How to Use Retinol and Vitamin C Together --- If youโre using both retinol and vitamin C in your routine, itโs best to apply the vitamin C in the morning and retinol at night. This is because vitamin C is best applied during the day to protect the skin from external toxins, while retinol is best applied at night when the skin is in repair mode. Start with a low concentration of both retinol and vitamin C and gradually work your way up to higher concentrations as your skin becomes more
accustomed to the ingredients. Always wear sunscreen during the day when using vitamin C, as it can increase your skinโs sensitivity to the sun. It can take several weeks or even months to see the full benefits of using retinol and vitamin C together. If you have sensitive skin or are unable to use retinol or vitamin C, there are plenty of other skincare ingredients that can provide similar benefits: Niacinamide can help to improve the appearance of fine lines and wrinkles, while also brightening the skin and reducing the appearance of pores. AHAs (Alpha
hydroxy acids) like glycolic acid and lactic acid can help to exfoliate the skin, and improve texture. And reduce hyperpigmentation.
