Clinical Skincare Results
Conducted by Callender Center for Clinical Research
A 12-week clinical trial with 28 women aged 47–75 assessed efficacy, tolerability, and satisfaction.
The subjects followed a daily skin care regimen that consisted of our cleanser, toner, serum, sunscreen SPF 40, night-time hydrating cream, and retinol moisturizing cream.
3 out of 4 Reported brighter, more radiant skin that felt and looked more hydrated, noticeably softer, and smoother in texture.
96% reduced redness without burning or irritation.
52% enhanced skin vitality, improved tone evenness, and reduced hyperpigmentation and fine lines.
