- Skin effectClassification by causes of dark circles and appropriate evaluation method of dark circles
In a randomized, double-blind, placebo-controlled split-face trial, 24 people with mixed-type dark circles used a test product containing 3% vitamin C, 0.1% vitamin A and 0.5% vitamin E for eight weeks. Brightness (L*), melanin index and image-analysis lightness improved significantly on the treated side compared with the placebo side.
Human trial · 2016 · 24 people · adults with mixed-type dark circles · Instrument-measured brightness, melanin index and skin thickness in mixed-type (pigment plus vascular) dark circles over eight weeks. · Three actives were used together. 24 people took part, all with the mixed type of dark circles; a separate 100-person study was used first to choose which measurements to trust. The abstract reports instrument readings.
- Skin effectA randomized controlled study to evaluate the depigmenting activity of L-ascorbic acid plus phytic acid-serum vs. placebo on solar lentigines
In a double-blind, vehicle-controlled trial of 30 people with two or more solar lentigines, a serum with 10% L-ascorbic acid and 2% phytic acid lowered the pigmentation index of the treated lesions over three months while the vehicle-treated lesions stayed stable (P <= 0.003 from month 1 to month 4). Six adverse events, mostly halo depigmentation, were judged possibly related to the product.
Human trial · 2011 · 30 people · healthy subjects with two or more solar lentigines · Pigmentation index, dermoscopic pigmentation and brightness (L*) of solar lentigines over three months, with two months of follow-up. · The serum combines two actives. Each person applied the product to one side of the body and the vehicle to the other. 30 people, and six halo-depigmentation events were possibly related to the product. The authors call for larger studies.
- Skin effectNovel Vitamin C and E and Green Tea Polyphenols Combination Serum Improves Photoaged Facial Skin
In 31 women aged 43-65, a serum combining vitamins C and E with green tea polyphenols produced statistically significant improvements in all clinically graded parameters over 12 weeks, including enhanced skin smoothness and radiance, plus an ultrasound-measured increase in skin density.
Human trial · 2021 · 31 people · healthy women aged 43-65 (mean 57.9) · Women aged 43-65 with photoaged facial skin, applying the serum twice daily for 12 weeks. · Radiance was a clinical grading parameter.
- Skin effectAnti-aging and brightening effects of a topical treatment containing vitamin C, vitamin E, and raspberry leaf cell culture extract: A split-face, randomized controlled trial
In a split-face randomized controlled trial of 50 women, a serum with 20% vitamin C, vitamin E and raspberry leaf cell culture extract significantly improved skin radiance measured by Glossymeter GL200, along with skin colour and elasticity, over 2 months.

In a 12-week hemi-member, randomized, double-blind, comparative study of 18 patients over 60 with Bateman purpura, twice-daily 5% topical vitamin C improved skin symptoms and increased dermal thickness and elasticity on the treated side versus control.
Human trial · 2018 · 18 people · patients over 60 with Bateman purpura · Adults over 60 with Bateman purpura (senile purpura) applying 5% topical vitamin C twice daily for 12 weeks. · Small sample (18 patients) and a single-centre study; the population is photodamaged older skin.
