Anti-pigmenting Effect of a Routine of Facial Products in Subjects With Melasma

This 6 month, comparative study assesses the benefit of a dermocosmetic regimen (Serum B3 + B3 retinol night cream) for 6 months compared to hydroquinone 4% (the gold standard in hyperpigmentation) followed by the dermocosmetic regimen for 3 months or the Kligman Trio for 3 months followed by the dermocosmetic regimen for 3 months in adult women with melasma on the face.

Study objective

1. Assessing the antipigmenting efficacy of the routine (serum B3 + B3 retinol night cream) in women with melasma.
2. Evaluation of Kligman Trio (KT) (Vitacid Plus) compared to the routine (serum B3 + B3 retinol night cream)
3. Evaluation of Hydroquinone 4% (HQ 4%) compared to the routine (serum B3 + B3 retinol night cream).
4. Assessment of the routine maintenance with SERUM B3 + retinol B3 night cream after 3 months of use of Klingman Trio (KT)(Vitacid plus) and HQ4%
