Yes, you can use glutathione and niacinamide together in your skincare routine. Glutathione is a powerful antioxidant that helps protect the skin from oxidative stress and promotes a brighter complexion. Niacinamide, on the other hand, is a form of vitamin B3 that offers multiple benefits to the skin, including reducing inflammation, regulating sebum production, and improving the overall texture of the skin.

Both ingredients are well-tolerated by most skin types and can complement each other when used together. Glutathione can help enhance the antioxidant properties of niacinamide, while niacinamide can contribute to the overall brightening effects of glutathione. Additionally, niacinamide has been found to help stabilize glutathione levels in the skin, making it a suitable companion ingredient.

However, as with any new skincare product or ingredient, it is always a good idea to perform a patch test on a small area of your skin to ensure compatibility and to monitor for any adverse reactions. If you have any concerns or specific skin conditions, it is best to consult with a dermatologist or skincare professional before incorporating these ingredients into your routine.
