Licochalcone A in Serum for Oily Skin: Interaction with Formula Oil
Question
Regarding using Licochalcone A in a serum formulation intended for oily skin:
Does Licochalcone A interact with or absorb the oil present in the serum formulation? Will the presence of oil in the formula affect Licochalcone A's property of reducing skin oiliness, which works through 5-alpha reductase inhibition?
Answer
Regarding your question about Licochalcone A and its interaction with oils in a serum formulation:
Licochalcone A works by reducing the skin's own oil production through the inhibition of 5-alpha reductase. It does not absorb or interact with the oils present in your serum formulation.
Therefore, Licochalcone A will not reduce the oil in the serum, bind to it, or lose its property of reducing skin oiliness due to the presence of oil in the formula.
However, as the goal is to reduce skin oiliness, it is advisable that other components in the serum formulation do not add excessive oil to the skin, especially since the skin is already oily.
