I am making a serum using the Light Cream Maker base, but the texture feels a bit heavy and slow to absorb into the skin. I would like recommendations for ingredients that can provide a soft, fast-absorbing texture that is easy to spread. I am interested in LipidSoft CC and Dimethyl Isosorbide (DMI). Please advise which ingredient would be suitable or suggest other alternatives. I am also wondering if changing the base to Satin Cream Maker would be better than Light Cream Maker for a serum that contains 20% oil. I want a serum texture that is light, easy to spread, fast-absorbing, and non-sticky. Additionally, I need recommendations for ingredients to reduce thick melasma and freckles. Finally, I need a recommendation for another base that can be used with a high percentage of oil (70-80% oil) for making a serum, such as a serum based on non-sticky Fractionated Coconut Oil. Please recommend a suitable base for this purpose.
