Lactic Acid / Glycolic Acid / Salicylic Acid

Chemical exfoliants that improve texture, tone, and clarity while supporting barrier-friendly skincare

What Are These Acids?

Chemical exfoliants are active ingredients that accelerate the removal of dead skin cells, promoting smoother, brighter, and healthier-looking skin.

The three most common types in skincare:

  1. Lactic Acid – An alpha-hydroxy acid (AHA) derived from milk or fermentation. Gentle and hydrating.
  2. Glycolic Acid – An AHA derived from sugarcane. Smallest molecular size, penetrates quickly for visible exfoliation.
  3. Salicylic Acid – A beta-hydroxy acid (BHA) derived from willow bark. Oil-soluble, targets clogged pores and excess sebum.

Each has a unique role but all share the goal of supporting cell turnover and maintaining smoother, healthier skin.

How These Acids Work in Skincare

Lactic Acid (AHA)

  • Water-soluble: Works on the surface to gently exfoliate dead skin cells
  • Hydrating properties: Helps skin retain moisture
  • Ideal for sensitive or dry skin needing gentle exfoliation

Glycolic Acid (AHA)

  • Small molecular size: Penetrates deeper for effective exfoliation
  • Improves skin texture, brightness, and fine lines
  • Best for uneven tone, dullness, and early signs of aging

Salicylic Acid (BHA)

  • Oil-soluble: Penetrates pores to exfoliate inside
  • Reduces clogged pores, blackheads, and breakouts
  • Ideal for oily or acne-prone skin

Skin Benefits of These Acids

  1. Exfoliation and Texture Improvement
    • Removes dead skin cells
    • Smooths rough or uneven skin
    • Supports brighter, more radiant skin
  2. Pore-Clarifying and Oil Control
    • Salicylic acid reduces sebum and congestion
    • Helps prevent breakouts and blackheads
  3. Supports Barrier-Friendly Aging
    • Lactic acid gently exfoliates without over-stripping
    • Glycolic acid encourages subtle collagen support
    • Helps maintain skin resilience when used correctly
  4. Enhanced Absorption of Other Actives
    • Prepares skin for hydrators, antioxidants, or brightening agents
    • Improves overall product efficacy

Who Should Use Chemical Exfoliants?

Best for:

  • Dull or uneven skin
  • Textural irregularities or fine lines
  • Oily, combination, or acne-prone skin (for BHA specifically)
  • Skin needing improved tone or clarity

Use with caution if:

  • Skin barrier is compromised
  • You have highly reactive or sensitive skin
  • Overuse can cause irritation or redness

Pro Tip: Always follow chemical exfoliation with broad-spectrum sunscreen, as skin becomes more sensitive to UV exposure.
