Can I use sh-Octapeptide-4 with sh-Polypeptide-7?
Works well together
sh-Octapeptide-4 and sh-Polypeptide-7 are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
sh-Octapeptide-4Active
- ✓Synthetic analogue of Leu-Enkephalin (leucine-enkephalin, an endogenous opioid neuropeptide) that modulates sebum production and reduces excess seborrhea — making it particularly relevant for oily, combination, and congestion-prone skin types
- ✓Antioxidant and chelating activity helps protect skin cells against oxidative stress and metal-ion catalyzed free radical damage
- ✓Barrier-strengthening effect via skin conditioning; produced by Spec-Chem Industry Inc under the trade name SpecPed Sh-O4P
- ⚠As with other recombinant human peptides, a theoretical growth factor concern applies in specific disease contexts; not demonstrated as a risk at normal cosmetic concentrations
sh-Polypeptide-7Active
- ✓Recombinant human polypeptide produced by E. coli fermentation — likely a keratinocyte growth factor (KGF/FGF-7) family member that supports keratinocyte proliferation and skin renewal
- ✓Skin-protecting and anti-seborrheic activity in the context of a multi-factor growth factor complex, contributing to overall skin balance and barrier integrity
- ✓Combined with other sh- peptides (sh-Decapeptide-7, sh-Octapeptide-4, sh-Oligopeptide-9) as part of a Caregen-type growth factor cocktail targeting comprehensive skin rejuvenation
- ⚠As with all recombinant human growth factors in topical formulations, a theoretical concern exists regarding use by individuals with active skin malignancies; considered safe at cosmetic concentrations for intact healthy skin
