The invention discloses a herbal compound anti-wrinkle spot-fading moisturizing mask and a preparation method thereof, and relates to the technical field of cosmetic processing. The herbal compound anti-wrinkle spot-fading moisturizing mask is composed of essence and two-phase permeation antibacterial film cloth, the essence is prepared from a proteoglycan protein peptide nanocomposite, synergistic liposome, a lucid ganoderma extract, a rhodiola rosea extract, a ginseng extract, a semen cuscutae extract, glycerin, hydroxyethyl cellulose, p-hydroxyacetophenone and deionized water. The essence is loaded in the biphasic permeation antibacterial film cloth, fat-soluble and water-soluble active substances in the essence can permeate and immerse into skin through gradient permeation and multistage pore channels, the permeability of the active substances is improved, and under further delivery of nano-particles and lipidosome, the synergistic skin care effect of multiple components is remarkably improved; the anti-wrinkle, freckle-fading and moisturizing effects are effectively improved, and meanwhile, the anti-wrinkle, freckle-fading and moisturizing composition has excellent antibacterial property and can reduce skin sensitivity and inflammatory response.

This invention relates to the field of acyclic or carbocyclic compounds and discloses a method for preparing 6-bromo-2,3-difluorotrifluorotoluene, comprising: dissolving 2,3-difluorotrifluorotoluene in a mixed solvent composed of a polar modifier containing a proton acceptor site and a nonpolar solvent; adding a polyether stabilizer and an iron-based catalyst; and dropwise adding liquid bromine to trigger a directional bromination reaction. The method utilizes the protonated ion-pair complex formed by the in-situ generation of hydrogen bromide and the polar modifier, which, in conjunction with the polyether stabilizer, constructs a sterically hindered shielding structure at positions 4 and 5 of the substrate molecule. This invention forces the electrophilic substitution pathway to be directed towards position 6 of the substrate molecule, overcoming the bottleneck of extremely low positioning accuracy in passivated aromatic ring systems, transforming disordered isomers into a single dominant isomer, thereby reducing separation energy consumption.

This invention discloses a polyacid-based mild acne-removing composition, its preparation method, and its application, belonging to the field of acne treatment preparation technology. By mass percentage, the polyacid-based mild acne-removing composition comprises 1%–10% bee venom peptide, 0.25%–5% microcapsules containing polydeoxyribonucleotides, 0.2%–1.5% soothing active ingredients, 0.5%–3% biosaccharide gum-1, 0.2%–2% biosaccharide gum-2, 0.05%–0.5% astragalus gum, 0.1%–1% pH buffering compound, 2%–10% acid mixture, and 3%–20% alcohol mixture, with the balance being water. This acne-removing composition achieved a low-irritation user experience with a high-concentration polyacid formula in subjects with sensitive, mild to moderate facial acne, effectively improving the problems of poor tolerance and limited applicability of traditional acid-based acne products for sensitive skin, significantly broadening the applicable skin types and application scenarios for high-efficacy acid-based acne products, and balancing effective acne removal with safety suitable for sensitive skin.
