Scared of aging but mainly because my skin burns in the sun easily. 

I know that the spf+ is how long the protection lasts and not how much it blocks.  so anything with 30 and 50 spf for me would be fine.
Something I can find online would be nice but I'm open to going to my local health beauty stores.
Also looking for moisturizer, my skin can look dull and flaky at times.
Budget: no more than rm50 for each item.
