| Verdict | The US cosmetic-derm world's post-procedure gold standard. TNS — Tissue Nutrient Solution, a growth-factor complex derived from human fibroblast conditioned media — paired with signal peptides and barrier support. Clinical data on photoaging is published and serious. $295 is genuinely expensive, but the 4–6 week post-Fraxel case is exactly what this product was built for. | The Ordinary's gateway azelaic acid — a 10% suspension that does what prescription-strength 15–20% does, just slower. Azelaic acid is the calmest active in the rosacea/acne/hyperpigmentation arsenal: it kills C. acnes bacteria, suppresses melanin production, and reduces inflammatory redness simultaneously, all without the irritation profile of retinoids or BHA. Tolerable for most sensitive skin, pregnancy-safe, layers under SPF. The texture is the only meaningful complaint — slightly grainy and white-cast-y on first application until rubbed in fully. |
