Although you can buy longer needles for at-home use, it’s best to stick to a derma roller with a needle length of less than 0.5 millimeters.

　　Any needle above this length runs a higher risk of damaging skin and is best left to a pro.

　　Don’t forget to do your research. Only buy from trusted sites and stores, and check that the product has been properly sterilized before it reaches you.

　　If you do decide to use a serum with your derma roller skin, choose one that will benefit your face when it penetrates your skin.

　　Some serum ingredients can cause an adverse reaction if sent further into the skin.

　　Steer clear of potentially irritating retinol and vitamin C.

　　These will seal in moisture and assist with the regenerative process that can improve skin tone and texture.
