Glycolic acid
(Synonyms: 乙醇酸) 目录号 : GC31549
Glycolic acid (dicarbonous acid, hydroxyacetic acid, hydroacetic acid) is the smallest alpha-hydroxy acid. Due to its excellent capability to penetrate skin, glycolic acid is often used in skin care products, most often as a chemical peel. Glycolic acid is an inhibitor of tyrosinase, suppressing melanin formation and lead to a lightening of skin colour.

Cell experiment: | HM3KO pigmented human melanoma cells and B16 mouse melanoma cells are cultured in Dulbecco’s modified Eagles medium supplemented with 10%fetal calf serum and appropriate amounts of antibiotics and fungizone were dissolved at a concentration of 100mg/mL in distilled water. These chemicals (e.g., Glycolic Acid ) are added to the cell cultures at final concentrations of 300 or 500 mg/mL every 2 days for 5 days[1]. |

Effect of glycolic acid, phytic acid, soothing complex containing Emulsion on Hyperpigmentation and skin luminosity: A clinical evaluation
Background: Improvement in skin luminosity and dyschromia such as postinflammatory hyperpigmentation (PIH) and actinic photodamage are leading causes for cosmetic consultation. Formulation of topical at home treatment is challenging, using a range of modalities, to help hinder or prevent inflammatory mediators without further irritating the skin. Glycolic acid is a known antioxidant; in various free acid levels, it has been introduced as a topical therapy aimed at reducing pigmentation and improving skin texture, tone, and luminosity. Methods: In a 12-week clinical study, a novel, topical facial emulsion containing 10% glycolic acid, 2% phytic acid, and soothing complex in emulsion was evaluated for its effectiveness in treating skin quality in American female volunteers with Fitzpatrick skin types II-VI. Efficacy evaluations were performed at pretreatment baseline, weeks 2, 4, 8, and 12, and included expert clinical grading, and self-assessment questionnaires. Cutaneous tolerability was also evaluated by assessing subjective and objective irritation of the treatment area. Results: Significant improvement in the appearance of skin PIH, hyperpigmentation, texture, and tone homogeneity was observed beginning at week 4 and continued through week 12. Conclusions: The findings suggest that the test product is well suited for at-home skincare. It was both well-tolerated and an effective treatment option for addressing hyperpigmentation and overall skin luminosity.
Basic chemical peeling: Superficial and medium-depth peels
Chemical peeling, or chemexfoliation, has been used for centuries to improve signs of ultraviolet light-induced sun damage. Over the last 30 years, the science behind chemical peeling has evolved, increasing our understanding of the role of peeling ingredients and treatment indications. The depth of peels is directly related to improved results and to the number of complications that can occur. Key principles for superficial and medium depth peeling are discussed, as well as appropriate indications for these treatments.
Comparative Evaluation of Efficacy and Tolerability of Glycolic Acid, Salicylic Mandelic Acid, and Phytic Acid Combination Peels in Melasma
Background: Melasma is acquired symmetric hypermelanosis characterized by light-to-deep brown pigmentation over cheeks, forehead, upper lip, and nose. Treatment of this condition is difficult and associated with high recurrence rates. Chemical peels have become a popular modality in the treatment of melasma.
Objective: To compare the therapeutic efficacy and tolerability of glycolic acid (35%) versus salicylic-mandelic (SM) acid (20% salicylic/10% mandelic acid) versus phytic combination peels in Indian patients with melasma.
Materials and methods: Ninety patients diagnosed with melasma were randomly assigned into 3 groups of 30 patients each. Group A received glycolic acid (GA-35%) peel, Group B received SM acid, and Group C received phytic combination peels. Each group was primed with 4% hydroquinone and 0.05% tretinoin cream for 4 weeks before treatment. Chemical peeling was done after every 14 days in all groups until 12 weeks. Clinical evaluation using melasma area and severity index (MASI) score and photography was recorded at every visit and follow-up was done until 20 weeks.
Results: There was a decrease in MASI score in all 3 groups but it was statistically significantly lower in Group A than Group C (p = .00), and it was also statistically significantly lower in Group B than Group C (p = .00) but there was no statistically significant difference between Groups A and B (p = .876). Objective response to treatment evaluated by reduction in MASI scoring after 12 weeks was 62.36% reduction in GA group, 60.98% reduction in SM group, and 44.71% in phytic acid group.
Conclusion: It is concluded that GA (35%) and SM acid peels are both equally efficacious and a safe treatment modality for melasma in Indian skin, and are more effective than phytic acid peels. Salicylic-mandelic peels are better tolerated and more suitable for Indian skin.
Ethylene glycol and glycolic acid production by wild-type Escherichia coli
Ethylene glycol and glycolic acid are bulk chemicals with a broad range of applications. The ethylene glycol and glycolic acid biosynthesis pathways have been produced by microorganisms and used as a biological route for their production. Unlike the methods that use xylose or glucose as carbon sources, xylonic acid was used as a carbon source to produce ethylene glycol and glycolic acid in this study. Amounts of 4.2 g/L of ethylene glycol and 0.7 g/L of glycolic acid were produced by a wild-type Escherichia coli W3110 within 10 H of cultivation with a substrate conversion ratio of 0.5 mol/mol. Furthermore, E. coli strains that produce solely ethylene glycol or glycolic acid were constructed. 10.3 g/L of glycolic acid was produced by E. coli ΔyqhD+aldA, and the achieved conversion ratio was 0.56 mol/mol. Similarly, the E. coli ΔaldA+yqhD produced 8.0 g/L of ethylene glycol with a conversion ratio of 0.71 mol/mol. Ethylene glycol and glycolic acid production by E. coli on xylonic acid as a carbon source provides new information on the biosynthesis pathway of these products and opens a novel way of biomass utilization.
