Apply a pea-sized amount to cleansed face and neck in the evening only. When using Retinol, we recommend using an SPF in the morning.
Our dermatologists would always recommend to patch test before your use this product for the first time. It is important to build up your intolerance to retinol, therefore we recommend using this product every 5-7 days and gradually increasing to 2-3 days. If irritation occurs, reduce down your usage.
We wouldn’t recommend using this product with other products containing: benzoyl peroxide, BHAs, AHAs.
