What is a chemical peel?

Chemical peels are cosmetic treatments that have gained popularity in recent years. They offer a non-surgical solution to various skin concerns, including acne, aging signs, hyperpigmentation, and uneven texture. This article aims to provide a comprehensive understanding of chemical peels, including their types, process, benefits, risks, aftercare, and expected results.

What is a chemical peel?


A chemical peel is a dermatological procedure that involves the application of a chemical solution to the skin. This solution exfoliates the top layers of the skin, promoting cell turnover and revealing a rejuvenated, healthier skin layer underneath. Chemical peels vary in intensity, from superficial peels targeting the outermost layer to deep peels that penetrate multiple skin layers.


  1. Superficial Peels: These mild peels primarily exfoliate the outermost layer of the skin, the epidermis. They are often made of alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), such as glycolic acid or salicylic acid, respectively. Superficial peels are suitable for treating minor skin concerns and require minimal downtime.
  2. Medium Peels: These peels reach deeper into the skin, targeting the epidermis and upper dermis. They typically contain trichloroacetic acid (TCA) and can address moderate skin imperfections like wrinkles, sunspots, and acne scars. Medium peels may require a longer recovery period.
  3. Deep Peels: Deep peels penetrate several layers of the skin, reaching the mid-dermis. They often involve phenol as the active ingredient and are suitable for severe skin concerns. Deep peels provide significant results but necessitate a more extended recovery time.


The process of a chemical peel involves several steps:

  1. Consultation: A dermatologist assesses the patient’s skin condition, discusses expectations, and recommends the appropriate peel type.
  2. Preparation: Before the peel, the skin is thoroughly cleansed and prepped. In some cases, a pre-peel skincare regimen may be advised to optimize results.
  3. Application: The chemical solution is applied to the skin using a brush or a cotton swab. The dermatologist ensures an even and controlled application.
  4. Duration: The peel’s duration depends on the peel type and desired results. It can range from a few minutes for superficial peels to over an hour for deep peels.
  5. Neutralization: Once the desired time is reached, the peel is neutralized to stop the chemical reaction on the skin.


Chemical peels offer numerous benefits for the skin:

  1. Skin Rejuvenation: Chemical peels promote the growth of new skin cells, resulting in a fresher and more youthful complexion.
  2. Acne Treatment: Peels can effectively address acne by unclogging pores, reducing inflammation, and controlling sebum production.
  3. Hyperpigmentation Reduction: Chemical peels can lighten dark spots caused by sun damage, melasma, or post-inflammatory hyperpigmentation.
  4. Wrinkle Reduction: Medium and deep peels stimulate collagen production, reducing the appearance of fine lines and wrinkles.
  5. Improved Texture: Peels smooth out rough skin texture, refining pores and reducing the visibility of scars.


While chemical peels are generally safe, they do carry some risks and potential side effects:

  1. Skin Irritation: Peels can cause temporary redness, stinging, or burning sensations, which usually subside within a few hours or days.
  2. Hyperpigmentation: In rare cases, the skin may darken or develop patches of hyperpigmentation after a peel. This risk is higher for individuals with darker skin tones.
  3. Infection: Improper aftercare or unsterile conditions during the procedure can lead to infection. It is crucial to follow the dermatologist’s instructions for post-peel care.
  4. Scarring: Deep peels carry a higher risk of scarring, especially if not performed by an experienced professional.


Proper aftercare is essential to maximize the benefits and minimize complications after a chemical peel:

  1. Sun Protection: Avoid sun exposure and apply sunscreen diligently to protect the new skin from damage.
  2. Moisturize: Keep the skin hydrated with a gentle, non-irritating moisturizer.
  3. Avoid Scrubbing: Refrain from scrubbing or exfoliating the treated area until it has fully healed.
  4. Follow Instructions: Adhere to the dermatologist’s post-peel instructions regarding skincare products, makeup, and activities to avoid.


The results of a chemical peel vary depending on the peel type and individual factors. Generally, the skin gradually improves over several weeks following the peel, with maximum benefits visible after multiple sessions. Deeper peels provide more significant results but require a longer recovery period.

Suitable Candidates

Chemical peels are suitable for many individuals seeking skin rejuvenation or treatment for specific concerns. However, it is important to consult with a dermatologist to determine if a chemical peel is appropriate for one’s skin type and condition. Individuals with active infections, eczema, or hypersensitivity to peel ingredients may not be suitable candidates.


Chemical peels offer a versatile solution for various skin concerns, promoting a more youthful and rejuvenated complexion. With different peel types available, individuals can find the right option for their specific needs. However, it is crucial to consult with a dermatologist to determine the suitability of a chemical peel and ensure proper aftercare to achieve the best possible results.
