Inside-out

Oral collagen helps hydration and elasticity, not wrinkles

A 2026 meta-analysis of randomized trials found moderate gains in elasticity (strongest at 12 weeks) and smaller gains in hydration. After sensitivity testing there was no reliable effect on wrinkles.

Peptides

The FDA’s peptide reversal, explained

About 14 of 19 restricted peptides were moved to a category that allows compounding, which is not FDA approval. In late July an advisory panel recommended 6 of 7 for the compounding list, against the agency’s own scientists. The vote is nonbinding, and rulemaking could take 12 to 24 months.

Exosomes in dermatology: promising, not proven

A scoping review of 17 human studies found 76% reported improvements in wrinkles, pigment, elasticity, hydration or scars. Most studies were small, short and non-randomized. Adverse events were uncommon but included granulomas, necrosis and allergic reactions after injection.

Hormones

In a 13-week gene analysis of 21 patients treated in the nasolabial folds, poly-L-lactic acid activated extracellular-matrix and regenerative genes with minimal inflammation. Calcium hydroxylapatite showed more pro-inflammatory activity.
