A few years ago, the AHA 30% + BHA 2% Peeling Solution from The Ordinary by Deciem revolutionized the skincare industry. Its release brought concepts like acid peels and chemical exfoliation into the mainstream, making them accessible without a dermatologist's visit. While The Ordinary offers a wide range of skincare products, the Peeling Solution remains one of their most consistently popular offerings.

What The Ordinary Says About AHA 30% + BHA 2% Peeling Solution
The brand states that Alpha hydroxy acids (AHA) exfoliate the uppermost layer of skin, contributing to a brighter and more even complexion. Simultaneously, Beta hydroxy acids (BHA) assist in managing pore congestion. Together, these acids work to combat visible blemishes and enhance skin radiance. With continued use, the product also promises to improve skin texture and reduce the appearance of fine lines.
Key Ingredients and Usage Recommendations
The formulation of the AHA 30% + BHA 2% Peeling Solution includes several key ingredients:
- Salicylic acid
- Lactic acid
- Tartaric acid
- Citric acid
Additionally, it contains a studied Tasmanian Pepperberry derivative, which helps to mitigate irritation often associated with acid use. Vitamin B5 is included to support skin healing, and black carrot provides antioxidant properties. The product has a pH of approximately 3.6 and is formulated without alcohol, oil, silicone, nuts, and gluten. It is also certified vegan and cruelty-free.
Due to the very high concentration of free acids, this product is recommended only for experienced users of acid exfoliation whose skin is not sensitive. It is advised not to use the solution on sensitive, peeling, broken, or compromised skin. The application time should not exceed 10 minutes, and it is not recommended for use more than twice a week. As the product can increase sensitivity to the sun, leading to a higher risk of sunburn, it is crucial to use sunscreen, wear protective clothing, and limit sun exposure during and for a week after using this product.
Benefits of The Ordinary AHA BHA Peeling Solution
This potent product offers several significant benefits for the skin:
- Dual Exfoliation: The combined power of AHAs and BHAs provides a comprehensive exfoliation of the skin.
- Clears Congested Pores: It effectively addresses congestion and blockages beneath the skin's surface.
- Fights Blemishes: The solution helps to combat visible blemishes on the skin.
- Boosts Radiance: It enhances the overall radiance and luminosity of the complexion.
- Improves Skin Texture: The product refines and smooths the appearance of skin texture.
- Reduces Fine Lines: Continued use can lead to a reduction in the appearance of fine lines and wrinkles.

How to Use The Ordinary Peeling Solution
Proper application is key to achieving the best results and avoiding adverse reactions:
- Cleanse Your Face: Begin by thoroughly cleansing your face.
- Ensure Skin is Dry: Wait for your skin to dry completely. This product must not be applied to wet skin.
- Apply Evenly: Using your fingertips, apply the solution evenly over your face and neck.
- Avoid Eye Area: Steer clear of the delicate eye area and mucous membranes.
- Limit Application Time: Leave the solution on for a maximum of 10 minutes.
- Rinse Thoroughly: Rinse off with lukewarm water, ensuring no contact with the eyes or the eye area during rinsing.
Understanding AHAs and BHAs in Skincare
Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are fundamental chemical exfoliants used in skincare to remove dead skin cells from the skin's top layer. AHAs, being water-soluble, primarily work on the skin's surface by loosening the bonds between dead skin cells (corneocytes), facilitating their removal and revealing smoother, brighter skin. Common examples include glycolic acid, lactic acid, citric acid, and hydroxycaprylic acid.
BHAs, on the other hand, are oil-soluble, with salicylic acid being the most prominent. This lipophilic nature allows BHAs to penetrate the sebum layer and delve deeper into the pores, effectively cleaning them from the inside out. Products containing salicylic acid can help improve fine lines and wrinkles, the color and texture of sun-damaged skin, and are particularly beneficial for acne.
PHA acids, such as Gluconolactone or Lactobionic Acid, are considered gentler alternatives. Their larger molecules penetrate the skin more slowly and superficially, significantly reducing the risk of irritation while still providing gentle exfoliation, moisturizing, and antioxidant benefits.

