Ingredients explained

Propylene Glycol
Est. %40
Function
Origin
A clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
Dimethicone
Est. %22
Function
Origin
The most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Glycerin
Est. %11
Function
Origin
The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective. Glycerin also has soothing and anti-irritant properties and is considered to be very safe for use.
Ascorbic Acid
Est. %10.5
Function
Origin
Also known as vitamin C, this extremely well-researched antioxidant is able to boost collagen production, prevent wrinkles, and treat pigmentation. It degrades easily when exposed to air and so requires careful packaging.
Ethylhexyl Palmitate
Est. %4
Function
Origin
A rich emollient without the oily after-feel, making it a popular replacement for mineral oil. It is derived from natural sources such as palm oil and palm kernel oil. Ethylhexyl palmitate is listed as a common comedogenic ingredient by acne.org.
Cetyl PEG/PPG-10/1 Dimethicone
Est. %3
Function
Origin
A silicone-based powerful emulsifier that helps to create lightweight and pleasant feeling lotions and creams.
Dimethicone Crosspolymer
Est. %2.1
Function
Origin
A group of ingredients that are typically added to skincare products to adjust the formula. Dimethicone Crosspolymers stabilize a formula, regulate its thickness and consistency and give the product a velvety feel.
Ascorbyl Glucoside
Est. %2
Function
Origin
A derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.
Cyclohexasiloxane
Est. %1
Function
Origin
A clear silicone fluid with very low viscosity that is commonly used as a solvent and emollient. It has excellent spreadability, rubs in quickly, and leaves a silky smooth after-feel on the skin.
Adenosine
Est. %0.3
Function
Origin
A skin-identical ingredient that is a key molecule in the life of all living cells responsible for energy transportation, signaling, enzyme activity, and much more. In skincare, Adenosine has been found to be an effective anti-wrinkle ingredient.
Citral
Est. %0.3
Function
Origin
A fragrant compound found in many essential oils (especially lemon myrtle and lemongrass essential oil). It has a sweet, lemon-like scent. People with sensitive skin should try to avoid products with citral, or at least do a patch test before using.
Lauroyl Lysine
Est. %0.3
Function
Origin
A synthetic insoluble powder that improves the texture of a product, leaving the skin silky smooth and absorbing oils and sweat.
Hydroxyethylpiperazine Ethane Sulfonic Acid

Limonene
Est. %0.3
Function
Origin

Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate
Est. %0.3
Function
Origin
An antioxidant that protects vulnerable ingredients from the damage caused by ultraviolet radiation, which can also lead to the generation of damaging free radical species.
Isobutane
Est. %0.3
Function
Origin
A compressed gas used in aerosol cans to help expel and foam skin care products.
Polysilicone-11
Est. %0.3
Function
Origin
A synthetic rubber-like substance of the silicone family that has no color or distinct scent. These are large molecules that cannot penetrate the skin but instead create a thin silky film on the skin's surface.
Hydrolyzed Hyaluronic Acid
Est. %0.3
Function
Origin
A smaller-molecule version of the regular hyaluronic acid. It is a powerful humectant that absorbs into the skin and offers moisturizing, smoothing, and anti-wrinkle effects. It is also slightly anti-inflammatory and displays subtle antioxidant properties.

Function
Origin
A fragrant essential oil extracted from the rind or peel of a lemon. It is mainly comprised of limonene (up to 70%) and has a fresh, citrusy scent. Lemon peel oil may cause a sun-induced skin rash in people with a sensitivity towards citrus fruits.
