Chemical Peels: Effects, Types, and Application for More Radiant Skin
A chemical peel uses specific acids to dissolve dead skin cells and actively stimulate natural cell renewal. Depending on the type of acid, the treatment can be precisely tailored to different skin needs.
TABLE OF CONTENTS
What is a chemical peel?
A chemical peel is a skin treatment in which special acids dissolve dead skin cells and stimulate cell renewal – according to the American Academy of Dermatology, they are among the most effective methods of chemical exfoliation. In contrast to mechanical peels with abrasive particles, they work more evenly and are generally gentler on the skin tissue.
The three most important types of acids at a glance:
- AHA (Alpha-Hydroxy-Acids): e.g., Glycolic acid or Lactic acid – work on the skin surface and can improve radiance and moisture content.
- BHA (Beta-Hydroxy-Acids): primarily Salicylic acid – oil-soluble, penetrates pores and can help with acne and blackheads.
- PHA (Poly-Hydroxy-Acids): e.g., Gluconolactone – the gentlest variant, antioxidant and hydrating, suitable for sensitive skin.
Effects and benefits
The acids weaken the bonds between dead skin cells and allow for their controlled shedding, as described by DermNet NZ. At the same time, skin renewal is stimulated, bringing fresher, more even skin to the surface. Depending on the acid used, the peel works superficially or somewhat deeper into the skin layers.
Chemical peels specifically break the bonds between dead skin cells – paving the way for fresh, more even skin.
Regular use can contribute to:
- Smoother skin surface and refined complexion
- Radiant, more even complexion
- Fewer keratinizations and blackheads
- Improved absorption capacity for subsequent skincare products
- Support for hyperpigmentation and dull skin
Application and tolerability
For home use, low concentrations and a cautious start with one application per week are recommended. The frequency can be gradually increased, provided the skin tolerates it. Professional peels in dermatology or cosmetic studios use higher concentrations and are suitable for pronounced hyperpigmentation or scars.
After a chemical peel, the skin is more sensitive to UV light. Daily sun protection is essential. In case of redness or irritation, the frequency of application should be reduced and the concentration adjusted.
Combination with other active ingredients
- Hyaluronic Acid & Ceramides: important after a peel for rehydration and strengthening the skin barrier.
- Niacinamide: calms the skin, can reduce redness, and helps strengthen the barrier function.
- Retinol: should not be used simultaneously with a strong peel – alternating use on different evenings is recommended.
Suitable for which skin type?
- Blemish-prone skin: BHA works in clogged pores and can help with blackheads and acne.
- Dull or dry skin: AHA promotes radiance and can improve moisture content.
- Sensitive skin: PHA offers gentle exfoliation with lower irritation potential.
- Anti-aging: AHAs and combination peels are often used to help with fine lines and uneven texture.
- Hyperpigmentation: Regular use can visibly lighten pigment spots.
Frequently asked questions about chemical peels
How often should one use a chemical peel?
For home use, once or twice a week is sufficient. Those new to chemical peels should start with once a week and gradually increase the frequency if the skin tolerates it.
Can a chemical peel be combined with Retinol?
Not simultaneously. Both active ingredients are potent exfoliants – combined, they can lead to irritation. Alternating use is recommended, for example, peeling on certain evenings, Retinol on others.
Which chemical peel is suitable for sensitive skin?
PHA acids like Gluconolactone are the gentlest choice. They exfoliate gently, simultaneously strengthen the skin barrier, and cause significantly less irritation than AHA or BHA.
Conclusion
Chemical peeling is one of the most effective methods for a refined complexion, even skin tone, and improved skin structure. With the right acid, concentration, and frequency of application, chemical exfoliation can be safely integrated into any skincare routine – combined with soothing and hydrating active ingredients for optimal tolerability.
