Hello,
Dissolving method (Anhydrous) Is there a way to recommend that the texture of the serum is not heavy? When applied to the skin, it does not leave a greasy feeling. or too heavy to make the serum texture more light Is it easier to absorb? Between Silicone base (Kielh's) and Glycols base (SkinCeuticals), what are the advantages and disadvantages?
silicone base will give softness and lightness more than light glycol. More gooey, but "maybe" can help.
Vitamin C (L-ascorbic acid) is better absorbed into the skin because glycol can help dissolve
Vitamin C (L-ascorbic acid) partially obtained (the solubility rate was about 5% compared to water is more than 30%), silicone base can prevent oxidation of
L-ascorbic acid is better than glycol base due to silicone having water- repellent while glycol can attract water (humectant)
PS. If there is a solution in the formula
L-ascorbic acid in water, will it cause oxidation and deterioration
?
