Chemical Peels

​

1. What Are Chemical Peels?

Chemical peels are a dermatological treatment in which a chemical solution is applied to the skin to exfoliate the outer layers. This process encourages the skin to shed its dead or damaged cells, promoting the growth of new, healthier skin underneath. Chemical peels are used to address various skin issues, including acne, aging, pigmentation issues, and uneven texture.

The strength and depth of a chemical peel can vary depending on the specific type used, which can be classified into superficial, medium, and deep peels.

2. How Do Chemical Peels Work?

Chemical peels work by applying a solution to the skin that causes the top layers of the skin to exfoliate and eventually peel off. This peeling process stimulates collagen production and allows fresh, smooth skin to emerge. There are three main types of chemical peels:

• Superficial Peels: These are the mildest types of chemical peels and affect only the outermost layer of skin (epidermis). They are used to treat minor skin imperfections such as dry, dull skin, and mild acne.

• Medium Peels: These penetrate deeper into the skin, reaching the middle layers (dermis). Medium peels are used to treat more pronounced skin issues, such as moderate wrinkles, pigmentation problems, and acne scarring.

• Deep Peels: These are the most intense type of chemical peel and can penetrate deeper into the dermis. They are used to treat severe skin issues like deep wrinkles, scars, and hyperpigmentation.

3. Types of Chemical Peels

Chemical peels come in various formulations, each designed to treat specific skin concerns. The most common types include:

• Alpha Hydroxy Acids (AHAs): These are mild acids, such as glycolic or lactic acid, that work on the surface layer of the skin. AHAs are often used for superficial peels, addressing dry skin, minor discoloration, and fine lines.

• Beta Hydroxy Acid (BHAs): Salicylic acid is the most common BHA, which penetrates deeper into the pores to treat acne and oily skin. It helps to exfoliate and clear clogged pores, making it ideal for acne-prone skin.

• Trichloroacetic Acid (TCA): This acid is used in medium-depth peels and is effective for treating moderate to severe skin concerns, including pigmentation issues, scarring, and fine lines.

• Phenol: Used in deep peels, phenol is one of the strongest acids available for chemical peels. It is typically used to treat deep wrinkles, severe sun damage, and advanced skin aging.

4. Cosmetic Uses of Chemical Peels

Chemical peels are primarily used to treat cosmetic concerns related to the skin, including:

• Acne and Acne Scarring: Chemical peels can help clear acne by exfoliating the skin, reducing excess oil, and preventing clogged pores. They also help to fade acne scars and reduce hyperpigmentation.

• Fine Lines and Wrinkles: By stimulating collagen production, chemical peels can reduce the appearance of fine lines and wrinkles, especially around the eyes and mouth.

• Hyperpigmentation: Chemical peels are effective in reducing pigmentation problems, such as age spots, sun damage, and melasma, by removing the upper layers of skin that contain excess pigment.

• Uneven Skin Tone and Texture: Regular use of chemical peels can help improve overall skin texture, smooth rough patches, and promote a more even skin tone.

• Sun Damage: Chemical peels can address issues caused by prolonged sun exposure, such as dark spots, wrinkles, and rough skin texture.

5. Medical Uses of Chemical Peels

In addition to cosmetic applications, chemical peels can be used for certain medical treatments:

• Precancerous Growths: In some cases, chemical peels can help remove precancerous skin cells, such as actinic keratosis.

• Scar Reduction: Chemical peels can be used to treat certain types of scarring, such as those caused by burns or surgical wounds.

• Psoriasis and Keratosis: Chemical peels can sometimes help treat specific skin conditions like psoriasis and seborrheic keratosis by reducing inflammation and encouraging new skin growth.

6. Procedure and Treatment Process

• Consultation: The process begins with a consultation to assess the client's skin type, concerns, and medical history. The practitioner will determine which type of chemical peel is best suited to the client’s skin and goals.

• Application: During the treatment, a chemical solution is applied to the skin, which may cause a mild tingling or stinging sensation. Depending on the type of peel, the solution is left on the skin for a few minutes before being neutralized or removed.

• Duration: A chemical peel session typically takes 30 minutes to an hour, depending on the type and area being treated.

• Discomfort: For superficial peels, clients may feel a mild tingling or stinging, but deeper peels may cause more discomfort, such as a burning sensation or intense itching. Local numbing may be used for medium and deep peels.

