Every formula starts with peptide actives that have a track record in cosmetic science, at concentrations we're proud to disclose.
A copper-peptide (GHK-Cu) complex included at a formulation-tested concentration to help skin appear firmer and more resilient over time.
A Matrixyl-type signal peptide blend formulated to visibly smooth the look of fine lines and improve overall skin texture.
Humectant-rich actives layered in to help skin look and feel more hydrated, plump, and comfortable day to day.
Our claims are cosmetic, not clinical — we formulate for how skin looks and feels, not to treat any condition.

Larkspur Labs formulas are cosmetics — designed to improve the appearance and feel of skin. They are formulated, manufactured, and labeled to comply with the Modernization of Cosmetics Regulation Act (MoCRA), and every product will ship with a full ingredient list, no hidden proprietary blends.
Our language is intentionally cosmetic: we describe how skin looks and feels — firmer, smoother, more hydrated — rather than making medical or structural claims. Larkspur Labs products are not intended to diagnose, treat, cure, or prevent any disease, and are not a substitute for medical or dermatological care.
We're currently finalizing formulations ahead of launch. Nothing on this site is currently available for purchase.
We're finalizing our first formulas now. Join the pre-launch list and we'll email you the moment pre-orders open.

No. Larkspur Labs makes cosmetic claims only — about how skin looks and feels — and is not intended to treat any medical condition.
