How to safely test a new beauty product before using
By Cynthia Lodite, July 17, 2026Trying a new lipstick, foundation, face cream or serum can be exciting, but not every beauty product is suitable for every skin type. Some cosmetics may trigger irritation, redness or allergic reactions, especially if they contain ingredients your skin is sensitive to.
Before adding a new product to your skincare or makeup routine, experts recommend taking a few simple precautions to protect your skin.
Testing a new beauty product may take a little extra time, but it can help prevent painful skin reactions and protect your overall skin health. Performing a patch test, reading ingredient labels, introducing products gradually and purchasing from trusted retailers are simple steps that can make a big difference.
The World Health Organization notes that substandard and counterfeit consumer products can pose significant health risks because they may not meet established safety standards. Similarly, the American Academy of Dermatology advises consumers to patch-test new skincare products and discontinue use immediately if irritation develops.
Healthy skin starts with informed choices. Before trying the latest beauty trend, take a few minutes to test the product safely your skin will thank you for it.
Start with a patch test
One of the safest ways to test a new beauty product is by performing a patch test. This involves applying a small amount of the product to a discreet area of skin, such as the inside of your forearm or behind your ear.
Leave the product on for 24 to 48 hours, unless the instructions say otherwise, and monitor the area for signs of irritation such as redness, itching, swelling, burning or blistering. If your skin reacts, wash the area immediately and avoid using the product on your face.
According to the American Academy of Dermatology (AAD), patch testing is especially important for products that remain on the skin, including moisturisers, serums, sunscreens and makeup.
Read the ingredient list
Before purchasing any cosmetic, take a few moments to check the ingredient list. If you know you are allergic or sensitive to certain ingredients, avoid products that contain them.
People with sensitive skin may want to be cautious with products containing high concentrations of fragrances, alcohol or certain preservatives, as these can sometimes cause irritation.
Buying products with clear ingredient labels from reputable manufacturers also makes it easier to identify the cause of a reaction if one occurs.
Introduce one product at a time
Avoid changing your entire skincare routine at once. If you begin using several new products together and your skin reacts, it becomes difficult to identify which product caused the problem.
Dermatologists recommend introducing one new product every one to two weeks so you can monitor how your skin responds before adding another.
Check the expiry date
Using expired cosmetics can increase the risk of skin irritation and bacterial contamination. Before applying a new product, check the expiry date and inspect the packaging for signs of damage, leakage or tampering.
Avoid products with unusual odours, changes in colour or texture, as these may indicate the product has deteriorated.
Buy from trusted retailers
Counterfeit cosmetics are becoming increasingly common in many markets. These products may contain harmful ingredients or be manufactured under poor hygiene conditions.
To reduce your risk, buy beauty products from authorised retailers, pharmacies, reputable supermarkets or the official websites of trusted brands. Be cautious of products sold at unusually low prices or in packaging that looks poorly printed or lacks an ingredient list.
