In a routine you'll most often find it in serums and creams. Use it after cleansing, in the evening, before applying hydrating and repairing products.
It's best suited to normal, combination, and oily skin, especially skin with signs of aging or prone to acne. Sensitive skin can use it too, but gradually and carefully.
Retinal helps speed up skin renewal, reduce the look of fine lines, improve texture, and reduce imperfections and acne. Skin ends up smoother, firmer, and more even.
It combines well with hydrating and calming ingredients like hyaluronic acid, ceramides, and panthenol, which lower the chance of irritation. At first, avoid combining it with strong acids (AHA, BHA) and other retinoids in the same routine.
Introduce it gradually - once a week at first, then twice a week, and more often later depending on how your skin tolerates it. Always use it in the evening, and sun protection is a must during the day.
