Emulsions are the most suitable cosmetic formulas for anti-aging products. Since senile skin is almost always alipiid, it may be appropriate to formulate formulas that have the external fat phase, but to avoid stickiness, an external phase silicone emulsion has been selected as the base formula, which can be cold-processed and can contain or not glycerin.
The selection of ingredients is a complicated task, since the offer is very broad. As a guideline, it is considered important the presence of a sunscreen and an antioxidant in the oil phase nulante, and of a free radical scavenger and an aqueous extract of regenerative activity in the aqueous phase.
