Our lead clinician explains the different peel depths, their specific indications, and what the latest peer-reviewed research tells us about long-term skin rejuvenation.

What is a Chemical Peel?

A chemical peel is a controlled application of a chemical solution to the skin, which causes the outermost layers to exfoliate and eventually peel away, revealing fresher, more even-toned skin beneath.

The Three Depths of Peels

Superficial Peels

Using alpha-hydroxy acids (AHAs) like glycolic or lactic acid. These target only the epidermis, ideal for mild discolouration, rough texture, and a general glow boost. No downtime.

Medium Peels

Typically using trichloroacetic acid (TCA). These penetrate into the upper dermis, addressing moderate sun damage, deeper wrinkles, and acne scarring. Expect 5–7 days of peeling.

Deep Peels

Using phenol, these reach the mid-dermis for dramatic results on severe sun damage and deep wrinkles. Reserved for specific candidates and requires significant recovery.

Who Benefits Most?

Chemical peels are incredibly versatile. At Plus Life, we use them to treat: pigmentation & melasma, acne scars, fine lines, and uneven skin texture.

The key is personalisation. A peel that is right for one patient may be wrong for another. We always assess before we act.
