What ingredients are needed in skincare?

Efficacious ingredients play a crucial role in skincare products to deliver targeted benefits to the skin. With so many skincare ingredients at your disposal, we suggest starting by identifying your unique skin concerns to find out which is right for you.

For hydration, you’ll want to seek out moisture-locking ingredients like hyaluronic acid, glycerin, and squalane. If you have dullness or hyperpigmentation concerns, antioxidants like vitamin C and niacinamide can work to unify and brighten skin tone. Meanwhile, ingredients like retinol and salicylic acid are key fixtures in blemish-prone and anti-ageing skincare routines.

VITAMIN C

RETINOL

RETINOL

One of the most powerful anti-ageing and anti-blemish ingredients for skin, this vitamin A derivative is used to boost collagen, smooth texture, and reduce the appearance of fine lines and breakouts.
SQUALANE

SQUALANE

A plant-derived lipid that’s used to fortify the skin moisture barrier. Squalane benefits the skin by locking in moisture at the surface – leaving skin soft, supple, and hydrated.
