Pigmentation is a condition that can be compared to skin getting a different tone in some areas. It may be caused by environmental factors like the sun, changing hormonal levels, or it is sometimes the skin's natural characteristic. A cream infused with ingredients such as niacinamide or kojic acid would help to lighten the pigmentation. Remember to wear sunscreen every day to improve your skin health.

Chicken skin is a condition whe­re your skin feels bumpy, and rough, like­ sandpaper. Keratin buildup blocks hair follicles, causing this. Using mild cle­ansers helps. Moisturize ofte­n. Gentle exfoliation smooths bumps. Lactic acid or ure­a products reduce roughness. It's common but usually improve­s gradually. 

It depends on the extent of the damage. If the wound is mild, cleaning it with a mild soap and water will promote healing. For serious cases, you should head to a dermatologist or a plastic surgeon with expertise in breast reconstruction. It is also wise to seek medical assistance to avoid possible complications.
