COSRX The Retinol 0.1 Cream

COSRX The Retinol 0.1 Cream

How it works

Retinol is the one active that has to be introduced slowly, so the useful question about a retinol cream is where it starts rather than how strong it goes. This is the entry-strength cream in COSRX's retinol line, and it carries retinol with shea butter, soybean oil and sunflower seed oil cushioning it. It goes on in the evening only, after cleansing and toner, and a plain moisturizer can go over the top. COSRX directs three evenings a week at first, then every other night once skin tolerates it. Sunscreen the next morning is part of using a retinol at all.

How to use

  1. Use the Retinol 0.1 Cream in the evening only, after cleansing and toner, on dry skin.
  2. A pea for the whole face, kept clear of the eyelids and the corners of the nose and mouth.
  3. Toner first, this second, then a plain moisturizer over the top if skin wants one.
  4. COSRX's own direction is three evenings a week at first, building to every other night as skin tolerates it. Do not pair it with an exfoliating acid, and do not use it in the morning.

  • Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.

  • Using topical vitamin C can result in less cell damage and better-looking skin.
