YSL Beauty offers a range of products, including skincare, foundation, lipstick, and fragrance. Here are some details about the ingredients and materials used in YSL Beauty products:

Skincare:

• YSL Beauty selects quality ingredients that comply with the strictest regulations.
• No specific ingredients or materials are mentioned.

Foundation:

• YSL All Hours Foundation contains water, cyclohexasiloxane, alcohol denat, and isododecane, among other ingredients.
• The water used in cosmetics is purified and deionized, which means that almost all of the mineral ions inside it are removed. This helps the products stay more stable over time.
• Cyclohexasiloxane is a light-feeling, volatile silicone that gives skin a unique, silky, and non-greasy feel. It has excellent spreading properties and leaves no oily residue or build-up.
• Alcohol denat is a super common and super debated skincare ingredient. Its often used in makeup products mixed with silicones to give shine and slip to the product. Its also great for cleansing dirt and oil from the skin as well as for taking off make-up.

Lipstick:

• YSL Pur Couture Satin Lipstick contains propylene glycol dibenzoate, octyldodecanol, pentaerythrityl tetraisostearate, among other ingredients.
• Octyldodecanol is a clear, slightly yellow, odorless oil thats a very common, medium-spreading emollient. It makes the skin feel nice and smooth and works in a wide range of formulas.
• Pentaerythrityl tetraisostearate is a clear, odorless, very light emollient ester that helps to achieve light textures. It has great spreadability, a good slip, and a silky skin feel. Its ideal to solubilize sunscreen agents and fragrances. Its also touted as a volatile (evaporates from the skin rather than absorbs into it) silicone alternative, especially to replace Cyclomethicone mixes.
• Fragrance is also listed as an ingredient, but it is a generic term on the ingredient list that is made up of 30 to 50 chemicals on average (but it can have as much as 200 components!). If you are someone who likes to know what you put on your face, then fragrance is not your best friend - theres no way to know what’s really in it.
