Especially people with sensitive skin, it is necessary for you to test patch a new product.  Of course, also for people who have a sour situation to products in the past.   There are a number of allergens in products that can cause contact dermatitis.

Some ingredients may cause a a reaction more than others such as products with synthetic dyes and fragrances, sulfates, phthalates as well as products with high concentration of acids.  We are not saying the mentioned are bad; it is really got to depends on quantity added.  

If you have acne-prone skin, ingredients to look out for should include coconut oil and butter, cocoa butter, lanolin, and isopropyl palmitate.

How do you patch test ?

There are some places on the body that we can patch test.

 For example, if you’re testing for your face, apply a tiny amount at on the side of your neck or the jawline.   If you’re testing for your elsewhere on your body, apply behind your knees, your belly, or your upper arms.

There should be no other products on the skin so that you can properly test this product. Reactions will typically occur with 24 hours, but may take up to 72 hours for some products.

Reactions to look for:

Pay attention on the reaction.  

BAD REACTION : This will be quite awful when Your skin will likely look red, bumpy or splotchy, and it will feel itchy or painful. In this case, you should absolutely discontinue use and either toss the product out or hand it off to a friend who may have better luck.

Breakouts: Any pimples, blackheads, or whiteheads. These can usually be seen or felt If your skin is breaking out, it’s best to discontinue use.
