Who are chemical peels for acne suitable for?
Chemical peels for acne are suitable for a broad range of patients experiencing acne-related skin concerns. During your consultation, your doctor will assess your skin to determine whether a peel-based approach is clinically appropriate for you. Common presentations that respond well to chemical peels include:
- Comedonal acne
Persistent blackheads (open comedones) and whiteheads (closed comedones) that do not respond to over-the-counter cleansers and exfoliants. Chemical peels dissolve the keratin plugs blocking pores, helping to clear existing comedones and prevent new ones from forming.
- Inflammatory acne
Red, tender papules and pustules caused by bacterial colonisation and inflammation within clogged pores. Peels reduce the bacterial load on the skin surface and within the follicle, while accelerating the shedding of cells that contribute to blockages.
- Post-acne marks (PIH)
Flat brown or dark marks left behind after acne lesions heal, known as post-inflammatory hyperpigmentation. Peels promote cell turnover, gradually fading discolouration and evening out skin tone over a course of treatments.
- Congested and oily skin
Skin with excessive sebum production, enlarged pores and a rough, uneven texture. Oil-soluble peels such as salicylic acid penetrate into pores to dissolve trapped sebum, reducing shine and refining the skin surface.
For a broader clinical overview of acne as a condition, including its causes and classification, see our acne condition page and acne treatment guide.
How chemical peels treat acne
Chemical peels work by applying a controlled acid solution to the skin surface. The acid dissolves the intercellular bonds (desmosomes) that hold dead skin cells together in the stratum corneum, the outermost layer of the epidermis. This controlled exfoliation triggers several mechanisms that directly address acne pathology:
- Dissolving intercellular bonds between dead skin cells, allowing them to shed more efficiently and preventing the build-up that blocks pores
- Removing the layer of dead, keratinised skin that traps sebum and bacteria within follicles, directly unclogging existing comedones
- Reducing the population of Cutibacterium acnes on the skin surface and within pores, lowering the inflammatory stimulus that drives papules and pustules
- Accelerating epidermal cell turnover, promoting the growth of fresh, healthy skin cells and reducing the time that post-acne marks remain visible
- Helping to regulate sebum production over a course of treatments, particularly with salicylic acid peels that have an affinity for the lipid-rich environment of the pore
- Improving the penetration and efficacy of topical acne treatments such as retinoids, niacinamide and benzoyl peroxide by removing the barrier of dead cells that can impede absorption
The depth and intensity of exfoliation depend on the acid type, its concentration and the duration of application. Your doctor selects these parameters based on your acne severity, skin type and sensitivity, adjusting at each session as your skin responds to treatment.
Types of chemical peels for acne
Not all chemical peels are the same, and the choice of acid is critical for achieving optimal results without unnecessary irritation. At Berkshire Aesthetics, we use a range of medical-grade peels tailored to different acne presentations and skin types. Your doctor will recommend the most appropriate peel — or combination of acids — based on your clinical assessment.
Salicylic acid (BHA) peels
Salicylic acid is a beta-hydroxy acid (BHA) and the most commonly used peel for acne-prone skin. Unlike water-soluble AHAs, salicylic acid is oil-soluble, which means it can penetrate through the sebum that lines the inside of pores. This allows it to exfoliate within the follicle itself, dissolving sebum plugs and clearing comedones from the inside out. Salicylic acid also has anti-inflammatory and mild antibacterial properties, making it particularly effective for patients with comedonal acne, oily skin and mild-to-moderate inflammatory acne. Concentrations typically range from 20% to 30% for professional-grade peels.
Glycolic acid (AHA) peels
Glycolic acid is an alpha-hydroxy acid (AHA) derived from sugar cane and has the smallest molecular size of all AHAs, allowing for deeper penetration into the epidermis. Glycolic acid peels accelerate cell turnover, improve surface texture and help fade post-acne marks (PIH) by promoting the replacement of pigmented cells with fresh, evenly toned skin. They are often used for patients whose primary concerns include uneven texture, dullness and residual discolouration alongside mild acne. Professional concentrations range from 20% to 70%, with higher concentrations reserved for more resilient skin.
