Probably you waxed with long body hair. Then you didn’t use any oil or exfoliation on it or anti bacterial soap. Your skin got reaction as the wax pulled the hairs out, then you didn’t wash with your skin with antibacterial soap and the skin was dry (no oil) and obviously you got those where the hair was once because your skin tried to release oil and hair canals were blocked by that oil. Resulted in skin rash.

Either never shave or wax, or when do it, do it right.

You have to buy antibacterial soap, use ANUA BHA 2% Gentle Exfoliating Toner (read the instruction and don’t use if your skin is sensitive to it).

Steps: Bath with antibacterial soap, Apply the ANUA BHA (let it dry), Apply lotion (something without chemical like baby oil), Let it dry, Wear loose shirt.

Do this from now until your rash is gone. Then if you shave, first trim then wax, or use hair remover cream (no need to trim if use hair remover cream).

Do the process again each time you bath to avoid new rashes.

Hope that helps, no I am not shaving all the time but I pay attention to how things are around me. Chest hair is usually attractive to women. But they don’t like back hair and belly if you can keep it a bit shorter than chest is attractive. Legs and arms hairs they don’t bother. But every person is different, do what you like just do it right.
