from genetics to a Vitamin B deficiency.

Witch Hazel

A plant whose leaves, bark and twigs are used to make medicine. It is believed to have soothing and anti-inflammation benefits, while minimizing visible pores and reducing excess oils on the skin.

Wrinkles

A fold, crease, or ridge that appears as a result of the natural aging process, sun damage, smoking, habitual facial movements, and other factors. Synonym: Rhytide.

X

Xeomin

An FDA-approved neurotoxin (similar to Botox) that is injected into the muscles to improve the appearance of modern to severe frown lines. It is said to be less likely than Botox to cause irritation and allergic reactions due to its purer form of the botulinum toxin.

Z

Zinc Oxide

Considered the best and safest sunscreen ingredient. Not only does Zinc Oxide block both UVA and UVB rays for broad spectrum protection, it is also photostable and resistant to water.

Zits

A slang term for spots or pimples, zits are small and inflamed blemishes on the skin that are typically filled with pus. Synonym: Pimples.
