Milt Extract

Milt extract is a polynucleotide derived from salmon milt—the reproductive gland of male salmon. It contains naturally occurring nucleotides and proteins that have been studied for their skin-conditioning properties in cosmetic formulations.In skincare products, milt extract functions primarily as a skin conditioning agent, working to support the skin's hydration and structural integrity. It is typically incorporated into formulations intended to maintain or enhance skin firmness and elasticity.

Milt extract appears to function through its polynucleotide and protein composition, which can interact with skin cells to support natural conditioning processes. These molecules are thought to encourage the skin's intrinsic repair and maintenance mechanisms.The extract may also support collagen organisation within the dermis, potentially contributing to improved skin texture and a firmer appearance over time, though the precise mechanisms in human skin are not fully characterised.

Milt extract is typically found in serums, creams and targeted treatments. Use as directed on the product label. There is no established evidence that alternating use or cycling is necessary, so consistent daily application as part of your routine is generally appropriate.

Milt extract is generally well-tolerated by most skin types. As with any new ingredient, perform a patch test if you have known sensitivities, particularly if you have fish allergies.
