Can prescription hydroquinone and prescription retinol be used together with glutathione (oral supplement as well as topically)?

Using hydroquinone, retinol, and glutathione together can be done, but it's important to carefully manage the application to avoid skin irritation. Here's a possible regimen:1. Hydroquinone is a skin-lightening agent used to treat hyperpigmentation and age spots. It's typically applied once or twice daily.2. Retinol is a form of vitamin A that can help with signs of aging by increasing cell turnover and promoting collagen production. It's typically used at night, as it can make your skin more sensitive to the sun.3. Glutathione is an oral supplement, glutathione can act as an antioxidant and may help improve skin texture and tone. Topically, it's typically used for its potential skin-lightening effects. It can be used in the morning or at night.Remember to go slowly when introducing new products into your skincare routine, especially ones as potent as hydroquinone and retinol. Start with lower concentrations and gradually increase as your skin tolerates.Also, keep in mind that these products can make your skin more sensitive to the sun, so be diligent with sun protection.
