2,5-Dihydroxybenzoyl Dipeptide-48

2,5-Dihydroxybenzoyl Dipeptide-48 is a synthetic peptide compound designed to function as a skin conditioning and protective agent. It combines a small peptide structure with a dihydroxybenzoyl moiety, creating a molecule that can work at the skin's surface to improve moisture retention and skin feel.

In formulations, this ingredient is typically used for its humectant and emollient properties—meaning it helps skin absorb and retain water whilst providing a smooth, conditioned texture.

As a humectant, this ingredient works by drawing water from the environment and deeper skin layers to the stratum corneum (outer layer), where it helps bind moisture and prevent transepidermal water loss. The peptide component may also interact with skin proteins to support conditioning and protective functions at the cellular level.

The dihydroxybenzoyl structure likely contributes antioxidant properties, though the overall mechanism in skincare formulations remains an area of ongoing interest in cosmetic chemistry.

This ingredient is typically found in serums, moisturisers, and hydrating treatments where it works well alongside other humectants like glycerol or hyaluronic acid. It can be used daily as part of your routine. For best results, apply to damp skin so the humectant can draw moisture in, then follow with an occlusive moisturiser if your skin is very dry.
