A fruit acid peel is a chemical peel based on alpha hydroxy acids (AHAs) – naturally occurring acids such as glycolic acid, mandelic acid, or lactic acid that remove the superficial layers of the skin in a controlled way and specifically stimulate cell renewal. In the process, the active ingredients loosen the bonds between dead skin cells, stimulate collagen production, and noticeably improve the absorption of the skincare products applied afterward.
At our Skinthetics Cosmetics institute in Düsseldorf-Oberkassel, we use the fruit acid peel with the treatment concept directed by Dr. Lucija Grittern, specialist in dermatology – a decisive difference from ordinary beauty salons, especially when it comes to chemical peels. Typical areas of application are blemish-prone skin, pigment spots, first fine lines, and a dull complexion. Important to know: lasting effects develop mainly as part of a course of peels with 4-6 sessions – a single fruit acid treatment remains limited in its depth of effect.
Fruit acid peels are based on alpha hydroxy acids – AHAs for short – naturally occurring compounds from fruit, milk, or sugar cane. The most important active ingredients at a glance: Glycolic acid has the smallest molecular size of all AHAs, penetrates the skin most deeply, and has a correspondingly intensive effect. Mandelic acid is gentler and particularly well tolerated by sensitive skin. Lactic acid also improves the skin's ability to retain moisture. Salicylic acid is a BHA (beta hydroxy acid) and one of the oil-soluble acids, and it is particularly effective for blemish-prone skin with enlarged pores. The principle of action of all AHA peels is similar: the acids loosen the bonds between dead skin cells, promote natural flaking, and stimulate cell renewal and collagen production. The result is smoother, more even, and more radiant skin. Important for context: as a chemical peel, the fruit acid peel differs fundamentally from Green Peel, which works on the basis of herbs and enzymes – both have their place, depending on skin type and concern.
A fruit acid peel is suitable for a wide range of skin concerns:
- Blemish-prone skin and blackheads:
Particularly effective with a salicylic acid component (BHA)
- Hyperpigmentation and sun spots:
Through targeted cell renewal
- Mild acne scars:
Visible improvement possible for superficial scars
- First fine lines:
Collagen production is stimulated
- Dull, tired complexion:
Fresh skin cells reach the surface faster
- Enlarged pores and pore refinement:
Through deep-acting cleansing
Some contraindications should be known in advance: active skin infections or herpes simplex, recent sunburn, pregnancy and breastfeeding (consultation recommended as a precaution), use of isotretinoin (a break from treatment is necessary), and known allergies to acids. For deeper acne scars or pronounced melasma, we recommend specialized forms of treatment – we will be happy to advise you individually.
For lasting, visible skin improvement, 4-6 sessions at intervals of 2-4 weeks are usually necessary. A single fruit acid treatment does have a superficially refreshing effect and refines the complexion, but the actual skin renewal only builds up over several sessions. The course is designed to start with a lower concentration and gradually increase the strength depending on your individual skin tolerance. After the initial course, we recommend maintenance therapy every 2-3 months.
An honest note: if you are looking for a one-time miracle treatment, you will not find it in a fruit acid peel. Success lies in consistency – and in the accompanying home care.
Between the peel sessions, a HydraFacial is an excellent complementary skincare treatment – it supports hydration and strengthens the skin barrier during the recovery phases. For targeted pigmentation treatment without a chemical peel, our No More Dark Spots Facial is also a mild and effective alternative.
Choosing the right acid depends heavily on skin type and individual concerns:
Robust skin type, visible lines, pigmentation disorders
→ Glycolic acid (highly effective, penetrates deeply)
Sensitive skin or first experience with chemical peels
→ Mandelic acid (gentle, also well suited for summer)
Dry or undernourished skin
→ Lactic acid (also has a moisturizing effect)
Blemish-prone, oily skin with blackheads
→ Salicylic acid / BHA (oil-soluble, penetrates deep into the pores)
Which acid and which concentration actually suit you is determined by the individual skin analysis. At our Skinthetics Cosmetics institute, our team of estheticians decides based on a well-founded assessment – not a standard peel for everyone, but a treatment concept tailored to your skin.
After a fruit acid peel, the skin is significantly more sensitive to light than usual: freshly renewed skin cells are particularly vulnerable to UV radiation. Without consistent UV protection, there is a risk of post-inflammatory hyperpigmentation – paradoxically, exactly the opposite of the desired result. The following points are important:
- Daily SPF 50 sun protection for at least 14 days after each treatment
- Reapply every 2 hours during outdoor activities
- Avoid tanning beds throughout the entire course of peels
- Ideally, use mineral sunscreens
At our institute, we will be happy to advise you on suitable sunscreens from the SkinCeuticals range – tailored to your skin type and your home care.
