The Clinical Studies

OS-01 FACE MOISTURIZER Efficacy Study — Published in the Journal of Cosmetic Dermatology

A 12-week, third-party split-face, double-blind clinical study evaluated the effects of OS-01 FACE and the OS-01 Peptide™ in 22 female participants (ages 47–65) with dry, normal, and combination skin. Participants applied OS-01 FACE MOISTURIZER 2x daily to one side of the face and an identical peptide-free "vehicle" formula to the other, isolating the peptide's effect from the rest of the formulation. Barrier function, wrinkles, texture, and radiance were measured with instrumental devices (Vapometer, Antera 3D, VISIA CR), while fine lines/wrinkles, skin tone, texture, firmness, elasticity, radiance, and overall appearance were evaluated visually and tactilely by expert clinical graders. Published in the Journal of Cosmetic Dermatology, Zonari et al., 2024.

The results after 12 weeks1:

  • 100% showed visibly smoother skin with improved overall appearance (blind expert grading)
  • 96% showed more even, radiant, and firmer-looking skin with less visible pores (blind expert grading)
  • 91% showed improved elasticity (blind expert grading)
  • 86% had reduced appearance of fine lines and wrinkles (blind expert grading)
  • +14% increase in barrier strength (Tewameter)
  • +17% improvement in visible radiance (VISIA-CR)

OS-01 BODY MOISTURIZER Efficacy Study — Published in the Journal of Cosmetic Dermatology

A 12-week, double-blind, third-party clinical study evaluated the effects of OS-01 BODY MOISTURIZER on body skin hydration, barrier function, texture, and appearance. 60 participants were divided into two groups: one applied OS-01 BODY twice daily, while the other applied a placebo moisturizer twice daily. Hydration and trans-epidermal water loss (TEWL) were measured with instrumental devices (Corneometer and Tewameter). Participants also reported subjective improvements. Published in the Journal of Cosmetic Dermatology, Zonari et al., 2025.

The results after 12 weeks1:

  • 93% of participants reported improved skin hydration
  • +38% improvement in forearm and upper arm hydration (corneometer)
  • +41% improvement in skin barrier on forearm and +35% on upper arm (tewameter)
  • 70% reported improved skin texture
  • 70% reported improved overall appearance

    Delivery was less than satisfactory. Just threw my order on the pavement. Previous deliveries were placed in the mailbox, but not this one. I found it under my bench.

    Love this lotion!

    I’ve been using this body lotion for quite awhile now, maybe almost a year! It is the best in so many ways. It penetrates the skin with no greasy feel, only moist, soft supple skin! It has smoothed out rough patches on the back of my arms, refined texture everywhere. It has spoiled me, in fact I never travel without it packed in my suitcase.

    I’ve been using this moisturizer for over a year now and I can feel and see the difference in my complexion. My skin is smoother and not flaky.

    Expensive but seems to work

    I’ve had better results with this than the face cream. The back of my hands are softer and much less scaly from sun exposure. I’m still evaluating results.
