Production process of composite middle-layer acid for promoting generation of collagen and elastin

The invention relates to the field of acid production, and discloses a production process of composite middle-layer acid for promoting generation of collagen and elastin. The composite middle-layer acid comprises the following components: 5-7% of lactic acid, 11-13% of glycolic acid, 4-6% of tartaric acid, 5-8% of mandelic acid, 2-3% of hyaluronic acid, 4-7% of malic acid, 13-16% of an aloe concentrated solution, 10-12% of pearl powder, 18-22% of trichloroacetic acid, 20-22% of phenol and 5-6% of deionized water; the production process comprises the following steps: Step 1: adding deionized water into a reaction kettle according to a ratio, heating to 70-75 DEG C, adding hyaluronic acid and malic acid according to a ratio, stirring and mixing for 30 minutes at a rotating speed of 1250 r/min, and keeping the temperature and standing for 10-15 minutes to obtain a mixture A. During production, multiple acids are compounded, and an aloe concentrated solution is taken as a slow-release agent, so that the overall s
