Common
Skincare Terms

Below you will find some commonly used terminology in skincare.

Active ingredients
Substances in cosmetic formulations that introduce an additional beneficial effect to the cream. Active substances can for example have an anti-wrinkling or soothing effect on the skin.

Antioxidant
A substance that prevents other molecules from oxidation. Thus, it works like an anti-rust agent in the body.

Avena Sativa Kernel Extract
Extract from oats. Antioxidant with anti-histamine properties.

Ceramide
Essential skin lipid

Curcumine
Extract from turmeric. Strong antioxidant. The word is used here as a short form for tetrahydrocurcumine (see below).

Dermis
Deeper skin layer.

Epidermis
The outermost layer of the skin.

Extrinsic ageing
Ageing caused by external factors such as sun and smoking (see intrinsic ageing).

Erythema
Skin redness.

Ex vivo
Test on living cells outside of the organism (body) such as on cultured cells (see in vivo and in vitro).

Free radical
A substance that causes oxidation of molecules. Simply put, it makes the body “rust”.

Hyperpigmentation
Darkened area of skin.

Intrinsic ageing
Ageing caused by inherited genetic factors (see extrinsic ageing).

In vitro
Test using test tubes.

In vivo
Test on whole, living organisms. Here: test on humans.

Lipids
Fat-soluble substances such as oils, waxes and cholesterol.

Melasma
Darker areas or spots on skin, often on chin, forehead, nose and lip.

Micro formulation
A cream or lotion where all particles are micro sized. Thereby the cream will better spread on the skin surface with improved absorption of active ingredients.

Nano
A prefix indicating that something is a billionth, such as nanometer, nanosecond etc.

Nano particles
Extremely small particles, gaining in popularity in science. Nano particles are sometimes used in skincare. However, due to the small size, many scientists suspect the particles might penetrate through the skin and to other body organs where they might cause damage. Verso Skincare does not contain nano particles.

Niacinamide
Vitamin B3. Essential substance for the generation of energy in cells. Has a brightening effect on skin.

Peptides
Parts of amino acids. Have varying functions in skincare depending on the peptide (see Acetyl Tetrapeptide-5).

Piperine
Pepper extract, improves absorption of actives into the skin.

Retinyl retinoate
A form of Vitamin A, 8 times more effective than retinol. In skincare, retinol has been proven to reduce pigment spots, decrease fine lines and wrinkles and to improve skin elasticity.

Skin barrier
The uppermost layer of the skin consisting of flattened skin cells together with layered lipids and humectants. The skin barrier is very protective, preventing harmful substances from entering the body.

Stratum corneum
The uppermost part of the skin (the part of the skin that is visible to the eye) that consists of dead flattened skin cells.

Tetrahydrocurcumine
Extract from turmeric. The colourless metabolite from curcumin (see above). Strong antioxidant.

TWL
Trans-epidermal water loss. Moisture lost from skin and body through normal evaporation.
A high value indicates dry skin and a malfunctioning skin barrier (see skin barrier).

Tyrosinase
An enzyme that take part in the formation of melanin.

UVA
Ultra violet light with a wave length of 320-400 nm (nanometers, see nano). Exaggerated exposure is thought to cause skin cancer. Does not produce typical sunburn.

UVB
Ultra violet light with a wave length of 290-320 (nanometers, see nano). UVB exposure results in the typical sunburn.
