Sunscreen Guide: How to Choose and Use the Right SPF

If you could only do one thing for your skin, it should be wearing sunscreen daily. Sun exposure is the single biggest cause of premature aging, pigmentation, melasma and dark spots — and it's also the most preventable. Yet sunscreen is the step most people skip or get wrong.

Why Sunscreen Matters So Much

UV rays damage collagen, trigger excess pigment and worsen conditions like melasma. Daily sunscreen prevents tanning and dark spots, slows wrinkles and fine lines, and protects the results of treatments like peels and laser. Without it, pigmentation treatments simply won't hold.

How to Choose the Right Sunscreen

• SPF 30 or higher for everyday use; SPF 50 for outdoor or sun-intense days.
• Broad spectrum (protects against both UVA and UVB) — look for 'PA+++' or higher.
• Match your skin type — gel or matte for oily/acne-prone skin, cream for dry skin.
• Non-comedogenic if you are acne-prone, so it doesn't clog pores.

How Much and How Often

• Use about two finger-lengths for the face and neck — most people apply far too little.
• Apply 15–20 minutes before going out.
• Reapply every 3–4 hours if outdoors or sweating.
• Wear it indoors too — UV passes through windows and screens emit some light.

Common Sunscreen Mistakes

• Applying too little, which drops the real protection well below the label SPF.
• Skipping sunscreen on cloudy days — up to 80% of UV still gets through.
• Forgetting ears, neck, hands and lips.
• Not reapplying after the morning application.