The treatment concept of our cosmetic institute is directed by our experienced medical specialist, Dr. Lucija Grittern – setting a standard that purely cosmetic salons cannot offer.
On your first visit to our institute at Cimbernstraße 27a in Düsseldorf-Oberkassel, everything begins with a thorough skin analysis by our team of estheticians. Together with you, we look at your current skin condition and talk about your concerns, your skin tolerance, any pre-existing conditions, and your current skincare routine. On this basis, we select the right acid and starting concentration – for an initial course, typically a gentle start that is increased individually at the follow-up appointments. We then explain the process, possible skin reactions, aftercare, and sun protection to you before your skin is cleansed and your makeup is removed.
The acid is applied evenly to the cleansed skin with a brush or small sponge. During the application time – between 3 and 10 minutes, depending on the acid and concentration – a slight burning, tingling, or feeling of warmth is normal and usually well tolerated. Our team of estheticians continuously monitors your skin's reaction and neutralizes the acid earlier if necessary. This is followed by neutralization, a soothing mask, and the finishing skincare with serum, eye care, day cream, and SPF 50 sun protection. The entire fruit acid treatment takes 30-45 minutes.
Slight redness may appear immediately afterward, which usually subsides within a few hours or within 1-2 days at the latest. Exercise, saunas, and intense sun exposure should be avoided for 24-48 hours, and you should avoid tanning beds throughout your entire course of peels. Daily SPF 50 sun protection is a must for at least 14 days – without it, there is a risk of post-inflammatory hyperpigmentation. For home care, we recommend gentle cleansing, moisturizing products and, if needed, barrier-strengthening products from the SkinCeuticals or QMS Medicosmetics range. You should avoid products such as retinol or vitamin C for 3-5 days. The next appointment in your course of peels follows in 2-4 weeks.

Realistically, a completed course of peels often shows the following improvements: smoother and more even skin, visibly refined pores, a fresher and more radiant complexion, reduced hyperpigmentation, and fewer blackheads and blemishes. Many clients will notice first effects after just the second or third session – the optimal result shows once the complete treatment series is finished.
Success depends significantly on home care alongside the treatments and on consistent sun protection. Your individual starting point and skin type also play a decisive role – results therefore vary from person to person.
At Skinthetics Cosmetics, a fruit acid peel is priced starting at €135 per treatment. For lasting results, we recommend a course of peels with 4-6 sessions at intervals of 2-4 weeks. We will be happy to discuss a detailed overview of the costs during your individual consultation.
A single treatment takes 30-45 minutes – including skin cleansing, applying the acid, leaving it on, neutralization, and finishing skincare. On your first visit, you should allow additional time for consultation and skin analysis.
A fruit acid peel is usually not painful, but you will feel it. During the application time, a slight burning, tingling, or feeling of warmth occurs – which most clients describe as well tolerated. Our team of estheticians continuously monitors your reaction and adjusts the application time individually.
The initial course typically includes 4-6 sessions at intervals of 2-4 weeks. After that, we recommend maintenance therapy every 2-3 months. More frequent treatments are not advisable – the skin needs phases of recovery and rebuilding.
The first visible skin improvements often appear after the second or third session. The optimal result of the course of peels becomes visible once all 4-6 treatments are complete – smoother skin and a more even complexion build up gradually.
In principle, yes – but with extra caution. Consistent SPF 50 sun protection is a must in any case, and intense sun exposure should be avoided. During particularly sunny periods, we recommend milder acids such as mandelic acid, which is well tolerated even in summer.
The fruit acid peel is a chemical peel with AHAs – it specifically targets pigmentation and texture. Green Peel is a natural herbal peel that is massaged in by hand, with a somewhat longer regeneration phase for Green Peel Classic.
Both methods have their place, depending on the skin concern and type.
For mild to moderately blemish-prone skin and blackheads, yes – salicylic acid as a BHA in particular dissolves oil and clears the pores. For moderate to severe acne, dermatological treatment at the Skinthetics practice next door is advisable.
SPF 50 sun protection for at least 14 days, gentle cleansing, and moisturizing care are essential. You should avoid products such as retinol and vitamin C for 3-5 days. We recommend products from the SkinCeuticals and QMS Medicosmetics ranges for optimal aftercare.
Slight redness, a feeling of tightness, or superficial flaking are normal, short-lived reactions. If sun protection is neglected, there is a risk of post-inflammatory hyperpigmentation. Serious reactions are rare when the treatment is performed professionally – our team of estheticians will guide you carefully through the entire process.
