Different skin conditions require different approaches; for instance, various types of hyperpigmentation require individualized treatment plans. For example, if you have a tendency to freckle, wearing sunscreen is the best course of action. For skin spots, melasma, age spots, and post-inflammatory hyperpigmentation (PIH) products containing Vitamin C are going to help your skin fade with the appearance of dark spots. But other ingredients like retinol work better for PIH, sun, and age spots.
