Firstly waxing shouldn't make your hairs grow back thicker or darker but could irritate the skin a bit so if you have acne I suggest you don't do this. Though at supermarkets you can buy a special cream that gets rid of any hairs ( but best for fine hairs) but it only lasts as long as shaving. This cream is very gentle on skin if left on for the correct amount of time usually 3-5 minutes. Hope this helps
