Sometimes skin pigmentation can manifest as a lighter shadow around patches of skin on your face – that means it’s probably treatable by some home regimens such as lightening creams, and acid-based products like kojic acid, salicylic acid, or Vitamin-C infused products.
But there will also be times that the pigmentation has gone pretty deep that you will need help from experts – that’s where skin resurfacing, chemical peel, microdermabrasion, and the like come in. It’s always best to consult your dermatologist so they can determine which process will work best for your skin type & skin condition.
