The Amount of Sunscreen You Should Use for Maximum Protection

用多少防曬霜才能獲得最大防護

Many of us have probably experienced squeezing out what we think might be way too much sunscreen, and so we desperately try to smear the extra on the closest person, or shove some back into the bottle (with no luck). As it turns out, we may actually need all of that...and more.

許多人可能都有過這樣的經(jīng)歷：認為擠出的防曬霜有點太多了，于是拼命試圖將多余的涂到最近的人身上，或者吸一些回瓶子里(比較不幸)。事實證明，實際上所有擠出來的這些我們可能都需要……甚至更多。

According to this article by the Skin Cancer Foundation, the general recommendation is 2 milligrams of sunscreen per square centimeter of skin. In plainer terms， that’s about one ounce of sunscreen, or enough to fill one shot glass (or two tablespoons). What’s more, you should save one “nickel-sized dollop” for the face alone.

根據(jù)皮膚癌基金會的一篇文章，通常建議每平方厘米肌膚涂抹2毫克的防曬霜。更直白地說——就是約一盎司的防曬霜，或足以填滿一個矮玻璃杯(或兩湯匙)的量。更重要的是，你應(yīng)該為自己的臉單獨留下“一個硬幣大小的”一塊防曬霜。

If you use a non-cream type sunscreen, such as a spray, apply enough until an even sheen appears on the skin. The trouble with sprays is, you can’t really know whether you’ve used enough of it. The American Academy of Dermatology suggests using liberal amounts, but avoiding spraying directly into your face. If you must use the spray on your face, spray your hands first and then apply that to your face.

如果你使用一種非油脂型防曬霜，如噴霧型的，要涂抹至皮膚上顯現(xiàn)出光澤才夠。噴霧型的問題在于，你無法知道是否已經(jīng)使用了足夠的量。美國皮膚病學(xué)會建議用量自由，但要避免直接噴到臉上。如果你必須在臉上噴灑，先噴到手上，然后在涂抹至臉部。
