Is pigment dissolving solution good for removing age spots?

Generally, the effectiveness of pigment-dissolving solutions for removing pigmentation spots depends on the type of spot. Such solutions may have some effect on superficial epidermal pigmentation; however, they are usually ineffective for dermal pigmentation or melasma and may even cause skin problems. Detailed analysis is as follows:

If the spots are superficial epidermal pigmentation such as freckles or sunspots, pigment-dissolving solutions can help break down superficial pigment particles and promote their metabolic removal, thereby lightening the spots. However, concentration and frequency of use must be strictly controlled to avoid skin irritation, redness, stinging, or other discomfort.

For dermal pigmentation such as nevus of Ota or nevus of Hori, or hormone-related melasma, pigment-dissolving solutions cannot effectively reach deeper pigment layers or regulate endocrine function. As a result, they not only fail to remove the spots but may also disrupt the skin barrier, worsening pigmentation or triggering inflammatory reactions.

In daily skincare, it is recommended to practice proper sun protection to reduce UV-induced pigmentation; choose gentle whitening products containing ingredients like vitamin C and niacinamide to assist in fading spots. Additionally, avoid using spot-removal products indiscriminately to prevent skin damage.
