Skin lightening primarily aims to reduce overall melanin for a paler complexion or significantly fade severe hyperpigmentation like melasma and dark spots. This often involves potent ingredients or procedures in a "skin lightening treatment" to actively inhibit pigment production.

In contrast, skin brightening focuses on enhancing radiance and luminosity. It addresses dullness, improves skin tone evenness, and promotes a healthy glow through gentle exfoliation and boosting cellular turnover, without altering natural skin color. While both seek a more uniform appearance, brightening is about vitality, whereas lightening targets actual pigment reduction.

People usually seek skin lightening to address issues such as:

• Hyperpigmentation
• Dark spots
• Melasma
