Optimize: Skin & Hair

The gold-standard evidence-based topical for both photoaging (nearly every treated face improved vs none on placebo) and acne (strongly recommended first-line, better paired with benzoyl peroxide). Empower-first anchor. Note the honest tradeoff: a higher strength was more irritating without being more effective, so start low and slow; low phototoxic potential.

Topical ivermectin 1% cream cleared or nearly cleared papulopustular rosacea in ~38-40% (both pivotal trials). Strong, well-replicated; a first-line prescription topical for inflammatory rosacea.

For chronic hives, wet cupping roughly matched antihistamines and helped as an add-on. Narrow indication, small trials, likely partial expectation effect; present with both lenses.

Wound-healing, not cosmetic skin: healed 52% of stubborn diabetic foot ulcers within a year (vs 29%) and improved radiation-damaged tissue, but did NOT reduce major amputations. Situational to non-healing wounds; not a general skin lever.

As a diabetic-foot-ulcer add-on, ozone roughly halved amputations (RR 0.46) but on low-certainty evidence. Situational wound-care adjunct; weak evidence base, grade emerging.

Best evidence of this group's emerging levers: laser caps raise hair density vs sham in pattern hair loss, ~30 sessions smoothed fine lines and raised measured collagen; wound-healing evidence is very low-certainty. Reasonable for hair and photoaging, honest about the thin wound data.

Small skin-elasticity and hydration gains over 8-12 weeks in pooled trials, but MOST skin trials were funded by the companies selling the product (the input flags this honestly). Emerging with a standing conflict-of-interest caveat; not a retinoid-level lever.

Copper peptide GHK-Cu acts on skin-repair pathways with thin human skin data. Mechanistic promise, preliminary clinical evidence; education-level.

Animal wound-repair and collagen benefit, but topical GHK-Cu did NOT improve measured wrinkles or redness after laser resurfacing in humans; hair-follicle data is indirect. Genuinely mixed; keep preliminary and state the human null.
