What side effects can occur after a chemical peel?

Chemical peels, although they bring many benefits, are also associated with the possibility of various side effects. Their type and intensity depend on the depth of the procedure, the preparations used, individual skin predispositions, and proper post-treatment care. Below is a detailed overview of the potential side effects:

1. Transient Side Effects

Redness and Swelling:
Immediately after the procedure, the skin may appear red, and in the case of medium-depth or deep peels, a slight swelling may occur. These symptoms usually subside within a few hours to several days.
Sensation of Burning and Tingling:
A mild burning or tingling sensation is typical, especially when using stronger acids. This sensation is usually short-lived, although it can be more intense with deep peels.
Peeling and Exfoliation:
During the regeneration process, there is an intense exfoliation of dead skin cells, which may be accompanied by visible peeling, a feeling of tightness, and dryness.

2. Side Effects Related to Pigmentation Changes

Post-Treatment Hyperpigmentation:
Especially in individuals with darker skin tones, the procedure can temporarily cause localized hyperpigmentation. These usually resolve over time, but in some cases, they may become permanent if the skin is not properly protected from the sun.
Hypopigmentation:
In rare cases, particularly after deep peels, lighter areas may appear on the skin due to excessive loss of pigment.

3. Risk of Infections and Scarring

Infections:
If proper hygiene standards are not maintained during the procedure or post-treatment care, there is a risk of secondary bacterial, viral (e.g., reactivation of herpes simplex virus), or fungal infections.
Scarring:
In cases where the skin tends to form scars (e.g., keloids) or when the procedure is performed too deeply, hypertrophic scars may develop. That is why an individual patient evaluation and appropriate selection of the peel depth are so important.

4. Other Potential Side Effects

Increased Sun Sensitivity:
After a peel, the skin becomes more sensitive to UV rays, which can result in sunburn and worsening of hyperpigmentation. Therefore, the use of sunscreens with a high SPF is essential.
Irritation and Dryness:
The procedure can lead to a sensation of dryness, tightness, and temporary discomfort. Intensive moisturizing and regenerating care can help alleviate these symptoms.
Allergic Reactions:
Although rare, some individuals may experience allergic reactions to the ingredients in the chemical peel preparations, which can manifest as redness, itching, or swelling.

Factors Influencing the Occurrence of Side Effects

Depth of the Peel:
The deeper the peel, the greater the risk of side effects. Superficial peels are generally safer and cause fewer complications, while deep peels require a longer recovery time and careful care.
Skin Type:
Sensitive skin, skin prone to irritation, or a history of dermatological issues (e.g., acne, eczema) is more susceptible to side effects.
Post-Treatment Care:
Improper or insufficient post-treatment care can increase the risk of complications such as infections or pigmentation changes.

After a chemical peel, both transient side effects—such as redness, swelling, burning, peeling, and dryness—and potentially more long-lasting issues, such as pigmentation changes, scarring, or increased sun sensitivity, may occur. It is crucial to have an individual patient evaluation, choose the appropriate method of peel, and follow post-treatment care recommendations to minimize the risk of complications and achieve optimal results.
