Understanding Hydroxy Acids: AHAs & BHAs Defined

n

Hydroxy acids are a class of exfoliating compounds widely used in anti-aging skincare. The two main types are:

n
• Alpha-Hydroxy Acids (AHAs): Water-soluble acids, typically derived from plants and dairy, that work on the skin’s outermost layers.

n

• Beta-Hydroxy Acids (BHAs): Oil-soluble acids, often derived from willow bark, that penetrate deeper into pores and address oil-related concerns.

n

n

Both AHAs and BHAs aid the skin’s exfoliation process, promoting cell turnover and revealing fresher, more vibrant skin underneath.

nn

Key Types of AHAs

n

n
• Glycolic Acid: Extracted from sugar cane; has the smallest molecule, allowing deep penetration and potent effects for resurfacing.

n

• Lactic Acid: Sourced from lactose and fermented vegetables; less irritating, ideal for sensitive or dry mature skin.

n

• Citric Acid: Derived from citrus fruits; often used for brightening and mild exfoliation.

n

Key Types of BHAs

n

n
• Salicylic Acid: The standard and most widely used BHA, famous for its ability to unclog pores and reduce inflammation.

n

nn

How Aging and Sun Damage Affect Skin

n

Aging, whether chronological or hastened by photoaging (sun damage), manifests through a range of visible changes:

n

n
• Loss of collagen and elastin, leading to fine lines and wrinkles

n

• Hyperpigmentation, such as age spots (lentigines) and uneven skin tone

n

• Rough or leathery texture due to slowed cell turnover

n

• Dryness and decreased capacity to retain moisture

n

• Exaggerated pores and diminished radiance

n

Photoaging accelerates the breakdown of structural proteins, aggravates pigmentation issues, and disrupts the skin barrier, making recovery and renewal slower.

nn

Alpha-Hydroxy Acids (AHAs) for Mature Skin

n

AHAs have been used for decades as anti-aging agents, with multiple clinical trials supporting their benefits for mature, sun-damaged skin.

nn

Core Benefits of AHAs

n

n
• Exfoliation: Disrupt ionic bonds between dead skin cells, promoting natural shedding and smoother texture.

n

• Wrinkle Reduction: Increase epidermal thickness, stimulate collagen production, and reduce the depth and number of wrinkles.

n

• Brightness and Even Tone: By accelerating cell turnover, AHAs fade hyperpigmentation, age spots, and discoloration.

n

• Enhanced Hydration: Boost skin’s production of natural moisturizing factors (like hyaluronic acid), restoring plumpness.

n

• Improved Elasticity and Firmness: Ongoing stimulation of collagen and elastin for a firmer facial contour.

n

nn

Most-Researched AHAs for Wrinkle and Sun Damage Repair

n

n
• Glycolic Acid: Best-documented for anti-aging; often used in concentrations from 5% for daily care to up to 20–70% in professional peels.

n

• Lactic Acid: Gentler alternative notable for its hydrating capabilities; suitable for drier or sensitive mature skin.

n

n

Regular use results in smoother texture, reduced depth and visibility of lines, and enhanced radiance. AHAs are particularly recommended for targeting surface wrinkles and diffuse sun-induced pigmentation.

nn

Best Uses for AHAs

n

n
• Daily exfoliating serums or creams (5–10% concentration)

n

• Weekly to monthly at-home or professional chemical peels (10–30% concentration or higher)

n

• Treatments for hyperpigmentation, actinic keratoses, and general skin texture refinement

n

nn

Beta-Hydroxy Acids (BHAs) for Mature Skin

n

BHAs (mainly salicylic acid) have a unique place in mature skincare, owing to their oil-soluble nature and ability to penetrate deeper into sebaceous (oil) glands.

nn

Key Benefits of BHAs

n

n
• Deep Exfoliation: Dissolve sebum and debris inside pores, effectively addressing enlarged pores and comedones.

n

• Reduction of Fine Lines: Support skin turnover, smoothing texture and softening the look of wrinkles (especially in oilier or combination mature skin).

n

• Sun Damage Support: Improve uneven tone and sun-related dullness by unclogging and clearing pores as cell turnover increases.

n

• Anti-Inflammatory & Antibacterial: Calm redness and reduce outbreaks common in mature skin experiencing hormonal shifts.

n

n

As mature skin can still be acne-prone or oily, BHAs offer crucial support against blemishes and lingering breakouts; they also enhance clarity and radiance.

nn

Best Uses for BHAs

n

n
• As leave-on exfoliant lotions and gels (1–2% concentration is most common for mature skin)

n

• Spot-treatments for sun damage, milia, or persistent clogged pores

n

• In combination with AHAs for enhanced skin renewal with texture-boosting and clarifying effects

How to Choose: Matching Acids to Skin Types and Concerns

n

n
• Dry or Sun-Damaged Mature Skin: Prefer AHAs (especially lactic or glycolic acid) for maximum hydration and wrinkle reduction.

n

• Oily or Combination Mature Skin: Add BHAs (salicylic acid) to clear pores, reduce breakouts, and improve surface smoothness.

n

• Sensitive Skin: Start with low concentrations of lactic acid (a mild AHA), patch test, and gradually increase as tolerated.

n

• Hyperpigmentation: Prioritize glycolic acid; supplement with niacinamide or vitamin C for comprehensive brightening.

n

• Comorbid Acne and Aging: Strategically combine AHA and BHA products for anti-wrinkle, anti-acne, and anti-sun damage defense.