Mandelic acid peels
Mandelic acid is an AHA derived from bitter almonds with a larger molecular size than glycolic acid. This larger molecule penetrates the skin more slowly and evenly, reducing the risk of irritation and making it a gentler option for patients with sensitive or reactive skin. Mandelic acid is particularly suitable for patients with darker skin tones (Fitzpatrick types IV–VI), where the risk of post-inflammatory hyperpigmentation from more aggressive peels is higher. It provides effective exfoliation and has antibacterial properties that support acne clearance.
Lactic acid peels
Lactic acid is another AHA with a larger molecular size, offering gentle exfoliation with an added hydrating effect. It stimulates ceramide production in the skin barrier, which helps maintain moisture levels during the peeling process. Lactic acid peels are well-suited to patients with acne-prone skin that is also dry, dehydrated or sensitive — a combination that can make more aggressive acids less tolerable. They are often used as introductory peels for patients new to chemical exfoliation.
Combination and multi-acid peels
In some cases, your doctor may recommend a combination peel that blends two or more acids to target multiple acne mechanisms simultaneously. For example, a peel combining salicylic acid with mandelic acid can address both pore congestion and surface texture in a single session. Multi-acid formulations allow for a more comprehensive treatment while keeping individual acid concentrations at levels that minimise irritation.
TCA peels for deeper concerns
Trichloroacetic acid (TCA) peels are medium-depth peels that penetrate into the papillary dermis. They are not typically used as a first-line treatment for active acne but may be considered for patients with more stubborn post-acne scarring, deeper PIH or textural irregularities that have not responded adequately to superficial peels. TCA peels require more downtime and are performed at longer intervals. For significant scarring, your doctor may recommend Alma Hybrid CO2 laser resurfacing as a more targeted alternative.
Peel depth levels
Superficial peels affect only the outermost layer of the epidermis (stratum corneum and upper stratum granulosum). These include most salicylic, glycolic, mandelic and lactic acid peels used for acne. They involve minimal downtime — typically 1–3 days of mild flaking — and are safe for repeated use every 2–4 weeks.
Medium-depth peels penetrate through the full epidermis into the upper dermis. TCA peels and higher-concentration glycolic peels fall into this category. They produce more visible peeling over 5–7 days and are spaced 4–8 weeks apart. Medium-depth peels are typically reserved for more resistant concerns or used after a course of superficial peels.
Treatment pathways
Based on your clinical assessment, your doctor will recommend a treatment pathway that may include chemical peels as a standalone treatment or as part of a broader acne management protocol. Below are the core modalities we use alongside and in support of chemical peels for acne.
What to expect during a peel session
A chemical peel session at Berkshire Aesthetics typically takes approximately 30 minutes, including preparation and post-peel care. Understanding the process can help you feel confident and informed before your appointment.
Before your first peel, your doctor will assess your skin under clinical lighting, confirm your acne type and severity, review any current skincare or medications (including retinoids) and select the most appropriate peel for your skin. If you are a new patient, this takes place during your initial consultation.
Your skin is thoroughly cleansed to remove makeup, oil and surface debris. A degreasing solution may be applied to ensure the peel acid contacts the skin evenly and penetrates consistently.
The selected acid solution is applied to the treatment area using a brush or gauze pad. Your practitioner monitors the skin’s response closely throughout, noting any changes in colour or frosting that indicate the depth of penetration.
You will likely feel a tingling or mild warming sensation as the acid works. Some patients describe a slight stinging, which is normal and subsides quickly. If discomfort is significant, the peel can be neutralised early. Salicylic acid peels tend to produce less stinging than glycolic acid peels.
After the appropriate contact time (typically 2–10 minutes depending on the acid and concentration), the peel is neutralised with a bicarbonate solution or rinsed with water. Some peels, such as salicylic acid, are self-neutralising and do not require a separate neutralisation step.
A soothing moisturiser and broad-spectrum SPF are applied immediately after the peel. Your practitioner will provide detailed written aftercare instructions and discuss what to expect in the days following treatment.
Expected results and timeline
Chemical peels for acne produce cumulative results. While some patients notice visible improvement after their first session, the most significant benefits develop progressively over a course of treatments.
You may notice smoother skin texture, reduced oiliness and a brighter complexion once any initial flaking subsides (typically within 2–3 days for superficial peels). Some patients experience a mild “purge” where congestion is brought to the surface before clearing, which is a normal part of the process.
