Double Hyaluron Liquid Application

Regarding your question about applying Double Hyaluron Liquid directly to the face without mixing:

Double Hyaluron Liquid is a concentrated ingredient (5% Hyaluronic Acid) designed to be mixed into cosmetic formulations such as serums, gels, lotions, or creams at a recommended usage rate of 1-20%. Applying concentrated ingredients directly to the skin is generally not advised as it may not provide optimal benefits and could potentially cause irritation.

It is best to use Double Hyaluron Liquid by incorporating it into a suitable base or formulation as intended.
