How to Choose

• SPF and PA Rating: Always look for SPF50 and PA++++ for maximum protection against UVB and UVA rays, especially in tropical climates.
• Water and Sweat Resistance: Essential for Thailand’s heat and humidity – choose a label that says “water-resistant” for 40 or 80 minutes.
• Texture and Finish: Lightweight gels or milks work best for oily skin, while creams suit dry skin. Avoid greasy formulas that clog pores.
• Ingredients: Check for alcohol content if you have sensitive skin. Fragrance-free and non-comedogenic options are safer for acne-prone skin.
• Price and Availability: Some sunscreens are only sold online or at specialty stores. Consider your budget and how easy it is to repurchase in Thailand.
• Reapplication Ease: A sunscreen that doesn’t pill under makeup or feel sticky makes it easier to reapply every two hours, which is crucial in tropical sun.
