Chemical Peels

A professional treatment that applies a carefully formulated acid solution to the skin surface to remove damaged outer layers, improve texture and tone, and stimulate the growth of fresher, healthier skin beneath.

What Are Chemical Peels?

A chemical peel is a professional skin treatment that involves applying an acid-based solution to the skin for a controlled period of time. The acid works by loosening and dissolving the bonds that hold dead and damaged skin cells on the surface, allowing them to shed away and revealing the newer, healthier skin beneath. Depending on the strength of the solution used and how long it is left on the skin, a peel can work at the surface level only or penetrate into the deeper layers of the skin for more significant results.

Chemical peels are broadly divided into three depths. Superficial peels work on the very outer layer of the skin and are the gentlest option, producing a mild improvement in texture, brightness, and tone with minimal downtime. Medium-depth peels penetrate further into the skin, producing more significant improvement in pigmentation, fine lines, and surface quality but requiring a more noticeable recovery period. Deep peels reach the deepest layers and produce the most dramatic results, but involve significant downtime and are performed less commonly in standard aesthetic clinic settings.

The acids most commonly used in professional peels include glycolic acid and lactic acid for surface brightening and exfoliation; salicylic acid for oily and acne-prone skin; trichloroacetic acid, known as TCA, for medium-depth work targeting pigmentation and lines; and a combination known as the Jessner peel, which blends several acids for a targeted result. The choice of peel depends on the skin concern being addressed, the individual skin type, and the level of downtime that is acceptable.

What to Expect

The experience of a chemical peel varies with the type and strength of the treatment. Before any peel is applied, the skin is thoroughly cleansed to remove oils and product residue that could affect how the acid absorbs. The peel solution is then applied to the skin, often with a brush or gauze.

During the treatment, a tingling, warming, or stinging sensation is normal and expected. The intensity of this sensation increases with the strength of the peel. Most superficial peels are well tolerated without any numbing, while stronger treatments may be preceded by a topical anaesthetic to improve comfort. The solution is left on the skin for a controlled period and then either neutralised with a specific solution or, in the case of some acids, left to self-neutralise.

After a superficial peel, the skin may appear slightly pink and feel tight for a day or two, with light flaking over the following days. After a medium-depth peel, more noticeable peeling and redness is expected, typically lasting five to seven days, and the skin needs careful protection and gentle care during this period. The new skin that emerges is typically smoother, brighter, and more even in tone than before.

Who It’s For and Results

Chemical peels are suitable for a wide range of skin concerns including dullness and uneven texture, mild to moderate pigmentation and sun damage, acne and post-acne marks, fine lines, and enlarged pores. The most appropriate type of peel depends on the specific concern, the skin type, and how much downtime is acceptable.

Superficial peels are suitable for most skin types, including those relatively new to professional treatments, and can be performed regularly as part of an ongoing skin maintenance programme. Medium and deeper peels are more selective in their use and require a more thorough assessment to ensure the skin is prepared and the individual is a suitable candidate.

For those with darker skin tones, the choice of peel requires particular care. Some peels carry a higher risk of causing post-inflammatory pigmentation in deeper skin tones, so a qualified provider should select the acid type and concentration carefully and may recommend a period of preparatory skincare before treatment. With the right approach, chemical peels can be safe and effective across all skin tones.

Frequently Asked Questions: Chemical Peels

This varies considerably depending on the depth and type of peel. After a superficial peel, visible peeling is often minimal, sometimes just a light flakiness over a few days that many people do not find particularly noticeable. After a medium-depth peel, the skin typically peels more noticeably, with larger sheets of skin shedding over around five to seven days. It is important not to pull or pick at peeling skin, as this can damage the new skin beneath and increase the risk of scarring or pigmentation. The peeling is a sign of the process working, not a cause for concern.

This depends on the depth of the peel and the concern being treated. Superficial peels are typically performed as a course of four to six treatments spaced two to four weeks apart, with ongoing maintenance treatments afterwards. A single medium-depth peel can produce significant improvement in one session, though multiple treatments may be recommended for more severe concerns. A provider will recommend the most appropriate programme based on the individual skin type and goals.

It is essential. A chemical peel temporarily removes the protective outer layer of the skin, making it more vulnerable to UV damage than usual. UV exposure in the weeks following a peel can lead to post-inflammatory pigmentation that is difficult to reverse and that directly undermines the improvement the peel was designed to achieve. Broad-spectrum SPF should be applied every morning without exception during the recovery period and beyond, on both sunny and overcast days and when spending time near windows indoors.

Consumer peel products are available for home use, but they contain much lower concentrations of acid than professional treatments and produce more modest results. Professional peels are significantly stronger, applied by trained practitioners who can assess the skin response and make adjustments during treatment. Home peel products can be a useful complement to a professional skincare routine but are not a substitute for clinical treatment when meaningful improvement in significant concerns is the goal. Using acids at home without proper guidance also carries a risk of over-exfoliation and barrier damage, particularly if multiple active products are being used simultaneously.
