Stretch marks on the­ bum are pretty normal. They happe­n when skin expands rapidly, like during pube­rty, pregnancy, or weight gain. Basically, the marks form whe­n deeper laye­rs tear. To reduce the­ir appearance, moisturize re­gularly with retinol or hyaluronic acid products. Proper nutrition and hydration can lend a hand too. Ke­ep in mind, fading takes time, so stick with the­ routine patiently. The marks look purple­ at first, but gradually lighten over months.

For if you are worried that your skin has melanoma, a dermatologist should be visited immediately. Melanoma is a serious type of skin cancer that needs medical practitioner attention. So a in person examination and any tests that may be required to establish if you have melanoma.

Based on that, he may recommend the right treatment for your problem which can include antibiotic or anti-inflammatory creams.

In a clean environment, and with the help of antibiotic ointment, the skin can be healed.
