Are chemical peels effective for treating scars? Whether you’re dealing with acne-induced marks or seeking to improve skin texture, a chemical peel for scars offers a range of solutions. This article examines the types and effectiveness of peels suitable for various scars, giving you a clear roadmap for your skin’s rejuvenation.

A chemical peel treatment is a procedure that uses a chemical solution to remove the top layers of the skin, stimulating the growth of new, smoother skin underneath. These peels are particularly effective in reducing acne and acne scars, improving hyperpigmentation, and treating fine lines. They achieve this by stimulating collagen production and removing discolored, dead skin cells, enhancing the appearance of acne scarring and post-inflammatory hyperpigmentation.

There are different types of chemical peels – light, medium, and deep peels – each with varying penetration depths and tailored to treat specific kinds of acne scars. Deep chemical peels, for instance, incorporate special techniques like Chemical Reconstruction of Skin Scars (CROSS) to effectively reduce severe acne scars.

Chemical peels have shown to be effective in improving a variety of acne scars, including rolling, boxcar, and ice pick scars. Various peels, including glycolic acid, phenol, TCA, and Jessner’s peel, can be customized to address these specific scars.

The precision and effectiveness of CROSS make it an attractive option for individuals seeking to diminish these types of acne scars and regain smooth, clear skin.

While traditional chemical peels are effective for treating acne scars, CROSS is a specialized technique that offers more precision. The name “CROSS” stands for Chemical Reconstruction of Skin Scars, and it involves the application of a much stronger concentration of an acid directly into the scars.

This technique can be classified as a ‘deep’ chemical peel due to its use of potent chemicals like phenol. However, the high concentration of acid in CROSS provides a more targeted treatment, avoiding damage to the healthy skin surrounding the scars.

The selection of the appropriate chemical peel, a pivotal step in the treatment process, should consider factors such as skin type, skin tone, and specific skin concerns. For instance, if you have sensitive skin, superficial peels that provide gentle exfoliation and hydration, such as enzyme peels derived from fruits like papaya or lactic acid peels, are recommended.

On the other hand, for darker skin tones, glycolic acid peels can be used safely but with caution to minimize risks of transient post-inflammatory hyperpigmentation due to the increased melanocyte activity.

Chemical peels are classified into three depth levels: light, medium, and deep. Each level denotes the intensity of the treatment, which commences with skin cleansing and patient preparation for the chemical solution application. During the peel, solutions such as glycolic or salicylic acid for light peels, trichloroacetic acid with glycolic acid for medium peels, and carbolic acid for deep peels, are applied, causing immediate skin responses such as whitening and stinging.

After the treatment, peeling typically occurs from 7 to 10 days, starting around the areas of the nose and mouth. Side effects such as redness, tightness, and swelling can be managed by recommended treatments like hydrocortisone for inflammation. And remember, proper SPF protection is a must throughout the chemical peel process to prevent further sun damage to the newly exposed skin layers.

Successful chemical peeling hinges on proper preparation. You should avoid using retinoids and acids such as salicylic or glycolic acid prior to a peel to prevent skin sensitivity. Moreover, exfoliation should be avoided for at least one week before a peel to prevent damaging the skin.

On the day of the peel, make sure to:

• Ensure your skin is well-hydrated
• Avoid drying skincare products a few days before treatment
• Prime the skin with depigmenting agents before the peel to enhance its effectiveness and decrease the risk of post-inflammatory hyperpigmentation (PIH).

Chemical peels are not only potent for treating acne scars but also beneficial in managing cystic acne. They promote exfoliation and enable deeper penetration into the skin to tackle the root causes of this severe acne type. They can:

• Alleviate active acne breakouts
• Diminish the appearance of acne scars
• Promote skin cell turnover
• Improve skin texture

However, it’s important to note that a temporary increase in acne, known as a ‘purge’ period, may occur post-treatment but typically resolves swiftly, especially for those with acne prone skin. In some cases, acne recurrences can last up to several weeks. To effectively treat acne and acne scars, a series of peel sessions might be required, combined with tailored skincare products.

