What SPF should I use daily?

Dermatologists recommend SPF 30 as the daily minimum — it blocks 97% of UVB rays — but SPF 50 (98% blockage) is recommended for outdoor activities, high-altitude exposure, or if you have hyperpigmentation or melasma. SPF above 50 offers diminishing returns. More important than SPF number is reapplication: any SPF must be reapplied every 2 hours of direct sun exposure. Chemical sunscreens absorb UV; mineral sunscreens (zinc oxide, titanium dioxide) physically reflect it — both are effective when applied correctly (1/4 teaspoon for the face).

What is the difference between chemical and mineral sunscreen?

Chemical sunscreens (avobenzone, octinoxate, octisalate, homosalate) absorb UV radiation and convert it to heat. They are lightweight, sheer, and invisible on all skin tones, but can cause irritation for sensitive or rosacea-prone skin and must be applied 15–30 minutes before sun exposure. Mineral sunscreens (zinc oxide, titanium dioxide) sit on the skin surface and physically deflect UV. They work immediately, are less irritating, reef-safe, and better for sensitive skin, but can leave a white cast — though modern micronized formulas have largely solved this.

Can I use the same sunscreen on my face and body?

Yes, but face-specific sunscreens are formulated to be non-comedogenic (won't clog pores), lighter in texture, and often include skincare actives (niacinamide, antioxidants). Body sunscreens prioritize large-area coverage at lower cost and are often thicker or greasier. For acne-prone skin or daily wear under makeup, stick with a face-specific formula. For outdoor activity where you're applying head-to-toe, a body sunscreen on the face is fine. Look for "broad spectrum" on all sunscreen labels — this confirms both UVA and UVB protection.

Best Sunscreens for Melasma: Iron Oxide + High SPF Picks

Melasma needs more than UV protection — you need iron oxide for visible light. Here are the SPFs that actually help fade dark patches.

The short answer

Best sunscreens for melasma contain iron oxides (which block visible light, a major melasma trigger) plus SPF 50+. Top picks: EltaMD UV Clear Tinted, Colorescience Sunforgettable, La Roche-Posay Anthelios SX, and Avène Mineral Tinted SPF 50.

If you have melasma and use clear chemical sunscreen, you’re missing 30-40% of the protection you need. Here’s why iron oxides matter and which sunscreens have them.

Why visible light matters for melasma

The short answer

Melasma is triggered by both UVA/UVB and visible light (especially blue light from screens and sunlight). Standard sunscreens block UV but transmit visible light. Iron oxides in tinted sunscreens block visible light, which is critical for melasma management.

The science:

UVA/UVB: ~50-60% of melasma triggers
Visible light (400-700nm): ~30-40% of melasma triggers
Infrared: smaller contribution

A clear chemical SPF blocks UV but lets visible light through. Iron oxide tinted sunscreens block both.

What to look for

The short answer

For melasma: SPF 50+, broad-spectrum, contains iron oxides (or “tinted” mineral formula), reapply-friendly. Bonus: niacinamide or kojic acid for additional pigment management. Avoid clear chemical-only sunscreens.

The melasma SPF checklist:

✓ SPF 50 or higher
✓ “Tinted” or contains iron oxides
✓ Broad-spectrum (UVA + UVB)
✓ Reapply-friendly texture
✗ Clear chemical-only formulas
✗ SPF under 30

The full melasma SPF protocol

The short answer

Apply a tinted SPF 46+ every morning, reapply every 2 hours when outdoors, and use a brush-on powder SPF for midday touch-ups over makeup. Combined with vitamin C in the morning and tretinoin at night, this manages melasma without prescription lightening agents.

The full daily protocol:

Morning: Cleanse → vitamin C (SkinCeuticals C E Ferulic) → tinted mineral SPF 46+
Midday: Brush-on powder SPF (Colorescience Sunforgettable)
Evening: Cleanse → tretinoin (only if on script) → moisturizer
Indoors: Continue SPF if near windows or screens for >2 hours

What about hydroquinone?

For severe melasma, hydroquinone (via Musely or compounded prescription) is the next step. But it shouldn’t be used for more than 3-4 months at a time. Iron oxide SPF is the daily foundation that prevents melasma from worsening regardless of treatment.

Frequently asked

Can I use clear sunscreen if I have melasma? +

It's better than nothing but not optimal. Visible light still triggers pigment. Tinted with iron oxides is the proper choice.

How long until I see melasma fade? +

With consistent tinted SPF + vitamin C + tretinoin: 3-6 months for noticeable fading, 12+ months for significant improvement.

Do I need to wear SPF indoors? +

Yes if you're near windows (UVA penetrates glass) or screens for extended periods. Visible light from devices contributes.
