how to improve absorption of serum
I am working on a facial serum and it seems to take forever to absorb into the skin. Our customer is wanting something like a 2-in-1 serum that would eliminate the need for a moisturizer after. Maybe adding an emulsifier will help this? It feels so wet upon application and it has a slight soaping effect during rub out. What can I add to help it absorb faster? It’s also very slightly tacky. I do plan on increasing the siligel to increase viscosity as its a bit runny right now, but I think that might increase tackiness as well. Thanks!

Reduce the amount of polyols… the result will ‘dry’ faster but the serum will be less hydrating.Add silica or similar to increase surface (faster evaporation) and impart a drier, powdery feeling or replace some water with volatile liquids.More Siligel may turn it even tackier and slower to seep in. Try it out. -
your best bet is to remove or reduce the Siligel -
Off Topic…can I ask where you buy your L22? That stuff is crazy expensive whenever I find it.
I have made basically my own version with lower cost Acai sterols and Floratech’s (maker of L22) Mac Nut oil and ethyl macadamiate.

@Pharma and @Bill_Toge thanks for the recommendations, I will test those out.
@Graillotion right now I am just using samples from the supplier, although they only send such a small sample size because it is an expensive material, maybe 30 g at most. I have all of those ingredients that you mentioned so I think I’m going to try something similar. I have only been able to make a few formula variations because I’m so limited with the L22
