What ingredients are needed in skincare?

Effective skincare ingredients are essential for delivering specific benefits to the skin. With ample options available, it’s important to determine your individual skin concerns to help you choose the right skincare ingredients.

For boosting hydration, look for moisture-retaining ingredients such as hyaluronic acid, glycerin, and squalane. If you’re dealing with dullness or discolouration, antioxidants like vitamin C and niacinamide can help brighten and even out the complexion. And, for breakouts or visible signs of ageing, you can turn to potent ingredients like retinol and salicylic acid to mitigate your concerns.

VITAMIN C

Vitamin C

Thanks to its status as an antioxidant, there are many vitamin C benefits for skin. Vitamin C is known for its ability to brighten and even skin tone while protecting the skin against the free radicals that contribute to premature ageing.

Retinol

This vitamin A derivative is a key ingredient in anti-ageing and blemish-prone skincare. Using retinol for skin can stimulate skin cell turnover, which helps reduce breakouts, improve skin firmness, and smooth the appearance of fine lines and wrinkles.

Squalane

A plant-derived lipid that supports the function of the skin moisture barrier, squalane benefits the skin by locking in moisture at the surface – leaving skin soft, supple, and hydrated.