• Downtime: Superficial peels have minimal downtime, while medium and deep peels require longer recovery periods. Redness, peeling, and irritation are common in the days following the procedure.

7. Results

• Onset: Clients typically notice immediate improvements in skin texture, smoothness, and brightness after superficial peels. For medium and deep peels, full results may take several weeks to appear as the skin heals.

• Duration: Results vary depending on the type of chemical peel. Superficial peels may require frequent treatments (every 4-6 weeks), while medium and deep peels provide longer-lasting results but require fewer sessions.

• Maintenance: To maintain the results, clients may need to undergo periodic chemical peels, or complement the treatment with at-home skincare products (such as retinoids or sunscreens).

8. Safety and Side Effects

Chemical peels are generally safe when performed by a licensed professional. However, potential side effects include:

• Redness: Especially common after deeper peels, redness can last anywhere from a few hours to a few days.

• Swelling and Irritation: Some swelling and irritation may occur, particularly after medium and deep peels.

• Dryness and Flaking: Peeling and dryness are common side effects as the skin heals, and may last for several days after treatment.

• Hyperpigmentation or Hypopigmentation: In rare cases, chemical peels can cause changes in skin pigmentation, either darkening (hyperpigmentation) or lightening (hypopigmentation).

• Scarring: There is a slight risk of scarring with deep peels, especially if the skin is not properly cared for during the healing process.

• Infection: Although rare, infections can occur, particularly if the treated area is not properly protected during the healing period.

9. Who Should Not Use Chemical Peels?

Chemical peels may not be suitable for everyone, particularly individuals with:

• Active skin infections such as herpes or eczema in the treatment area

• Pregnant or breastfeeding women (especially with certain chemicals like salicylic acid)

• Dark skin types: People with darker skin tones may be at higher risk of hyperpigmentation or hypopigmentation, especially after deep peels.

• Severe acne or rosacea: Clients with active cystic acne or rosacea may need to avoid more intense peels unless advised by a professional.

• Recent sunburns or any type of skin irritation or injury in the treated area.

10. Aftercare Instructions

Proper aftercare is crucial to achieving the best results from a chemical peel and minimizing side effects:

• Avoid direct sun exposure: Sun exposure can increase the risk of pigmentation changes and irritation. Use a high-SPF sunscreen (30 or higher) daily, even indoors.

• Avoid hot showers and saunas: Heat can irritate the skin during the healing process.

• Moisturize regularly: Keep the skin hydrated with gentle, non-irritating moisturizers.

• Do not pick at peeling skin: Allow the skin to naturally exfoliate and shed to prevent scarring and irritation.

• Avoid makeup: For at least 24-48 hours post-peel, avoid applying makeup to minimize irritation and allow the skin to heal.

11. Cost

The cost of chemical peels can vary depending on the type of peel, the practitioner's expertise, and the area being treated. On average:

• Superficial peels may cost between £150 to £300 per session.

• Medium peels can range from £400 to £800 per session.

• Deep peels typically cost between £1,000 to £2,000 per session, depending on the complexity and the practitioner’s experience.

12. Chemical Peel Myths and Facts

Myth: Chemical peels always cause severe peeling and discomfort. Fact: While some peels cause visible peeling and mild discomfort, not all chemical peels result in dramatic peeling. Superficial peels usually only cause mild flaking and redness.

Myth: Chemical peels are only for older people with wrinkles. Fact: Chemical peels can benefit people of all ages. They are commonly used to treat acne, pigmentation issues, and skin texture problems in younger clients as well.

Myth: Chemical peels are dangerous and cause long-term damage. Fact: When performed by a licensed and experienced professional, chemical peels are safe and effective. They can be tailored to suit the client’s skin type and needs.

13. Alternatives to Chemical Peels

For clients who may not be candidates for chemical peels, or those looking for alternatives, there are other skin treatments available:

• Microneedling: Involves using tiny needles to create micro-injuries in the skin to stimulate collagen production and improve texture and tone.

• Laser treatments (e.g., fractional CO2 lasers or IPL): These treatments improve skin texture, tone, and pigmentation.

• Retinoid creams: Topical retinoids help with skin cell turnover, improving texture, acne, and fine lines over time.

• Hydrafacials: Non-invasive facial treatments that exfoliate and hydrate the skin using a combination of suction and serums
