Introduction

Sunscreen can help prevent the formation of melasma between the eyebrows to some extent. Melasma development is associated with multiple factors, including ultraviolet radiation, genetic predisposition, endocrine disorders, and changes in estrogen levels. Prolonged exposure to sunlight can increase the activity of melanocytes due to ultraviolet radiation, leading to excessive production of melanin, which results in pigmentation and the formation of melasma.

Under normal circumstances, sunscreen can prevent the formation of melasma between the eyebrows to some extent. The detailed analysis is as follows:

Melasma formation is associated with multiple factors, including ultraviolet radiation, genetic factors, endocrine disorders, and changes in estrogen levels. Prolonged exposure to sunlight causes ultraviolet rays to increase melanocyte activity, leading to excessive melanin production, pigment deposition, and the development of melasma.

The primary function of sunscreen is to protect the skin from UV damage by absorbing or reflecting UV rays, thereby reducing the skin's exposure to ultraviolet radiation. Using sunscreen can effectively reduce UV damage to the skin and decrease the formation of pigmentation spots, including melasma between the eyebrows. It is recommended to choose a sunscreen with SPF 30 or higher to provide adequate sun protection.

When applying sunscreen, ensure that the area between the eyebrows as well as the entire face are thoroughly covered for comprehensive skin protection. In addition to using sunscreen, wearing sun hats, sunglasses, and other sun protection tools can also help prevent the formation of melasma between the eyebrows.

What are the differences between melasma and freckles?

Under normal circumstances, melasma and freckles differ significantly in terms of etiology, affected body sites, lesion morphology, age of onset, and triggering factors. Melasma is primarily associated with endocrine disorders, ultraviolet radiation, genetic factors, and mental stress, and results from increased activity of melanocytes leading to skin pigmentation; freckles, on the other hand, are mostly caused by autosomal dominant inheritance.

Is pigment dissolving solution good for removing age spots?

In general, the effectiveness of pigment-dissolving solutions for removing pigmentation spots depends on the type of spot. For superficial epidermal pigmentation, pigment-dissolving solutions may be somewhat effective. However, for dermal pigmentation or melasma, such solutions are usually ineffective and may even cause skin problems. In daily skincare, it is recommended to use sun protection to reduce UV-induced stimulation of pigmentation.
