Listed when one of a peptide's three researched benefits relates to skin & glow. Strongest evidence first. Inclusion is not a recommendation, and some listed effects are unproven or failed in trials.

Trial-backed

Larger randomized human trials exist, positive or negative, but no US approval for the uses discussed.

  1. Glutathione

    Raises body glutathione, Skin lightening, mixed trials, Fatty liver, small pilot

    02 Skin lightening, mixed trials

    • Skin lightening: 4-week RCT (n=60) of 500 mg/day oral GSH reduced melanin index at some sites vs placebo; a later 12-week Indonesian RCT of a GSH combination found no significant overall improvementhuman RCTs, mixed171819

    01 Firmer skin, small cosmetic studies

    • Skin anti-aging: placebo-controlled 12-week cream studies in women (n=41-71) improved laxity, firmness, density/thickness, fine lines and wrinkles, mottled pigmentation; increased collagen in 70% vs 50% vitamin C, 40% retinoic acidhuman, small controlled cosmetic studies, some unpublished conference data1

    02 Wound healing, mostly animal

    • Wound healing: accelerated wound closure, angiogenesis and antioxidant enzymes in rabbits, rats, pigs, dogs; improved diabetic/ischemic wounds (animal); Phase 2 topical gel wound trial registered12

  3. Snap-8

    Softer expression lines, Finer lines in multi-peptide serums, Wrinkle claims, manufacturer only

    01 Softer expression lines

    • Softens expression lines/wrinkles: microneedle patch with 0.03% SNAP-8 (plus other actives) improved periorbital wrinkle roughness vs placebo patch at 14-28 dayshuman split-face study, n=21; not isolated56

    02 Finer lines in multi-peptide serums

    • Multi-peptide serums/patches containing it improved fine lines, hydration, firmness over 12-24 weeksuncontrolled human studies, manufacturer-run; can't attribute to Snap-85
