A drip people look to for overall skin tone.
This is an antioxidant the body makes on its own. It is understood to slow the process that produces the pigment which darkens skin, and to steer production toward the lighter pigment rather than the darker one. In Korea clinics mainly use it for skin tone and pigment. Unlike taking it by mouth, it skips absorption so blood levels rise quickly.
Glutathione IV is an aesthetic IV drip that delivers an antioxidant to slow how dark pigment forms. It is also understood to shift pigment production toward the lighter kind. In Korean clinics it is mainly used to brighten a dull tone; it does not remove melasma that has already formed.
