Beta hydroxy acid (BHA) peels are powerful chemical peels known for their ability to penetrate deep into the skin. Unlike alpha hydroxy acids (AHA), BHA peels are oil-soluble, making them particularly effective for individuals with oily skin and acne-prone skin.
These peels remove dead skin cells, unclog pores and reduce inflammation. Whether you’re dealing with acne scars or uneven skin texture or simply looking for a deep cleanse, BHA peels are a good option for various skin types.
What Are Beta Hydroxy Acid (BHA) Peels?
BHA peels are chemical peels that primarily use salicylic acid. This chemical breaks down the bonds between dead skin cells, promoting faster cell turnover and cleansing the pores. Because BHA peels are oil-soluble, they can penetrate sebaceous (oil) glands, making them highly effective for treating acne-prone skin and reducing excess oil production.
Why Choose BHA Peels?
- Penetrate deep into pores for a thorough cleanse.
- Ideal for oily skin and acne-prone skin.
- Help reduce the visibility of acne scars and cleanse clogged pores.
- Reduce inflammation and promote an even skin texture.
Key Ingredient & Composition
Salicylic Acid. This chemical is known for removing dead skin cells, unclogging pores and reducing inflammation. Its pH level is typically between 3.0 – 4.0, making it optimal for deep skin penetration.
How Do BHA Peels Work?
Once applied, beta hydroxy acid breaks down the bonds that hold dead skin cells together. It also dissolves excessive oils to ensure your pores are free from impurities.
Additional Acids Sometimes Included
- Mandelic Acid – A milder exfoliant, often used for sensitive skin.
- Citric Acid – Helps brighten and even out skin texture.
- Tartaric Acid – Works alongside AHA BHA combinations for enhanced exfoliation.
- Poly Hydroxy Acids – A gentler alternative for dry skin types.
Benefits of Beta Hydroxy Acid (BHA) Peels
BHA peels offer multiple benefits, making them a preferred choice for enhancing skin clarity, texture and health.
1. Exfoliation and skin renewal
BHAs ability to remove dead skin cells helps encourage skin regeneration.
2. Oil and acne control
BHA peel dissolves oil, preventing breakouts and unclogging pores. It also reduces blackheads and whiteheads, and helps with acne-prone skin by slowing down sebum production. Last but not least, it helps reduce inflammation and calms irritation caused by acne.
3. Skin tone and hyperpigmentation
Beta hydroxy acids can help reduce post-acne marks and address sun damage and uneven skin tone. They also help you gain a brighter complexion through consistent exfoliation.
4. Long-term skin health
BHA helps stimulate collagen production, reducing fine lines and wrinkles. It also helps tighten enlarged pores and combat the damaging effects of frequent sun exposure.
Who Should Use BHA Peels?
BHA peels are ideal for individuals looking to address oily and acne-prone skin and clogged pores. They are particularly beneficial for those dealing with blackheads and whiteheads, as well as individuals aiming to improve skin tone and texture.
Skin Types Best Suited for BHA Peels
| Skin Type | Benefits of BHA Peels |
|---|---|
| Oily Skin | Controls excess oil, unclogs pores |
| Acne-Prone Skin | Reduces breakouts, minimises inflammation |
| Combination Skin | Balances oil and hydration levels |
| Normal Skin | Enhances glow, improves texture |
When to Avoid BHA Peels
BHA peels are not recommended for everyone. Consider avoiding them if:
- You have extremely dry or compromised skin, as it may increase the risk of irritation.
- You’re using strong retinoids or other exfoliants. This is to prevent the risk of over-exfoliation.
- You have allergies to salicylates (common in aspirin-sensitive individuals).
How to Use a BHA Peel Safely
Using a BHA peel correctly ensures you will reap its benefits while minimising the chances of developing irritation. Proper application, frequency and post-care are essential when using this peel.
Step-by-Step Application Guide
- Preparation: Cleanse your skin with warm water and pat dry. Make sure your skin is completely dry before applying.
- Application: Apply a thin layer of the product evenly over your skin.
- Waiting Time: Leave on for the recommended duration (varies based on higher concentrations used).
- Rinse Off: Use lukewarm water to rinse the peel thoroughly.
- Post-Care: Apply a hydrating serum such as hyaluronic acid, and always wear sun protection to prevent damage from sun exposure.
Frequency of Use
- Over-the-counter, low-concentration peels are suitable for daily or every other day use.
- Moderate peels can be applied once a week.
- Planning to use professional-grade BHA peels? These are used in aesthetic clinics only, so it’s best to consult your practitioner first.
Following the proper routine and recommended frequency of use ensures safe results, whether you’re using them for acne treatment or wrinkle reduction.
BHA Peels vs. AHA Peels: What’s the Difference?
BHA and AHA peels serve different purposes in skincare, each addressing specific skin concerns. Below is a comparison of the two:
| Feature | BHA Peels (Beta Hydroxy) | AHA Peels (Alpha Hydroxy) |
|---|---|---|
| Solubility | Oil-soluble | Water-soluble |
| Exfoliation Depth | Penetrates pores and stratum corneum | Works on the top layer of the skin |
| Best for | Oily, acne-prone skin, keratosis pilaris | Dry, sun-damaged skin, age spots |
| Common Acids | Salicylic Acid | Glycolic, lactic, mandelic acids |
| Benefits | Unclogs pores, reduces acne, balances oil production | Brightens skin, smooths fine lines, fades sun damage |
| Potential Irritation | More likely to cause irritation as it penetrates deeper into the skin | Can be irritating for sensitive skin |
Potential Side Effects and Precautions
While BHA peels offer multiple benefits, they can cause some skin reactions. Potential side effects include:
- Redness and irritation, especially when using higher concentrations.
- Dryness and flaking as it exfoliates the top layer of the skin.
- Increased sun sensitivity.
How to Minimise Irritation
- Always do a patch test on the inside of your arm before applying a peel to check for adverse reactions.
- Avoid using other exfoliants (e.g., retinoids) if you’re using BHA peels.
- Apply moisturiser day and night to keep the skin hydrated.
- Wear protective clothing and apply sunscreen to prevent sun damage.
Professional vs. At-Home BHA Peels
BHA peels are available in over-the-counter (OTC) products and aesthetic practitioner-administered treatments. But which is better? Find out below:
| Type of Peel | OTC (At-Home) BHA Peels | Professional BHA Peels |
|---|---|---|
| Concentration | Lower concentrations; gentler formulas | Higher concentrations; tailored to skin type |
| Best for | Routine exfoliation, mild acne | Treating deep acne, hyperpigmentation, enlarged pores |
| Recovery Time | Minimal, can be used regularly | Can cause peeling for several days |
| Application | Self-applied | Performed by an aesthetic practitioner |

Conclusion
BHA peels are an excellent option for those struggling with oily skin, acne, and clogged pores. Their ability to exfoliate dead skin cells, reduce breakouts and refine pores makes them popular for both at-home and professional treatments. Regular use can improve uneven skin texture, fade acne scars and promote a more radiant complexion.
However, post-peel care is essential. Always stay hydrated and wear adequate sun protection. Avoid over-exfoliation to maximise results and prevent sun damage. If you consider a professional-grade peel, consult a skincare professional for personalised recommendations.
