The Best Sunscreens for Melasma Management: Protect and Treat Your Skin

One of the primary triggers of melasma is exposure to UV radiation, which can exacerbate existing pigmentation and cause new patches to form. This makes sun protection a crucial component of any melasma management plan. However, not all sunscreens are created equal, and some may worsen your melasma by irritating your skin or failing to provide adequate protection.

Does sunscreen for melasma work? Let’s find out!

Melasma is a common skin condition characterised by dark patches of hyperpigmentation that usually appear on the face. It’s often triggered by sun exposure, making it crucial to use sunscreen regularly.

The two types of UV rays that cause damage to the skin are UVA and UVB. UVA rays are responsible for skin ageing, while UVB rays are responsible for sunburns. Both types of rays can also worsen melasma by triggering melanin production, causing dark patches to become more prominent.

Sunscreen helps prevent melasma by reflecting or absorbing UV radiation before it can penetrate the skin. Chemical sunscreens contain organic compounds that absorb UV rays, while physical sunscreens contain inorganic compounds that reflect UV rays. Both types of sunscreens can provide broad-spectrum protection against UVA and UVB rays.

Nowadays, blue light (high-energy visible light) and infrared rays have also been found to play a role in triggering melasma. Therefore, an ideal sunscreen should provide broad-spectrum protection against UVB, UVA, visible light (including blue light), and IR radiation.

Choosing sunscreens containing physical blockers such as zinc oxide or titanium dioxide is essential for melasma treatment. These ingredients create a physical barrier on the skin’s surface, reflecting and scattering UV rays away from the skin. Physical sunscreens are less likely to cause irritation or allergic reactions and are preferred over chemical sunscreens for people with melasma. Additionally, sunscreens with an SPF of at least 30 are ideal.
