Chemical Peels 101: Understanding Skin Peels in Cosmetic Dermatology

Written by Dr. Maha Shariff · May 26, 2026 · Chemical Peels

Chemical peels are a well-established skin resurfacing treatment used to improve post-inflammatory hyperpigmentation, acne, uneven skin tone, and textural irregularities.

Chemical peels have been used in cosmetic dermatology for decades and are a well-established skin resurfacing treatment used to improve a range of skin concerns.

peels can help treat:

  • Post-inflammatory pigmentation (PIH)
  • Acne and congestion
  • Uneven skin tone
  • Superficial textural irregularity
  • Sun-related skin changes

Those used in clinical practice are different in strength and formulation compared with over-the-counter exfoliating products or at-home peel kits. Depending on the type of peel used, treatment may be superficial or medium-depth.

Clinically administered chemical peel

How chemical peels work

They work by creating a controlled, intentional injury within the skin, encouraging renewal and improving overall skin texture and clarity over time.

Superficial peels act mainly within the epidermis, while medium-depth peels penetrate further into the upper dermis.

Commonly used acids include:

  • Glycolic acid
  • Lactic acid
  • Salicylic acid
  • Mandelic acid
  • Trichloroacetic acid (TCA) in selected medium-depth peels

Different acids are selected according to the skin concern being treated and individual clinical assessment.

Assessment and skin preparation

Before treatment, a full assessment is essential and includes:

  • Skin type and sensitivity
  • Pigmentation risk (including risk of post-inflammatory hyperpigmentation)
  • Presence of active acne or inflammation
  • Skin barrier function
  • Previous treatment response
  • Medical history, including medications and previous skin reactions

This is important because treatment response and risk can vary significantly between individuals, particularly in patients with pigmentation-prone skin. Depending on these factors, a period of skin preparation may be recommended before treatment to optimise safety and outcomes.

How peels fit into your treatment plan

Chemical peels are often used as part of a broader treatment plan rather than as a standalone procedure. They are commonly combined with medical skincare to help maintain results and support ongoing improvement.

Treatment expectations

Chemical peels are usually performed as a series of treatments spaced approximately 4–6 weeks apart, depending on the indication being treated and the depth of peel used.

Visible improvements may include:

  • Improved skin clarity
  • More even skin tone
  • Reduced congestion
  • Smoother skin texture
  • Softening of fine lines

Some redness, dryness, or visible peeling may occur following treatment depending on peel depth and individual skin sensitivity. Results develop gradually and are usually cumulative over time rather than immediate.

Next step

If you are considering chemical peels, the first step is a clinical assessment for a detailed one-to-one discussion tailored to you, including treatment goals, options, and expected outcomes.
