In any professional beauty salon, client safety is the number one priority. A patch test, also called derma testing, is a simple but vital step that helps identify how a client’s skin reacts to a product before a full treatment. It is commonly used for waxing, tinting, chemical peels, and lash lifts, or any service where a product is applied to the skin and could cause irritation.
The process is straightforward: a small amount of product is applied to a discreet area of skin, such as the inner arm or behind the ear, and left for 24 to 48 hours. During this time, the client observes the area for redness, swelling, itching, or other reactions. This controlled test allows estheticians to detect sensitivities early, reducing the risk of an allergic reaction during the actual treatment.
Patch testing is more than just a safety precaution; it shows clients that the salon cares about their wellbeing. Even professional-grade products, like Black Coral Wax, can cause reactions in sensitive individuals.

Why patch testing is essential for waxing services
Patch testing is especially important for waxing services because it can detect allergies to ingredients in the wax or aftercare products. Some clients may have sensitivities to natural wax ingredients or soothing oils that otherwise seem safe. A patch test not only prevents reactions but also demonstrates professionalism. Clients feel reassured when they see that the salon takes precautions to protect their skin.
In the UK, patch testing is often required by industry standards and insurance policies. Estheticians who skip this step may save time, but they increase the risk of complaints, skin irritation, or more serious allergic reactions. By performing a patch test, salons reduce liability and reinforce client confidence. It also provides an opportunity to educate clients about their skin type and sensitivities, which strengthens the relationship between client and salon.
Patch testing is particularly helpful for new clients or when introducing new products. It can prevent uncomfortable experiences and make clients feel valued, respected, and safe - turning a simple safety measure into a meaningful part of the salon experience.
How to perform a patch test correctly
Performing a patch test is simple but requires attention to detail. Start by choosing the product to test - this could be the specific wax intended for treatment, such as Black Coral Hard Wax or Plumeria Hard Wax, or a post-wax soothing oil. Apply a small amount to a clean, discreet area of skin, such as the inner arm or behind the ear. These areas are sensitive enough to show reactions but discreet for client comfort.
Instruct the client to leave the test area untouched for 24 to 48 hours, observing for any redness, itching, swelling, or discomfort. During this time, the client should avoid applying other products, scratching the area, or exposing it to heat, as this could interfere with the results. After the waiting period, the esthetician should check the area, note any reactions, and record them carefully in the client’s file. Proper documentation ensures that the test is reliable and can guide treatment decisions. It also provides a record for future visits, allowing the salon to track any sensitivities over time. This simple procedure prevents potential allergic reactions, protects the client, and demonstrates the salon’s commitment to safety and professionalism.
Communicating the patch test to clients
How patch testing is presented to clients can influence their experience. Some clients may see it as unnecessary or inconvenient, but framing it positively makes a big difference.
Explain it as a precaution for their comfort and safety, for example:
“This test is a quick way to make sure your skin reacts well to the product before your full treatment. It helps us keep your skin safe and smooth.”
Clear communication is essential. Estheticians can reinforce that patch testing is a standard procedure used in all professional salons. When clients understand the purpose and benefits, they feel reassured rather than inconvenienced. Patch testing becomes a sign of care and professionalism rather than an optional step. Educating clients about patch testing can also enhance their trust in the salon. Some estheticians share this information during consultation calls, appointment confirmations, or even through social media posts. This transparency shows clients that the salon prioritizes safety and creates a more professional image overall.
What to do if a client reacts to a patch test
Even with careful testing, some clients may show a reaction. In such cases, immediate action is necessary. Wash the area gently with mild soap and lukewarm water, and apply a soothing, calming product, like a post-wax oil or aloe-based treatment. Document the reaction in the client’s file, noting the type and severity, to inform future treatments.
Depending on the reaction, estheticians may recommend an alternative wax or aftercare product. In more serious cases, clients should seek medical advice before proceeding with any treatments. Handling reactions professionally reassures clients, prevents further complications, and strengthens trust in the salon.
Patch testing also allows estheticians to adjust techniques or products for sensitive clients, ensuring that everyone receives a safe and comfortable experience.
Common mistakes to avoid in patch testing
Even experienced estheticians can make mistakes during patch testing. Skipping the test to save time is the most common mistake and increases the risk of allergic reactions. Not recording client consent or the results of the test is another serious mistake, as it may create liability issues. Other common mistake include applying the test too close to the actual treatment or using a different product than the one intended for the session. Inconsistent procedures can also lead to unreliable results.
The key to effective patch testing is consistency, careful application, and accurate documentation. When performed correctly, patch testing protects clients, enhances the salon’s reputation, and demonstrates the esthetician’s professionalism.
Final thoughts – safety first in professional waxing
Patch testing is a small but essential step that makes a significant difference in client safety and salon professionalism. It ensures that clients are protected from allergic reactions, builds trust, and reinforces the salon’s reputation.
For waxing services, using high-quality products like Black Coral Wax during patch testing ensures professional results and minimal irritation. However, the most important elements are careful attention, proper timing, and clear communication with clients. A salon that prioritizes patch testing shows that it values client safety and comfort above all else. This practice is not just a safety measure - i t is a mark of professionalism, care, and expertise. Clients who feel safe, respected, and well-informed are more likely to return and recommend the salon to others, creating a loyal client base and a thriving business.
