Glycolic Acid Micro Peel Facial Protocol

For optimal results and safety, glycolic acid micro peel facials should use concentrations of 30-50% for very superficial peels applied for 1-2 minutes, or 50-70% for superficial peels applied for 2-5 minutes, administered once every 15 days for a treatment duration of 4-6 months. 1

Concentration and Application Guidelines

Pre-Treatment Protocol

  • Cleanse the skin thoroughly before application
  • Consider skin preparation with topical tretinoin or low-concentration glycolic acid (10-15%) for several weeks prior to professional peels 1, 2
  • Degrease the skin immediately before application 2
  • Assess skin type and condition to determine appropriate concentration

Treatment Protocol Based on Depth

  1. Very Superficial Peel

    • 30-50% glycolic acid
    • Application time: 1-2 minutes
    • Ideal for mild skin concerns and first-time patients 1
  2. Superficial Peel

    • 50-70% glycolic acid
    • Application time: 2-5 minutes
    • For moderate skin concerns 1
  3. Medium Depth Peel

    • 70% glycolic acid
    • Application time: 3-15 minutes
    • For more significant skin concerns 1

Application Technique

  • Apply evenly using gauze or applicator brush
  • Monitor skin reaction closely during application
  • Neutralize the acid after the specified time with a neutralizing solution (typically sodium bicarbonate) 2, 3
  • Rinse thoroughly with cool water

Treatment Schedule and Duration

  • Professional treatments: Once every 15 days
  • Recommended course: 4-6 months (approximately 8-12 sessions) 1
  • For acne treatment: 3-4 sessions may be sufficient for visible improvement 4, 5

Indications

  • Acne vulgaris and acne scars 6, 1
  • Fine wrinkles and photoaging 4
  • Melasma and post-inflammatory hyperpigmentation 3
  • Skin texture improvement 5

Contraindications

  • Lack of psychological stability or unrealistic expectations
  • Poor general health or nutritional status
  • Isotretinoin therapy within the last 6 months
  • Active infection or open wounds (herpes simplex, excoriations, open acne cysts)
  • History of abnormal scarring or delayed wound healing
  • History of therapeutic radiation exposure
  • Active dermatitis conditions (rosacea, seborrheic, atopic, psoriasis) 6, 1

Post-Treatment Care

  • Apply gentle moisturizer after treatment
  • Mandatory daily sunscreen use (glycolic acid increases photosensitivity)
  • Avoid sun exposure for at least one week after treatment
  • Continue with home care using lower concentration glycolic acid products (10-15%) between professional treatments 1, 7

Potential Adverse Effects

  • Mild stinging, discomfort, and erythema (common and expected)
  • Post-inflammatory hyperpigmentation (more common in darker skin types)
  • Erosive blisters and scarring (with improper technique or higher concentrations)
  • Increased sun sensitivity 1

Special Considerations

  • Safe for Fitzpatrick skin types I-IV with proper technique 3
  • For darker skin types (IV-VI), consider starting with lower concentrations and shorter application times to reduce risk of post-inflammatory hyperpigmentation
  • Can be combined with microneedling for enhanced treatment of acne scars 8

By following this structured protocol, glycolic acid micro peel facials can effectively address various skin concerns while minimizing potential adverse effects.
