Originally people used 'sunblock' for the strong, thick kind that sits on top of your skin and stops the light physically — the white paste you see on a lifeguard's nose — while 'sunscreen' meant the kind that soaks in and filters the light. Today most people, and most shops, use the two words for the same thing, and 'sunscreen' is the more common word.

Originally本來 people used 'sunblock'人們用'sunblock' for the strong, thick kind指那種厚重的 that sits on top of your skin會停在皮膚表面 and stops the light physically用物理方式擋光——the white paste you see on a lifeguard's nose就是你在救生員鼻子上看到的那種白色膏狀物——while 'sunscreen' meant the kind而'sunscreen'指的是那種 that soaks in and filters the light會滲進皮膚、過濾光線的. Today今天 most people, and most shops大部分人、大部分店家, use the two words for the same thing都把這兩個字當同一件事用, and 'sunscreen' is the more common word而'sunscreen'是比較常見的說法.

Note that no product really blocks all of the sun, so in many countries (America, Europe) companies are now not allowed to print the word 'sunblock' on the bottle; you will still hear people say it, but you will see 'sunscreen' or 'sun cream' on the label. In Britain 'sun cream' is the everyday word.
