Chemical Peel Types Explained — Light, Medium, Deep (Adelaide)

Chemical peels are grouped by depth. Light (superficial) peels such as glycolic, lactic, mandelic or salicylic acid work on the surface, usually with little visible peeling. Medium-depth peels go further and can mean a week or more of recovery. Which peel, if any, suits you depends on your skin concern and type, assessed at a consultation.

“Chemical peel” covers a broad family of treatments at different depths using different active ingredients. The same name can mean a light surface peel with little visible peeling or a medium-depth peel with a week or more of recovery. Working out which peel, if any, suits your skin concern is the job of the consultation.

The three depth categories

Light peels

Active ingredients: alpha-hydroxy acids (glycolic, lactic, mandelic), beta-hydroxy acid (salicylic), enzyme-based peels.

Depth: the outermost layer of skin.

Recovery: often mild flaking for a few days; some people have none. Recovery varies; your practitioner will explain what to expect.

Often used for: dullness, mild pigmentation, mild acne, maintenance between other treatments.

Adelaide pricing: $120–$250 per session; a light course (4–6 sessions) $400–$900.

Medium-depth peels

Active ingredients: TCA (trichloroacetic acid), Jessner’s solution, modified TCA blends.

Depth: into the upper dermis.

Recovery: visible peeling for around a week is common, and skin stays sun-sensitive for several weeks.

Often used for: moderate pigmentation, fine lines, mild acne scarring, sun damage, and melasma (with caution).

Adelaide pricing: $300–$600 per session.

Deep peels

Active ingredients: high-strength TCA, phenol peels.

Depth: into the deeper dermis.

Recovery: two weeks or more, with significant risks.

Note: uncommon outside specialist medical practices and reserved for specific situations after careful assessment.

Active ingredients in plain English

Glycolic acid (alpha-hydroxy) — a small molecule that penetrates more readily than other AHAs at the same strength. Used for dullness, sun damage and fine lines. Practitioners are often more cautious with it on darker skin types.

Lactic acid (alpha-hydroxy) — milder than glycolic, with a hydrating effect. Often used for sensitive skin or as an introduction to peels.

Mandelic acid (alpha-hydroxy) — a larger molecule that penetrates more slowly. Often chosen for darker skin types and for pigmentation in skin that doesn’t tolerate glycolic well.

Salicylic acid (beta-hydroxy) — oil-soluble, so it works within pores. Often used for acne, oily skin and congestion.

TCA (trichloroacetic acid) — the common medium-depth peel agent. Concentration and application technique determine depth, and the practitioner should explain both.

Jessner’s solution — a combination of salicylic acid, lactic acid and resorcinol. Sometimes used before TCA for a deeper effect, or on its own as a light-to-medium peel.

Adelaide-specific considerations

Sun protection strongly affects how peeled skin heals. Adelaide’s UV is high to extreme through summer, so strict SPF 50+, a hat and shade are needed for several weeks after any medium-depth peel — and daily SPF as a habit afterwards.

Skin type matters as much as peel type. Darker skin treated with the wrong peel or strength can develop pigment change. A careful practitioner assesses your skin type at consultation.

Seasonal timing — many Adelaide practitioners suggest planning medium-depth peels for March–September rather than high-UV summer. Ask about timing.

Combination approaches

Peels are sometimes combined with:

• Skin needling — alternated with peels as part of a planned course
• LED light therapy — sometimes offered alongside peels
• Home skincare — such as vitamin C and niacinamide between sessions, plus any medical treatments your GP or dermatologist may discuss

Risks and suitability

Peels can cause redness, stinging, prolonged peeling, cold-sore flare-ups, infection, pigment change (darker or lighter patches) and, rarely, scarring — with risk increasing with depth. Peels may not be suitable during pregnancy, with active skin infections or eczema, after recent use of certain acne medicines, or with a history of keloid scarring. Tell your practitioner about all medicines and skincare you use. Recovery varies; your practitioner will explain what to expect.

Before you book

• If the person treating you is a registered health practitioner, check their registration on the Ahpra public register and ask what type of registration they hold. Ask what training the person performing the peel has.
• Ask about all your options, including skincare, other treatments and doing nothing.
• Ask for the full cost, including any course of sessions, in writing.
• Take time to think — you don’t need to decide on the day.
• Cosmetic consultations are for adults (18+).

Frequently asked questions

What's the difference between a light and a medium-depth peel?

A light peel works on the outermost layers and usually involves mild redness and flaking. A medium-depth peel reaches further into the skin, often involves visible peeling for a week or more and carries more risk of pigment change. Recovery varies with the peel and your skin.

How much does a chemical peel cost in Adelaide?

Indicative Adelaide ranges are $120–$250 per session for a light peel, $400–$900 for a light-peel course of 4–6 sessions, and $300–$600 per session for a medium-depth peel. Your cost is confirmed in writing after assessment.

Which peel is best for pigmentation or acne?

It depends on the cause and your skin type. Salicylic acid is often discussed for oily or congested skin, and mandelic acid for medium to darker skin types. Some pigmentation, such as melasma, needs a cautious, combined approach. Your practitioner will assess you first.

Are chemical peels suitable for darker skin?

Some are, with caution. Darker skin types have a higher risk of pigment change after deeper or more aggressive peels, so lighter peels, test patches and careful preparation are often discussed. A skin-type assessment should come first.
