Absolutely! Ascorbyl glucoside and retinol can be used together in your skincare routine. Ascorbyl glucoside is a stable form of Vitamin C, which is known for its antioxidant properties and ability to brighten the skin. Retinol, on the other hand, is a form of Vitamin A that promotes cell turnover and collagen production.

When using these two ingredients together, it's important to introduce them gradually into your routine to allow your skin to adjust. Start by using them on alternate days or even every few days, and monitor how your skin responds. If you experience any irritation or sensitivity, you may need to reduce the frequency of use or adjust the concentration of the products.

Additionally, it's important to note that both ascorbyl glucoside and retinol can increase the skin's sensitivity to the sun. Therefore, it's crucial to apply a broad-spectrum sunscreen with a high SPF during the day to protect your skin from harmful UV rays.

Overall, combining ascorbyl glucoside and retinol can provide multiple benefits for your skin, including brightening, anti-aging, and collagen-boosting effects. Just remember to start slowly and listen to your skin's needs.
