The ideal profile
Suited to moderate to severe acne (grade II,III) with active papules and pustules, oily skin with enlarged pores, post-acne pigmentation (PIH), and hormonal acne in adult women. Age profile: most clients are 20-35, but the protocol also works on more mature types if their skin tolerates it. We especially recommend it for clients with post-acne marks (PIH), because the 12% AHA peel works on current acne and residual pigmentation at once. Also a fit for "mask acne", flare from extended face-mask wear (medical staff, service sector). The ideal seasonal window for a course: October,February; we skip summer entirely, because SPF cannot fully compensate for post-peel UV sensitivity. Sharper than the standard Deep Cleansing Therapy, so we choose it for more complex cases. For severe cystic acne (grade IV) with deep lesions, needs a dermatology consult and possibly systemic therapy before we run a cosmetic procedure. For mild acne (grade I), the gentler protocol is enough. We especially recommend it for clients with post-acne marks (PIH), because the 12% AHA peel works on current acne and residual pigmentation at once. Age profile: most clients are 20-35, but the protocol also works on more mature types if their skin tolerates it.
When to postpone
We do not perform the therapy during pregnancy or breastfeeding (azelaic acid not recommended), severe cystic acne with active abscesses, active skin diseases (eczema, psoriasis), active rosacea, recent sunburn. Isotretinoin currently or stopped less than 6 months ago, no. Allergy to AHAs or azelaic acid, yes. After laser or deep peel, 14 days. After injectable botox or fillers, 14 days. Hormonal acne therapy (contraceptives, spironolactone) is fine, but inform the specialist, because it affects our hydration strategy. Darker skin (Fitzpatrick IV,VI), the risk of post-inflammatory hyperpigmentation is higher; we start at 8% AHA and monitor. Active cold sore, wait until healed. Pause home retinol and strong AHA products 5 days before the session so the barrier is not overloaded at the same time as the in-studio peel. If you have an upcoming trip with intense sun, postpone the first session, post-AHA UV sensitivity lasts 7-10 days and SPF does not fully compensate.
Expectations and plan
A single session gives visible reduction of inflammation and cleaner skin for 7-10 days. A course of 4-6 sessions every 14 days plus consistent home care delivers 40-60% reduction in acne and visible tone evening. Real improvement comes with a course. This therapy does not replace medical care for hormonal acne, those cases may need a dermatologist and possibly contraceptives. After the first session expect cleaner skin for 7-10 days; after the third, noticeably fewer new inflammations; after the full course, stably clearer skin with 40-60% less acne. Maintenance with diet (less dairy and sugar), stress management, and SPF50 is critical. After the course we often shift to a gentler maintenance routine, the Deep Cleansing Therapy every 4-6 weeks, because the barrier needs rest between intensive AHA cycles. Expectations during the course: the first 2 sessions are "clearing", the result becomes visible from the 3rd session onward. PIH marks (dark spots left from healed acne) fade more slowly, 8-12 weeks, but the 12% AHA peel speeds up the process. Read how it works in the cabin and the aftercare plan. All protocols: catalog.

Who gets the best results
From our practice, three client profiles get the strongest result from acne therapy with AHA 12%. First: a woman aged 32-40 with early aging signs and an active home routine, for her, the cumulative course effect is most visible because the skin already works with actives and takes professional signals better. Second: a 40-50 year-old who has not had professional therapies before but has healthy, well-maintained skin, for her the first session often delivers a surprisingly strong effect because there is no built-up resistance. Third: a client over 50 with specific concerns (loss of density, uneven tone, fine lines), for her we work in a long course and pair with other protocols; the accumulated improvement over 3-4 months is significant. Who does not get the strongest result: women who try a single session just to test without home follow-up, or clients with a very thin barrier from aggressive home actives, for those we first restore, then stimulate. If you recognise yourself in the first three profiles, your chances of a real result are very high. If you recognise yourself in the fourth, say so at the consultation and we will start with a gentler protocol that prepares the skin for sharper sessions later. For the full candidate profile see the who-it-is-for article.
Is it for you? Self-assessment
Before booking acne therapy with AHA 12%, run through this short list. If you answer yes to at least 3 of 5, your chances of a real result are high. First: do you have at least one of the concerns this therapy specifically addresses (see the Ideal Profile section)? Second: does your skin tolerate active ingredients at home (retinol, acids, vitamin C) without a significant reaction? Third: do you have a daily routine in place with cleansing, serum, cream, and SPF50? Without that last one, the therapy will lose part of its effect. Fourth: can you commit to a course of at least 4 sessions over 6-8 weeks? A single session gives an initial effect, but real change comes from accumulation. Fifth: are you ready to add or maintain home care with the recommended products for at least 4 weeks after each session? If the answer is yes to most, book. If yes to 1-2, book a consultation first; we will recommend a better start or discuss how to prep the skin for this therapy. If no to most, there is a more suitable protocol for you, and at the consultation we will find it together. For the in-cabin walkthrough see the procedure article.
Compared with alternative protocols
We often get asked how acne therapy with AHA 12% compares with our other therapies. Compared with deep cleansing therapy this therapy fits a specific skin profile and a specific goal better. The two therapies are not interchangeable, they work on different mechanisms and we often combine them in one course for a fuller effect. The choice depends on three factors: your goal (glow, rejuvenation, lifting, tone evening), your skin type (normal, dry, oily, sensitive), and your skin history (have you had professional therapies before, do you use actives at home). At the consultation we review these three factors and propose a specific plan, often a combination of 2-3 therapies in a course that work synergistically. We do not recommend a one-size-fits-all therapy, results are much better when the protocol is specifically chosen. If you have had professional sessions before and know how your skin reacts to actives, say so, it speeds up the choice and often lets us start with a sharper plan from the start. See our full protocols catalog for a detailed comparison between therapies.