Progressive improvement in acne severity, pore congestion, post-acne marks and overall skin clarity. Each peel builds on the previous session, with your doctor adjusting the acid type or concentration as your skin responds. Most patients see their best results by the end of a full course, typically spaced 2–4 weeks apart.
Once your acne is under control, monthly maintenance peels can help sustain results, prevent recurrence and keep pores clear. Maintenance sessions are often lighter than the initial treatment course and may be combined with other modalities such as HydraFacial or LED therapy for enhanced outcomes.
Risks and safety
Chemical peels are well-established treatments with strong safety profiles when performed by qualified practitioners. However, all treatments carry some degree of risk, and we ensure you are fully informed before proceeding.
- Temporary redness, mild flaking or visible peeling is expected and typically resolves within 1–5 days depending on peel depth
- Increased skin sensitivity to touch, products and environmental factors for several days following treatment
- Heightened photosensitivity requiring diligent sun protection — UV exposure on freshly peeled skin can cause pigmentation changes
- Chemical peels are not suitable during pregnancy or breastfeeding due to systemic absorption concerns
- Patients using retinoids (tretinoin, adapalene or isotretinoin) may need to pause use before and after peels to avoid excessive irritation
- Patch testing may be recommended for patients with very sensitive or reactive skin before a full-face peel is performed
- Rare risk of post-inflammatory hyperpigmentation, particularly in darker skin tones if inappropriate peel selection or aftercare non-compliance occurs
All contraindications are assessed during your consultation. Your doctor will explain the specific risks relevant to your skin type and medical history, and will only proceed when it is clinically safe to do so.
Aftercare
Proper aftercare is essential for maximising the results of your chemical peel and protecting your skin during the healing process. Your practitioner will provide personalised, written aftercare instructions, but the following principles apply to most acne peels:
- Apply broad-spectrum SPF 30 or higher every morning without exception — this is the single most important aftercare step to prevent pigmentation and protect newly revealed skin
- Avoid active skincare ingredients (retinoids, vitamin C serums, AHAs, BHAs and benzoyl peroxide) for 48–72 hours after your peel to allow the skin barrier to recover
- Use a gentle, fragrance-free cleanser and a hydrating moisturiser recommended by your practitioner during the recovery period
- Do not pick, pull or manually remove peeling skin — allow it to shed naturally to avoid scarring, infection or uneven results
- Avoid excessive heat, saunas, steam rooms and vigorous exercise for 24–48 hours after treatment
- Follow your prescribed post-peel skincare regimen consistently between sessions to maintain the improvements achieved by each peel
If you experience prolonged redness, unexpected blistering or any unusual reaction, contact the clinic promptly. Our team is available to advise and will schedule an early review appointment if needed.
Combining peels with other treatments
Chemical peels are highly effective as a standalone acne treatment, but they can also be combined with complementary modalities for enhanced results. Your doctor will advise on the optimal sequencing and timing of combination treatments based on your individual plan.
HydraFacial before peels
A HydraFacial performed before a chemical peel session can improve peel efficacy by deeply cleansing the skin, extracting comedones and removing surface debris. This allows the peel acid to contact the skin more evenly and penetrate more effectively. HydraFacial is particularly useful for patients with heavily congested skin who would benefit from mechanical extraction before chemical exfoliation.
LED therapy post-peel
Dermalux LED therapy is an excellent complement to chemical peels. Blue light (415nm) provides additional antibacterial activity against C. acnes, while red light (633nm) and near-infrared light (830nm) reduce post-peel inflammation, accelerate healing and support cellular repair. LED can be performed immediately after a superficial peel or at a separate session within the same week.
Medical skincare between sessions
Your prescribed medical-grade skincare regimen works synergistically with in-clinic peels. Products containing retinoids maintain accelerated cell turnover between sessions, niacinamide regulates oil production and salicylic acid cleansers keep pores clear. Your doctor adjusts your home regimen as your skin improves.
Addressing scarring after peels
Once active acne is brought under control through peels and supportive treatments, residual scarring can be addressed with collagen-remodelling technologies such as Alma Hybrid CO2 laser. Peels alone can improve mild post-acne marks and PIH, but deeper ice pick, boxcar or rolling scars typically require laser or microneedling for significant structural improvement. See our acne scar treatment page for more information.
