Ingredients explained

Water
Est. %70
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.
Mineral Oil
Est. %9
Function
Origin
Also known as liquid paraffin, it is an amazing moisturizer (the second most occlusive one after Petrolatum). It is also an excellent emollient that fills the micro-cracks on the surface of the skin, making it appear smoother. Mineral oil is considered safe.
Propylene Glycol
Est. %6
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.
PEG-100 Stearate
Est. %4
Function
Origin
This surfactant is more specifically classified as an emulsifier that produces oil-in-water emulsions. PEG-100 stearate can also be used as a cleansing agent.
Glyceryl Stearate
Est. %3
Function
Origin
An emollient and emulsifier typically derived from vegetable sources through a chemical reaction with glycerin. It provides stability, texture, and consistency to formulations. Its main function is to allow oil and water to mix.
Stearic Acid
Est. %2.5
Function
Origin
A saturated fatty acid found in vegetable butter and animal fats. It is an occlusive moisturizing and emollient ingredient and also helps to maintain the barrier function of the skin.
Phenoxyethanol
Est. %1
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Carthamus Tinctorius (Safflower) Seed Oil
Est. %1
Function
Origin
A fatty oil pressed from safflower seeds that is used as an occlusive moisturizer and emollient. It contains unusually high amounts of linoleic acid (up to 70%), as well as antioxidant compounds such as vitamin E, phytosterols, and phenolics.
Triethanolamine
Est. %1
Function
Origin
A clear, colorless, and highly viscous liquid, this ingredient is an excellent pH adjuster. When it is necessary to neutralize an acidic solution or to generally increase the pH of a product, triethanolamine is a common choice.
Carbomer
Est. %1
Function
Origin
A synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Dimethicone
Est. %0.3
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.
Cetyl Alcohol
Est. %0.3
Function
Origin
A waxy solid fatty alcohol derived from palm oil. It is most commonly used as a co-emulsifier and affects the final aesthetic of the product, leaving a soft and silky feeling on the skin. Cetyl alcohol is also used as a viscosity controlling agent.
Disodium EDTA
Est. %0.3
Function
Origin
A synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Fragrance
Est. %0.3
Function
Origin
Under trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Linalool
Est. %0.3
Function
Origin
A fragrant, volatile compound naturally present in many essential oils. It has a pleasant scent and is often used in skincare products as a fragrance. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
Hexyl Cinnamal
Est. %0.3
Function
Origin
A synthetic scent ingredient that produces a jasmine-like fragrance. According to the International Fragrance Association (IFRA), hexyl cinnamal is a skin sensitizer and allergen and so its use in skincare should be limited.
Hydrolyzed Elastin
Est. %0.3
Function
Origin
An elastic protein of animal origin that has been processed into smaller, water-soluble peptide fragments. It can be used to treat rough and chapped skin, as well as combat skin dryness.
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.
Coumarin
Est. %0.3
Function
Origin
A plant-based fragrant compound that occurs in sweet-smelling grass, sweet woodruff, and sweet clover. It has a sweet and vanilla-like scent in high concentrations and a similar scent to freshly mowed grass in low concentrations.
Geraniol
Est. %0.3
Function
Origin
A fragrant, volatile, plant-based, liquid chemical that can be naturally found in many essential oils (specifically rose, palmarosa, citronella). It has a rose-like scent. It is a potential irritant and may cause an allergic reaction in some people.
