be careful with acne prone skin [SEP] i really like yes to products but if you have sensitive acne prone skin you should be careful with this conditionerafter using this conditioner for a few days i noticed that it was causing me to break out on my back and neck i like everything else about the conditioner it leaves my hair feeling really soft and protects my hair in the dry winter months if you suffer from acne prone skin make sure you are using a cleanser after this conditioner to reduce the chance of forming a breakout
