COSRX The Retinol 0.5 Oil
Retinol, a form of vitamin A, one of the most proven ingredients to improve wrinkles & skin texture. This serum contains 0.5% retinol for intermediate-level retinol users looking for a highly concentrated, youth booster. (If you're new to retinol, start with COSRX's 0.1 retinol cream instead). This formula is made with squalane - an oil-like plant derived substance - which moisturises, soothes and protects from external irritation.
Vitamin A can stress & dry out the skin, so it's important to allow the skin to adjust to using a new strength of retinol: start with just 2x per week, then increase gradually to avoid irritation. It is also important to protect the skin barrier while using a vitamin A, so minimise the use of other actives and focus on soothing, moisturising products.
To use: in the evening, cleanse skin and dry fully (applying retinol to damp skin can increase irritation). Let sit for 20 minutes, then follow with moisturiser. It's important to sufficiently protect the skin while using retinol, so follow-up with spf 50 in the morning.
