The Best Sunscreen for Melasma in 2021

Melasma is a skin condition characterized by the appearance of brownish or grayish patches of skin. The condition is common among women.

Although melasma generally does not signify any underlying condition nor pose any harm, those who are affected are often bothered by how it appears. Treatment involves use of the best sunscreen for melasma.

The best sunscreen for melasma: Physical vs. chemical sunscreens

Other than preferring a broad spectrum sunscreen – one that blocks both the deep-penetrating UVA and the surface burning UVB radiation – you must also know the difference between physical and chemical sunscreens.

Chemical Sunscreens

Chemical sunscreens are sunscreens that have chemical actives such as oxybenzone, octinoxate and homosalate.

These chemicals transform the UV in heat, which is a much less harmful by-product.

Physical Sunscreens

Physical sunscreens literally block out UV The most common physical sunscreens are mineral sunscreens made with only Titanium Dioxide or Zinc Oxide or both.

Other botanical active sunscreen ingredients are only just starting to be manufactured and distributed.

Since melasma is also caused by harsh chemicals, physical sunscreens are your top options

This is supported by a study published in the Journal of Investigative Dermatology. The researchers were able to establish that physical sunscreens are effective in shielding skin from visible light.

Between physical sun blockers, Titanium Dioxide and Zinc Oxide, a study recommends Zinc Oxide is the more effective ingredient. The study also emphasizes that recent use of nano-sized Zinc Oxide provides even better coverage and protection against UV.

My Favorite Sunscreens For Melasma

1. Eltamd UV Clear SPF 46

  • Effective sunscreen and moisturizer in one
  • Contains niacinamide which aids in proper skin nourishment
  • Non-greasy
  • Fragrance-free
  • Paraben-free


  • Contains Octinoxate is an endocrine-disrupting chemical (EDC) and bears high risk for irritation. This EDC mimics estrogen which switches on and off several critical body processes. It also bioaccumulates which means that it can be passed on from mother to child and is not degraded into simpler forms. At higher concentration, octinoxate is toxic.
