Most people use too little and that is why it does not work. Use half a teaspoon for your face and a shot glass worth for your full body to get the protection level shown on the bottle.

Use Enough Product

Ears neck back of hands and lips are the most commonly missed spots. These areas are just as exposed to UV rays as your face so always make sure they are covered.

One morning application is not enough. Sunscreen breaks down after two hours of sun exposure so reapply regularly especially if you are outdoors sweating or after swimming.

Up to 80 percent of UV rays pass through clouds. Skipping sunscreen on overcast days is one of the most common mistakes that leads to pigmentation and premature ageing over time.

Sunscreen should always be the last product before makeup. Applying it under moisturiser or serum reduces its effectiveness and prevents it from forming the protective layer your skin needs.

Sunscreen only works when applied correctly and consistently. One small change in how you apply it can make a big difference in your skin over time.