Potential Risks and Precautions
While AHAs and BHAs offer significant benefits, they can also cause skin irritation, redness, and increased sensitivity to the sun, potentially leading to sunburn for up to a week after use. It is advisable to consult a dermatologist before incorporating over-the-counter products containing these acids into your routine. They can assess suitability, potential interactions with medications, and recommend appropriate concentrations.
Generally, products with AHA concentrations of 10% or less and BHA concentrations of 1% to 2% are considered less risky. To minimize risks, it is recommended to perform a patch test on a small area of skin before full application. Always follow product instructions precisely and avoid overuse.
Products with AHAs may help with fine lines and wrinkles, discolored skin, age spots, and enlarged pores. BHAs, especially salicylic acid, can improve fine lines, the texture of sun-damaged skin, and acne.
Important considerations include:
- Patch Testing: Always perform a patch test before widespread use.
- Start Slowly: Begin with less frequent application to allow your skin to adjust.
- Sun Protection: Daily use of a broad-spectrum sunscreen with SPF 30 or higher is mandatory.
- Avoid Mixing: Do not use acids in the same routine as retinol, other strong acids, or high concentrations of vitamin C, especially if your skin is sensitive.
- Listen to Your Skin: Discontinue use if irritation occurs and focus on repairing and moisturizing the skin.
- Pregnancy and Breastfeeding: High concentrations of salicylic acid and retinoids should be avoided.
When to Use Acids Safely
Acids are generally best incorporated into an evening skincare routine. Mandatory daily use of a high-factor sunscreen (SPF 30, preferably SPF 50) is crucial to protect against UV radiation, prevent discoloration, and combat photoaging.
Avoid using acids in the same routine (e.g., the same evening) with retinol, other strong acids, or high concentrations of vitamin C. Always observe your skin's reactions, as acids are not suitable for everyone. Over-exfoliation can damage the skin's hydrolipidic barrier, leading to dryness and hypersensitivity.
For oily and acne-prone skin, salicylic acid (BHA) is often recommended. A mild chemical exfoliant might be suitable for dry or sensitive skin, while stronger formulations can benefit thicker, oilier skin types. However, individuals with darker skin tones or a history of post-inflammatory hyperpigmentation should exercise caution with strong exfoliants, as they could potentially cause discolored spots.
Can You Combine Acids with Vitamin C?
Combining acids (AHAs/BHAs) and vitamin C can be complex. While some sources advise against using them in the same routine due to potential irritation or efficacy issues, others suggest it's possible if the skin can tolerate it. AHAs and BHAs can lower the skin's pH, potentially creating an optimal environment for L-ascorbic acid (a form of vitamin C) to be absorbed effectively. If layering, apply the product with the lower pH first (typically the acid), followed by vitamin C. However, it's essential to understand the pH levels of your products. If you are short on time or concerned about irritation, choosing products with similar pH levels or using them at different times of the day (e.g., vitamin C in the morning, acids at night) is a safer approach.

Packaging and Formula of The Ordinary AHA BHA Peeling Solution
The Ordinary AHA BHA Peeling Solution is housed in a sturdy, frosted glass bottle containing 30ml of product. It features a dropper that dispenses the liquid easily and has proven to be resistant to clogging even with prolonged use. Due to its glass construction and twist-up cap with an attached dropper, careful handling is required during travel, and storage in a shaded area is recommended.
The formula itself is liquid, with a striking dark red color that can resemble blood. Its low viscosity means it is quite runny, necessitating caution during dispensing to avoid over-application.
Final Thoughts on The Ordinary AHA BHA Peeling Solution
The Ordinary AHA 30% + BHA 2% Peeling Solution is a potent and effective treatment for individuals seeking smoother, brighter, and clearer skin. It addresses multiple concerns, including acne, uneven texture, and signs of aging. With consistent and careful use, users can expect improvements in skin tone, a reduction in pore appearance, and a more radiant, youthful complexion. However, its high concentration means it is not suitable for everyone, particularly those with sensitive skin, rosacea, or active eczema. Consulting a dermatologist before use is highly recommended for these individuals.
