Unless you are an infant < 6 months, everyone should use a #sunscreen daily. Even those working indoors are exposed to ultraviolet radiation, especially if you sit near windows. #SPF or Sun Protection Factor, measures the sunscreen's ability to prevent #UVBfrom damaging skin. If it takes 20 minutes for unprotected skin to start turning red, using an SPF 15 prevents reddening 15 times longer (5 hours). In percentage terms, SPF 15 filters out 93% of UVB rays, SPF 30 filters out 97% and SPF50 filters 98%.

Choose one with broad spectrum protection - only those with SPF of >15 protects against #skincancer and early #skinageing . Physical sunscreens contain natural ingredients, #zincoxide and #titaniumdioxide . They sit on top of skin, deflecting sun's rays, like a shield. Generally thicker and whiter in texture, they can leave an opaque, white cast on skin but tend not to trigger reactions on skin. Our pick is:

Skinceuticals' #PhysicalFusionUVDefense - I've used this for years and everyday, I still fall in love with it:) Ultra sheer with no chemical filters, this physical #sunblock is weightless. Translucent iron oxide spheres evenly disperse within the only the 2 #FDA approved physical filters (UVA and UVB), providing ultimate protection and universal radiance. It glides onto skin and blends into ANY natural skin tone. Highly versatile for cold or humid weathers, it leaves no greasy or suffocated feel yet keeps skin hydrated. For oily skins, choose #Sheer PhysicalUVDefense

Biologique Recherche's #ProtectionUV - its current formulation stands at #SPF25 but soon to come in 50! A silky, pearlescent liquid with no smell, its unique selling point lies in Triple Shield Complex ( UVA+UVB+infrared) and is free of nanoparticles. Its richer, thicker consistency makes it more hydrating, soothing (think protective veil) and water-resistant.

In hot, humid #Singaporeand for daily use, it's Physical Fusion Defense for me. In cold, wintry, arid climates, Protection UV.
BLOCK UP please.
