Area of Science:

  • Dermatology
  • Cosmetic Procedures
  • Chemical Peels

Background:

  • Trichloroacetic acid (TCA) peels are widely used for skin issues but outcomes vary.
  • Existing TCA peel methods lack standardization, leading to inconsistent results based on physician skill and patient management.

Purpose of the Study:

  • To develop a standardized TCA peel method for a depth between superficial and medium peels.
  • To define peel depth using intraoperative clinical signs and a color guide for even application.
  • To minimize variables affecting TCA peel outcomes.

Main Methods:

  • A standardized coating system using specific TCA concentrations (15% or 20%) and volumes.
  • Application of multiple TCA coats to target the epidermis, papillary dermis, or upper reticular dermis.

  • Utilizing clinical signs (frost, color, epidermal sliding) to guide depth and correlate with healing (7-10 days).

    • Main Results:

    • The TCA Blue Peel provides a simple, consistent treatment for epidermal and dermal skin concerns.
    • Achieved consistent depth control correlating with clinical signs and healing time.
    • Observed unexpected skin tightening and reduced laxity, suggesting the role of papillary and upper reticular dermis.

    Conclusions:

    • A depth-controlled TCA peel system using a coating method and clinical signs is presented.
    • This standardized approach simplifies TCA peels for all skin types and non-facial areas.
    • The method expands treatment options for patients previously excluded from deeper peels.
