Want beautiful hair and blemish-free skin? Then you need to become a detective—actually a cosmetic ingredient detective.
The truth is that some ingredients may cause problems for you and not for other people. At the end of this article, we’ve included a list of ingredients that have been shown to cause acne. Or you can purchase a book on cosmetic ingredients for future research.
Try to Keep it Simple
If you have acne, do not use products that add any oil to your skin or hair. Ingredients labels don’t underline the acne-causing ingredients. When looking at products and acne treatments, always look for “non-acne” or “non-comedogenic.” Not oil-free, because it may still contain ingredients that cause breakouts. Stay away from isopropyl myristate, oils, and silicone, petrolatum, PVP, CVP and copolymer ingredients. Also sodium lauryl sulfate and ammonium lauryl sulfate are ingredients to avoid.
Wash and condition your hair before you wash the rest of your body. Do this to wash off any residue that hair products may leave on your skin. (Just think how hard it is to get grease off of dishes, you normally need to wash it several times to be grease-free.) It’s the same with hair products—they will leave a residue that can cause breakouts IF YOU ARE PRONE TO ACNE. Really clean the skin well to rid it of any product residue.
