A Beginner's Guide to The Ordinary Skin Care

What to use in the evening: Retinol 1% in Squalane ($7). Retinol can sometimes cause irritation when using it for the first time; if this is the case, start using retinol once or twice a week and build up to more once the skin is used to it. Sun protection is very important when using retinol products, so always wear SPF during the day. Moisturize with 100% Plant-Derived Squalane ($8), a noncomedogenic (nonclogging) product that will maintain moisture in the skin without clogging the pores.
