The problem of pigmentation is particularly distressing. From freckles to hormonal spots, and then to age spots and melasma, various types of pigmentation not only affect appearance but also make the skin look dull and lifeless, impacting personal charm. Dark and light spots, along with acne scars, make the skin uneven, and even concealer can struggle to cover them up. The presence of pigmentation is related to the accumulation of melanin, and as we age, skin elasticity decreases, pores become enlarged, and issues like uneven texture may worsen.
