Best sunscreen for uneven skin tone
La Roche-Posay Anthelios Melt-In Milk Sunscreen SPF 60 is the most effective pick for uneven skin tone. Sun exposure triggers melanin production, which darkens existing spots and patches, so daily broad-spectrum protection is the foundation of any plan for a more even tone. This lotion uses avobenzone, homosalate, octisalate and octocrylene to absorb UVA and UVB rays, it stays water resistant for 80 minutes, and it's made for face and body. The ethical pick, Badger Unscented Sunscreen Cream SPF 30, is certified cruelty free. It relies on zinc oxide, a mineral filter that protects against both UVA and UVB, in a base of sunflower oil and beeswax. Mineral creams can leave a slight white cast, so rub it in well. The table below compares price and time to results. Whichever you choose, apply it every day, including cloudy days, and reapply at least every two hours outdoors.

| Cruelty free and all natural | Badger Unscented Sunscreen Cream SPF 30 | US$17.99 (100 mL) | 0 | US$17.01 less than the most effective pick, same time to first results |
Why it works
Broad-spectrum sunscreen (mineral and chemical filters)
Sunscreen, used with shade and clothing, helps lower the risk of skin cancer and early skin aging. Broad-spectrum products protect against both UVA and UVB rays, and SPF measures protection from sunburn. Dermatologists recommend broad-spectrum SPF 30 or higher, reapplied at least every two hours and after swimming or sweating. The evidence is strong: in a randomized trial of 903 Australian adults, daily sunscreen users showed no detectable increase in skin aging over about 4.5 years. Mineral filters (zinc oxide, titanium dioxide) are often recommended for sensitive skin. Some chemical filters are absorbed into the body, but absorption alone does not mean harm.
Dark spot and tone-evening ingredients (tranexamic acid, licorice extract, kojic acid, vitamin C)
Several over-the-counter ingredients can gradually fade dark spots, including vitamin C, kojic acid, azelaic acid, glycolic acid and retinoids. Evidence is mostly small studies, often in melasma rather than other dark spots: licorice extract has very few clinical trials, and kojic acid still needs better studies. Tranexamic acid has reduced stubborn melasma in studies, mostly when taken as a prescription pill. Results are slow, usually 3 to 12 months, and spots can return. Daily sunscreen, ideally tinted with iron oxide to block visible light, is essential. Irritating products can themselves cause new dark spots, so stop anything that burns or stings.