Pre-Treatment Consultation

During the pre-treatment consultation, a thorough assessment of the patient’s medical history, current medications, and skin type is conducted. Priming the skin with a protocol of sunscreen and hydroquinone-containing cream prior to the CROSS helps minimize the risk of post-inflammatory hyperpigmentation, especially in patients with darker skin.

Before undergoing CROSS, patients should be screened for any allergies and sensitivities to the chemical peel components to avoid adverse reactions. A formal evaluation with a dermatologist is crucial to analyze the scars, develop a tailored treatment plan, and obtain informed consent prior to starting the CROSS procedure.

During the Procedure

During the procedure, coagulation of epidermal and dermal proteins is monitored through a frosty appearance on each treated atrophic scar. This indicates the proper application and start of the healing response. To preserve normal tissue, a precision applicator is recommended to prevent the spread of acid to adjacent healthy skin.

The procedure is usually comfortable for patients, and most do not require anesthesia as the sensation is similar to a tiny sting. The CROSS treatment typically takes 30-60 minutes, which can vary depending on the number of scars being treated.

Once the chemical peel process is complete, proper aftercare is critical to maintain the results. Use a gentle cleanser and apply it with your fingertips when washing your face post-peel to avoid irritation. Also, moisturize your skin frequently with non-comedogenic products to support the healing process.

Additionally, protecting the new skin from sun exposure is crucial. Use broad-spectrum physical sunblocks and wear protective clothing during the recovery period.

Lastly, avoid using products containing retinoids, acne medications, and exfoliants for a minimum of 2 weeks after the peel to prevent skin irritation.

The number of chemical peel sessions required to see results varies based on the severity of the acne scars and the type of peel used. Generally, four to six sessions are necessary to treat acne scars effectively.

For best results in treating acne and acne scars, a series of 3 to 6 peels is recommended, with treatments typically spaced three to four weeks apart, tailored to the individual’s skin response.

Despite the promising results of chemical peels in scar treatment, awareness of the accompanying risks is essential. People with darker skin tones have a higher risk of experiencing skin discoloration and further scarring from chemical peels.

During the healing process, chemical peels can cause:

• Inflammation that may lead to hyperpigmentation, especially in individuals with darker skin
• Increased risks, especially with stronger and deeper peels
• Longer recovery time required

Apart from chemical peels, various alternative scar treatments are also available. Laser resurfacing treatments can explicitly target thick scar tissue, and can be effectively used to improve different types of scars including atrophic scars, hypertrophic, and keloid scars.

Another alternative is microneedling, which has been shown to be a positive treatment method for addressing icepick and rolling acne scars. And then there are injectable options like steroids or botulinum toxin that can aid in reducing inflammation and redness in hypertrophic and keloid scars.

Improvements in acne scars from CROSS, TCA CROSS, or phenol CROSS are typically seen within 2-9 months, with peak collagen stimulation and subsequent scar improvement usually observed about 6 to 9 months after each treatment session. Patients are typically followed up at intervals of two months after the last treatment to assess the long-term results and any delayed side effects.

It’s important to note that individual outcomes may vary and not all patients will experience progressive improvement.

When comparing chemical peels with other acne scar treatments, it’s worth noting that lasers are generally considered more reliable. Lasers target scars more precisely and have shorter recovery times than chemical peels.

Furthermore, microneedling has been identified as a more effective option than glycolic acid chemical peels for acne scar treatment. This shows that while chemical peels are valuable in their own right, other treatments may offer more targeted and efficient results in certain cases.

Considering the range of available treatments, consulting a dermatologist for a personalized scar treatment plan can be beneficial. Dermatologists bring specialized expertise in skin health and can provide individualized care tailored to your specific concerns and aesthetic objectives.

They can design treatment plans customized to the nuances of each individual’s acne scars, ensuring the most effective results with acne scars chemical peels. So, don’t hesitate to seek professional advice when considering chemical peels for acne scars.
