This was a single-center, double-blinded, randomized, controlled cosmetic clinical trial to investigate the efficacy and tolerance of dark spot corrector serum and regimen skincare products when used over the course of 12 weeks (spot treatment applied twice daily) and an additional 4-week maintenance period (spot treatment applied once daily) by women with clinically determined moderate discrete hyperpigmentation (solar lentigines \[age spots/sun spots\]) on the global face, and self-perceived very bothersome hyperpigmentation (darkening), including spots, on the global face.
Subjects were randomized to either the basic skincare regimen or the enhanced skincare regimen. Both cells tested the dark spot corrector serum. This is a new hydroquinone-free serum formulated to address hyperpigmentation (melasma, solar lentigines, post-inflammatory hyperpigmentation). The basic regimen comprised of the basic gentle foaming cleanser, the dark spot corrector serum, a basic moisturizer and sunscreen. The enhanced skincare regimen comprised of the sponsors skincare products including a 0.25% retinol night cream, a 30% vitamin C serum, and a tinted sunscreen moisturizer.
