How to prevent redness and waxing bumps?
Cold compress or apply ice
After waxing your skin becomes sensitive. It is important to apply cold compress. This is what I usually prefer. It helps to settle the irritation. Alternatively, you can rub an ice cube over that area.
Moisturize
After waxing, you should apply an antiseptic cream. The natural moisturizers are aloe vera, tea tree oil, etc which soothes the skin. I usually apply aloe vera gel which gives a soft texture to my skin.
Check menstrual cycle
You should always check your menstrual cycle. Waxing around your date is big NO NO because your skin is most sensitive during that time. It causes redness along with a lot of additional pain. So why put yourself through that?
Avoid tight clothes
Tight clothes can cause irritation so I usually wear loose clothes after my waxing session which lets my skin breathe.
