Can I use sh-Octapeptide-4 with sh-Oligopeptide-9?
Works well together
sh-Octapeptide-4 and sh-Oligopeptide-9 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-Oligopeptide-9Active
- ✓Recombinant human oligopeptide that functions as a skin-conditioning active, supporting moisture retention and surface skin texture in multi-factor growth factor complexes
- ✓Humectant properties help draw water into the skin, complementing the structural remodeling activity of co-formulated signal peptides and growth factors
- ✓Used as part of a growth factor cocktail in premium K-beauty creams targeting skin rejuvenation, skin softness, and overall luminosity
- ⚠As with other recombinant human peptides, theoretical growth factor concern in specific disease contexts; not demonstrated as a risk at cosmetic concentrations
