Detailed answer

Skin brighteners are not recommended for use on tattoos. Tattoo ink is placed deep within the dermis layer of the skin, while skin brighteners typically work on the surface or upper layers of the skin. Using skin brighteners on tattoos may cause uneven fading or discoloration of the tattoo. Additionally, skin brighteners often contain ingredients like retinol or hydroquinone, which can be harsh and irritate the skin. It is best to avoid using skin brighteners on tattoos to protect the integrity and longevity of the tattooed design.
