Science
Mechanism of Action
SH-DECAPEPTIDE-1, often recognized as sh-Oligopeptide-1 or Epidermal Growth Factor (EGF), actively promotes epidermal cell proliferation, fostering skin renewal and repair at the cellular level. It is known to bolster collagen and elastin synthesis, thereby strengthening the epidermal barrier, modulating fibroblast activity, and increasing keratinocyte growth factor (KGF) expression. Concurrently, SH-POLYPEPTIDE-2, a synthetic recombinant analog of human Thioredoxin (TRX), stimulates dermal cell growth and proliferation. It provides crucial protection against oxidative stress by neutralizing free radicals and inhibiting apoptosis. This synergistic action enhances dermal tissue organization, accelerates new skin cell generation, supports collagen production, and significantly improves skin elasticity, contributing to a visible reduction in existing lines and wrinkles while preventing the formation of new ones. A related fusion peptide, R-(Sh-Polypeptide-2 Decapeptide-40), further contributes by conditioning and protecting the skin, enhancing its texture and hydration, and forming a barrier against environmental aggressors.

Stability
Due to the potentially large molecular size characteristic of peptides like sh-Polypeptide-1, specialized delivery systems such as liposomes may be crucial to enhance both stability and penetration through the stratum corneum. Factors such as pH, charge, molecular weight, concentration, and background electrolytes are known to influence the skin permeation of peptides.
Safety
Safety Profile
Information specifically for the combined 'SH-DECAPEPTIDE-1 SH-POLYPEPTIDE-2' regarding CIR, SCCS, or FDA status is not available. However, a closely related fusion peptide, R-(Sh-Polypeptide-2 Decapeptide-40), is generally considered safe for topical use, but potential side effects include skin irritation, redness, and allergic reactions, warranting a patch test. For sh-oligopeptide-1 (often associated with SH-DECAPEPTIDE-1), it is authorized as a cosmetic with general usage concentrations, though long-term risks remain unknown. Clinical studies for sh-oligopeptide-1 have been noted to sometimes lack scientific basis regarding preclinical bioactivity.
