This supplement contains glutathione, a powerful antioxidant often used to help brighten skin tone by temporarily reducing melanin production. While many people find it beneficial for skin radiance, scientific evidence regarding its long-term effectiveness for permanent skin whitening is still limited. For most individuals, oral glutathione is very safe and well-tolerated. However, minor side effects can occasionally occur, such as mild stomach upset, bloating, or a skin rash. To ensure it is safe and appropriate for your specific skin type and health, it is highly recommended to consult a dermatologist before starting the supplement.
