How to combine Vitamin C and Retinol
As Retinol and Vitamin C serums operate best at different pH levels, using them at the same time can cause them to be less effective. It can also irritate your skin. Using one in your morning routine and one at night allows them to work at their correct pH and most effective.
We recommend using a radiance-boosting Vitamin C product in the morning to help brighten your skin for the day ahead and protect skin against pollution and other daily environmental stressors.
As Retinol boosts cell turnover and new cells are more delicate, it can cause photosensitivity. Massaging it in when the sun has gone down at night helps to keep it away from UV light.
The key to starting any new skincare routine is finding what works for you gradually. Try this combination of powerful ingredients once a week and see how your skin type reacts before increasing the frequency to two or three times a week. You may also find alternating Retinol and Vitamin C serums on consecutive nights gives the best results for your skin. If you have sensitive skin, start slow and with lower strengths.
