Science
Mechanism of Action
As a member of the oligopeptide family, OLIGOPEPTIDE-155 is hypothesized to function by stimulating the skin's natural production of collagen and elastin, key proteins for maintaining skin structure and elasticity. This action is generally understood to help reduce the appearance of wrinkles and improve overall skin firmness. Oligopeptides also possess inherent moisturizing properties, contributing to skin hydration, and can influence cellular regeneration processes at deeper skin layers. Examples from the oligopeptide class, such as Oligopeptide-20, support normal skin growth and repair, while Oligopeptide-24 is known to upregulate elastin and hyaluronic acid expression.

Dusting Analysis
While certain oligopeptides, such as Oligopeptide-20, have demonstrated efficacy at low concentrations (e.g., 0.003% w/w), specific effective concentration ranges for OLIGOPEPTIDE-155 are not available in the current research. This lack of specific data makes it challenging to identify a precise dusting threshold for this particular ingredient.
The Formula
Formulation
Stability
Peptides generally exhibit optimal solubility in aqueous solutions at near-neutral pH, typically between 6-8. Careful pH selection during formulation is critical for stability. Oligopeptides containing sulfur amino acids (e.g., methionine, cysteine) are prone to oxidation and oligomerization, which can be mitigated by reducing agents and an inert atmosphere. To preserve activity, microbial contamination must be avoided. For related oligopeptides, such as Oligopeptide-20 and Oligopeptide-10, incorporation at the final stage of formulation and at temperatures below 35-40 °C and 45 °C respectively, is recommended.
Safety
Safety Profile
Specific safety assessments for OLIGOPEPTIDE-155 are currently unavailable. However, other oligopeptides within the class, such as Oligopeptide-20 and Oligopeptide-10, have been evaluated as non-irritating, non-cytotoxic, non-mutagenic, and non-sensitizing in independent studies and patch tests. Conversely, sh-oligopeptide-1 (EGF) is noted to have unknown long-term risks, highlighting the importance of specific data for each peptide.

Verdict
While oligopeptides as a class show promising benefits for skin rejuvenation and hydration, specific clinical efficacy and safety data for OLIGOPEPTIDE-155 itself are currently insufficient for a definitive assessment.
