Ingredients explained

Dimethicone
Est. %40
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.
Isododecane
Est. %22
Function
Origin
An emollient derived from petroleum with high spreadability. It is often used as a replacement for oils and silicones because it leaves no residue behind on the skin. When a product is labeled as “oil-free” it may contain isododecane instead of heavier oils.
Stearoxymethicone/Dimethicone Copolymer
Est. %11
Function
Origin
Description is coming soon
Isononyl Isononanoate
Est. %6
Function
Origin
An ester of a branched fatty acid with a branched fatty alcohol. It is an easily spreadable emollient that has a silky, dry, non-greasy feel on the skin.
Polymethylsilsesquioxane
Est. %4
Function
Origin
A type of spherical powder that functions on a ball-bearing effect in which the tiny microspheres roll around on the skin and create lubricity. Polymethylsilsesquioxane offers extra slip to skincare products and makes the skin feel soft and smooth.
Silica
Est. %3
Function
Origin
A widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Polysilicone-11
Est. %2
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.
Water
Est. %1.5
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Methyl Methacrylate Crosspolymer
Est. %1
Function
Origin
A synthetic ingredient that is used for bulking, film-forming, and controlling viscosity. It can absorb large amounts of water and oil and creates a network for other ingredients to live in.
Mica
Est. %0.3
Function
Origin
A mineral powder made up of silicates with several functions (the main one being as a colorant). It has a shimmery appearance, making it highly desirable in certain cosmetic products. Mica also helps the product to apply more smoothly.
Palmitoyl Tetrapeptide-7
Est. %0.3
Function
Origin
A synthetic peptide that mimics the activity of immunoglobulin G and signals to the skin to stop the inflammation. It has been shown in studies to reduce wrinkles and enhance collagen content.
Palmitoyl Oligopeptide
Est. %0.3
Function
Origin
This is an old INCI name that can refer to several other peptides. They are all short fragments of collagen or elastin and function as signal molecules, telling the skin to repair and restructure the dermis, resulting in anti-wrinkle activity.
Hydrolyzed Collagen
Est. %0.3
Function
Origin
A humectant, film-forming, and emollient mixture of various proteins and peptides that were created by cutting the huge molecules of normal collagen into smaller pieces for better absorption. It also has some antioxidant properties.
Biotin
Est. %0.3
Function
Origin
Biotin is an important nutrient that can cause weak hair and nails if deficient. Unfortunately, while biotin supplements have promising studies, topical biotin in creams and serums doesn’t have a large body of evidence to support its use.
Chrysin
Est. %0.3
Function
Origin
Chrysin is thought to help promote blood circulation in blends with other ingredients and allegedly can help to reduce the appearance of dark under-eye circles. However, no official studies have been done to confirm this.
Arnica Montana Flower Extract
Est. %0.3
Function
Origin
An extract derived from the flower heads of the mountain arnica plant. This plant is used as herbal medicine to treat wounds, bruises, and inflammation. In skincare, however, it is mostly added for fragrance purposes due to its pleasant pine and sage odor.
Coffea Arabica (Coffee) Seed Extract
Est. %0.3
Function
Origin
An antioxidant and emollient extract derived from coffee beans. It has been proven to improve collagen and elastin production in the skin. A small clinical study tested the anti-aging effects of coffee berry extract, and the results were very promising.
Caffeine
Est. %0.3
Function
Origin
An antioxidant compound that is obtained from coffee and tea leaves. It increases the microcirculation of blood in the skin and is claimed to be able to reduce the appearance of orange peel skin (although the research is lacking).
Tocopherol
Est. %0.3
Function
Origin
Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.
Caesalpinia Spinosa Fruit Extract
Est. %0.3
Function
Origin
A powerful astringent ingredient extracted from Tara seed pods. It also has antioxidant benefits.
Kappaphycus Alvarezii Extract
Est. %0.3
Function
Origin
An emollient extract obtained from the red marine algae called elkhorn sea moss. It is a good source of moisturizing and antioxidant carrageenan, a seaweed polysaccharide.
Diamond Powder
Est. %0.3
Function
Origin
A synthetically produced luxury ingredient that has both light-scattering and exfoliating properties.
Glycine Soja (Soybean) Oil
Est. %0.3
Function

Phospholipids
Est. %0.3
Function
Origin
A large group of lipids that are an essential component of every single cell membrane in the body. They have excellent emollient properties. Phospholipids are also utilized in the manufacturing of ‘fancy’ formulations such as liposomes.

Chlorhexidine Digluconate
Est. %0.3
Function
Origin
A synthetic antimicrobial ingredient used to deal with bacterial and fungal skin infections. In the same way that it wipes out bacteria from the skin, it can also fight them inside cosmetic products, acting as a preservative.
