Summary
Hydroxyacids, including alpha-hydroxyacids and newer polyhydroxy/bionic acids, offer significant skin benefits. These compounds are widely used in cosmetics and therapeutics for antiaging, acne, and sensitive skin treatments.
Area of Science:
- Dermatology
- Cosmeceutical Science
Background:
- Hydroxyacids encompass alpha-hydroxyacids (AHAs), beta-hydroxyacids, polyhydroxy acids (PHAs), and bionic acids.
- These compounds are extensively utilized in cosmetic and therapeutic formulations for skin benefits.
Purpose of the Study:
- To review the diverse benefits and applications of hydroxyacids in skincare.
- To highlight the advantages of newer PHAs and bionic acids, particularly for sensitive skin and antiaging.
Main Methods:
- Literature review of hydroxyacid classifications and their established uses.
- Analysis of the chemical properties and biological effects of different hydroxyacid types.
Main Results:
- Glycolic acid (an AHA) is common in antiaging, moisturizing, peels, and treatments for hyperpigmentation and acne.
- PHAs and bionic acids provide AHA benefits with reduced irritation, suitable for sensitive skin, rosacea, and post-procedure care.
- Bionic acids offer antioxidant, barrier-strengthening, moisturizing, and matrix metalloproteinase inhibitory effects for preventative antiaging.
Conclusions:
- Hydroxyacids offer versatile skin benefits and are integral to modern cosmeceuticals.
- PHAs and bionic acids represent advancements, offering efficacy with improved tolerability.
- Combining hydroxyacids with other treatments enhances therapeutic outcomes and patient tolerance.

01:41Reactions of Carboxylic Acids: Introduction
Carboxylic acids possess an acidic –COOH functional group. The acidity can be attributed to the resonance stabilization of their conjugate base, wherein the negative charge is delocalized over both oxygen atoms.
01:01Acid Halides to Carboxylic Acids: Hydrolysis
Hydrolysis of acid halides is a nucleophilic acyl substitution reaction in which acid halides react with water to give carboxylic acids. The reaction occurs readily and does not require acid or a base catalyst.
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic acid...

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:15Carboxylic Acid Derivatives: Overview
Carboxylic acid derivatives are formed by replacing the hydroxyl group of carboxylic acids with a different functional group. The most common carboxylic acid derivatives are:
01:13Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
Hydrolysis of esters under acidic conditions proceeds through a nucleophilic acyl substitution. In the presence of excess water, the reaction proceeds in a reversible manner, forming carboxylic acids and alcohols.
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...

01:31Physical Properties of Carboxylic Acids
Carboxylic acids with lower molecular weight exhibit a sharp and unpleasant odor. They also have higher boiling and melting points than analogous compounds, such as aldehydes, ketones, and alcohols.
