Myristoyl Hexapeptide-5 powder for blemish-prone skin, redness-care, pore-targeted, and post-acne mark cosmetic formulas.
Myristoyl Hexapeptide-5 (Powder) is a cosmetic peptide powder for blemish-prone skin, redness-care, pore-targeted, and post-acne mark formulas.
This peptide is positioned for anti-P. acnes cosmetic concepts and is especially useful in lightweight gels, spot-care products, and leave-on serums where the formula needs a modern peptide alternative to traditional blemish-care actives.
Product Description: Use Myristoyl Hexapeptide-5 powder when developing advanced acne-prone skin products that need both a blemish-care story and a refined peptide-active image. The powder format lets formulators build their own solvent system, pore-delivery strategy, and active level.
| Formula target | Benefit direction |
|---|---|
| Blemish-prone skin | Supports anti-P. acnes cosmetic positioning with reported MIC against acne bacteria of 31 ug/ml. |
| Redness care | Useful for spot-care products where fast visible redness reduction is part of the concept. |
| Spot appearance | Development data describe visible spot improvement over 36 hours in the tested context. |
Usage: Blemish-care gels, spot-care products, redness-care serums, pore-targeted leave-on products, and lightweight formulas for acne-prone skin.
Mixing method:
- Pre-dissolve or pre-disperse into a small compatible water/glycol phase before adding to the main batch.
- Add during cool-down, preferably below 40°C, and avoid prolonged heat exposure.
- For spot-care products, confirm dispersion, skin feel, and compatibility with exfoliating acids or antimicrobial-support ingredients.
- Check final pH, clarity, odor, color, and active stability before scale-up.
Usage rate: typically 0.001-0.01% active powder. For intensive spot products, validate higher delivered levels carefully in the finished formula.
Product characteristics: white to off-white powder.
Solubility: Pre-disperse into a suitable solvent or premix; confirm dispersion and active delivery in the finished base.
Storage: Keep tightly closed, dry, protected from light and heat. Refrigerated storage is preferred for long-term peptide stability.
