The Retinol 0.5 Oil

Time to say goodbye to the dry spells that sometimes follow retinol. With its oil-based formula, it kicks dryness to the curb without breaking a sweat. And when you throw squalane into the mix? It gets you ready for a nourishment upgrade that's ten times better. Tailor-made for the pros, this baby gets straight to business – no derivatives, just pure vitamin A. Apply post-cleansing on dry skin. Gently tap it in and avoid the under-eye area. Seal it with moisturizer. Follow it up with sunscreen in the AM. Start by using it twice a week, slowly increasing the frequency of use. Avoid using it alongside chemical exfoliants, strong actives and physical scrubs.
