Detailed answer

A patch test can be performed by a dermatologist to check for contact dermatitis or allergic reactions to specific skincare products. During the test, small amounts of the product are applied to your skin under adhesive patches, usually on your back. After 48 hours, the patches are removed, and any resulting irritation or redness is observed. This helps identify if you have any allergies to the tested products. It's important to consult with a dermatologist for an accurate diagnosis and proper testing procedure. Keep in mind that patch tests may only detect immediate allergic reactions and may not identify all types of skin sensitivities or irritations.
