简要总结
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 16 weeks 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.
详细描述
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.

研究组 & 干预措施
Basic Skincare Regimen
Gentle foaming Cleanser - This was administered in white airless bottle labeled "Foaming Cleanser". The patient was to use this product in the morning and evening to cleanse their face. The patient was to pump 1 to 2x and wash their face with warm water and gently dry their face.
Daily Moisturizer - This was administered as a white 3 oz tube labeled "daily moisturizer". Patients applied this product after their experimental product, the pigment corrector.
Sunscreen SPF 50 Neutrogena - The clinical study site wrapped this product in duct tape and labelled as Sunscreen SPF 50. Patients were to use this product as their last step in their routine in the morning. They were asked to follow FDA guidelines of reapplication every 2 hours and if they were in direct sunlight.
干预措施: Cosmetic dark spot corrector serum (Other)
Enhanced Skincare Regimen
Gentle foaming Cleanser - White airless bottle labeled "Foaming Cleanser". The patient was to use this product in the morning and evening to cleanse their face. The patient was to pump 1 to 2x and wash their face with warm water and gently dry their face.
Vitamin C (30%) Serum -Product wrapped in duct tape and labelled this product Vitamin C Serum. Patients applied 1-2 pumps of the Vitamin C Serum to the entire face, avoiding the eye area after application of the Dark Spot Corrector. Application was morning and evening.
Tinted Sunscreen SPF 45. Product wrapped in duct tape and labelled as Tinted Sunscreen SPF 45. Patients were to use this product as their last step in their routine in the morning.

结局指标
主要结局
Measurement of Clinical Efficacy Parameters by Clinical Grader
时间窗: Baseline, week 2, 4, 8, 12, and 16
Clinical grading efficacy parameters measured by blinded clinical grader including skin tone evenness and discrete hyperpigmentation (age spots/sun spots) on the global face; and for dark spot intensity (visual), dark spot size (visual), and dark spot appearance on each target dark spot. Grading was performed on a 10-point Griffith's scale, where 0 = best possible outcome 9= severe skin condition. A decrease in score/ value indicates an improvement.
