Both glycolic and lactic peels are alpha hydroxy acid (AHA) treatments that exfoliate the skin to improve texture, tone, and radiance. However, they differ in their strength, target concerns, and suitability for various skin types. Here's a detailed comparison:

1. Source and Composition

• Glycolic Peel:

  • Derived from sugarcane.
  • Has the smallest molecular size among AHAs, allowing it to penetrate deeply into the skin.
  • Offers strong exfoliation and rejuvenation.

• Lactic Peel:

  • Derived from milk or fermented plants.
  • Has a larger molecular size, making it gentler and more surface-focused.
  • Provides exfoliation and hydration.

    4. Hydration Effects

  • Glycolic Peel:

    • Primarily exfoliates and stimulates collagen production but does not have significant hydrating effects.

    5. Suitability for Skin Types

  • Glycolic Peel:

    • Best for normal, combination, or oily skin.
    • Not ideal for highly sensitive or rosacea-prone skin due to its intensity.

  • Lactic Peel:

    • Gentle enough for sensitive, dry, or rosacea-prone skin.
    • A good starting point for individuals new to chemical peels.

    6. Potential Side Effects

  • Glycolic Peel:

    • May cause redness, tingling, or peeling, especially in sensitive skin.
    • Requires proper aftercare and sun protection.

  • Lactic Peel:

    • Offers a subtle glow and smoother texture.
    • Little to no downtime, with immediate radiance.

    8. Frequency of Use

  • Glycolic Peel:

    • Every 3-4 weeks for professional treatments.
    • At-home products may be used weekly, depending on concentration.

  • Lactic Peel:

    • Can be used more frequently (every 2-3 weeks) due to its gentle nature.
