2. Use:

Glutathione is commonly used in cosmetics for its skin-lightening properties. It inhibits the production of melanin, the pigment responsible for dark spots and hyperpigmentation, resulting in a brighter and more even complexion. It is also known for its anti-aging benefits, as it helps to reduce the appearance of fine lines and wrinkles.

3. Usage Glutathione:

Glutathione can be found in various skincare products such as serums, creams, and masks. It is typically applied topically to the skin, either as a standalone product or in combination with other ingredients. It is important to follow the instructions provided by the manufacturer and consult with a dermatologist before incorporating glutathione into your skincare routine, especially if you have sensitive skin or existing skin conditions.
