Glutathione soap is a type of soap that is generally enriched with l-glutathione, an antioxidant compound that is typically produced by a healthy human body. The body normally produces less of this substance as it ages. L-glutathione is said to help counteract the damaging effects of free radicals, helping to slow the aging process and prevent degenerative diseases. It may help to prevent and reverse sun damage to the skin. Applying l-glutathione to the skin in the form of glutathione soap is said to help stifle the skin's production of melanin, or pigment, to lighten the skin and help minimize the appearance of skin discolorations and scars.
Skin-care experts believe glutathione soap can have a number of skin-care benefits. The active ingredient, l-glutathione, is believed to be one of the most powerful antioxidants available. Soaps, creams, and lotions containing l-glutathione are often used to help improve the appearance of fine lines and wrinkles, to help skin maintain its youthful elasticity and appearance. Many people believe that glutathione soap can help improve skin tone and complexion. It may help to prevent the occurrence of acne, and may even help to fade scar tissue left by acne breakouts.
Soap, lotions, and creams containing l-glutathione are often used to lighten skin. A number of skin conditions can cause darkening and discoloration of the skin, such as melasma. Age spots, sun spots, freckles, and general hyperpigmentations of the skin are all said to benefit from the regular application of glutathione soap. The results of this skin treatment are generally cumulative. Most people who wish to benefit from the skin-lightening effects of l-glutathione are advised to apply the soap, cream, or lotion daily for several weeks.
Glutathione soap is believed to cause fewer harmful side effects than other skin lightening agents. That's because the substance is naturally produced inside the normal body, and therefore isn't usually caustic to the skin.
Most soaps made with l-glutathione include additional ingredients considered beneficial for skin health. These often include other antioxidants, such as vitamin C, vitamin A, or vitamin E. Agents such as alpha lipoic acid may be added to quality glutathione soaps, since they are believed to help enhance and support the antioxidant effects of l-glutathione. Moisturizing ingredients often also appear in these soaps. Dietary supplements containing l-glutathione may also be ingested to support the health of the body as a whole, but the effects of these supplements on skin health have not yet been fully documented.
