Because the serum contains retinol, it is wise to let your skin adapt, especially if you are new to vitamin A cosmetics or have easily reactive skin. A common approach is to apply it in the evening only, starting with one or two nights per week for the first two weeks. If no redness, peeling, or tightness appears, increase to every other night, and then to nightly use if your skin tolerates it. This gradual build-up helps reduce the risk of irritation while allowing the retinol to work consistently.
Use a small amount — usually two to three drops — and spread it evenly over the whole face, avoiding the immediate eye area and lips. If your skin feels dry or flaky, you can apply a moisturizer either before or after the serum. Applying moisturizer first creates a buffer that slows absorption; applying it after seals in the serum. Choose whichever feels more comfortable, but do not layer the serum over broken or irritated skin.
During the adaptation period, avoid combining the serum with strong exfoliating acids (such as high-percentage AHA/BHA) at the same time of day. If you use other active products, alternate them — for example, use the serum in the evening and a gentle acid-free routine in the morning. If your skin becomes persistently red, stinging, or very flaky, reduce the frequency and give it a few days to recover before continuing.
If you are pregnant, breastfeeding, or using intensive active skincare, check with a specialist before using a retinol product.
