About Skin, hair & aesthetic
- What they are
- Skin, hair, and pigmentation compounds — some injected, some formulated into topicals.
- How they're run
- Topicals go on clean skin daily; injectables run in short courses. Either way the timescale is months.
- What to watch
- Melanocortin compounds darken existing moles and can trigger nausea and flushing — get a skin check before and during. Topical peptides are cosmetic and act only where applied.
