2. Use a tiny quantity of the product.

Put a tiny bit of the skin care product—roughly half the size of a pea—directly in front of your ear. It is convenient to watch and observe any possible reactions from this place. Don’t spread the product beyond of the specified test area; instead, apply it uniformly.

3. Keep an eye on the skin

Observe this section of skin for a full day. After a day, if you still experience redness, itching, or irritation, wash the affected area with a mild cleaner. The expert advises choosing a fragrance-free one because it is less prone to irritate skin.

4. Conduct more patch testing.

You can use the product if there are no responses on your skin. A second round of patch testing can be conducted if you would want to try the product again and there is any slight irritation. To test whether adding a moisturizer to the product can help it be tolerated better, do so.

You should avoid the product if you experience burning or redness in the affected region, since this indicates an allergy.
