Sunscreen FAQs - How and When to Apply Sunscreen
To better understand the importance of SPF and sunscreen we asked Kayte Epperly, Scientific Communication Liaison at L’Oreal Research & Innovation US Skin Care Development, some important information on how to use sunscreen effectively in your beauty routine.
When do we need to wear SPF?
Ideally you should wear it at all times, but especially if you are outdoors, even if it is an overcast day.
Are all sunscreens created equal? What are the different SPF factors, and the differences between UVA/UVB protection?
Sunscreens in the USA need to meet specific guidelines set forth by the FDA. SPF（防晒系数）指防晒霜阻挡 UVB 射线的能力。SPF 30能阻挡大约 97% 的 UVB 射线，SPF 值越高，阻挡 UVB 射线越多。这个数字与需要重新涂抹防晒霜的频率无关。
UVA rays also known as “aging rays” can prematurely age your skin, cause wrinkles and age spots. They are able to pass through glass windows.
UVB rays also known as “burning rays” are primary cause of sunburn and cannot pass through window glass.
Broad Spectrum means that the sunscreen will help protect against UVA and UVB rays.
The type of sunscreen you use comes down to personal preference and the format you select should be one that you would use regularly.
What is the recommended level of sun protection for daily wear?
美国皮肤病协会建议日常使用最低的 SPF 30值或较高值。
How much sunscreen should you apply?
Sunscreen should be applied liberally ensuring that all exposed areas are covered. To fully cover most adult bodies you need about 1 ounce (or a shot glass full).
What is the best way to apply & reapply sunscreen?
It is recommended to apply sunscreen at least 15 minutes prior to going outdoors for the sunscreen to absorb into your skin. 应每 2 小时补抹一次或者去游泳或大量出汗后需重新涂抹防晒霜。
防晒霜应涂抹在干燥的肌肤上并整体按揉。To be sure you don’t miss any spots, you can apply in front of a mirror or ask someone to assist on hard-to-reach areas.
