A patch test is an easy way to predict whether your skin will react negatively to a new product. It is always advisable to perform a patch test before including a new product in your routine.
It doesn’t take much time, but it can save you from future hassle.
How do I do a patch test?
- Apply a small amount of the product on a clean area of skin on the inside of the wrist or on the upper forearm
- Do not wet the area where you applied the product
- Rinse the product after 24 hours
If you notice any changes, redness, itching, burning or irritation during the test, rinse the area thoroughly and discontinue product use.
Note that the test is only intended to determine the initial irritant reaction and is not a 100% guarantee that the situation will be the same on other parts of the body. If you are worried about starting to use a new product, consult a dermatologist before use.
