Eucerin sunscreen zinc oxide12/23/2023 ![]() As long as my blackout curtain is drawn, I am not reapplying.ĭr. ![]() My routine now is to apply my vit C serum followed by sunscreen (1/4th tsp to face and neck) and only reapply at noon if I go outdoors after my run or if I am next to my uncovered glass window. However, I run in the mornings for ~40 minutes. I am not wearing sunscreen every minute when I am indoors since I have blackout curtains which block all UV at my workstation. By default, glass keeps you safe from UVB. I've listened to both Shereen Idriss and David Lim (both dermatologists) cover this issue on their instagram live feeds and they agreed that if you are working near windows, you are still getting exposed to UVA and thus need protection. This can occur when a product is older when it is exposed to high temperatures, or simply because the formula is not stable. watery/oily liquid) for a sunscreen lotion or cream, this means the product is separating and that is will likely no longer meet the quoted SPF or PFA. While some products are designed to be shaken vigorously just prior to use, if you notice a change in texture, grittiness, or separation (e.g. Sunscreen products should be smooth and uniform in look and appearance. Products in the USA which have been evaluated for both UVA and UVA effectiveness will state ‘broad spectrum” on the package while outside the USA you may see a PFA (UVA protection factors) quoted alongside the SPF. UVA (ultraviolet A) rays are also important to consider since they contribute to sun damage, premature wrinkling, and burns. The SPF refers to UVB (ultraviolet B) rays and when labeled as SPF 30, it generally means that it would take you 30 times longer to burn than if you wore no sunscreen at all. Since sunscreens are considered drugs by many regulatory agencies, when you see a SPF (sun protection factor) quoted on a package, it means that a company has submitted evidence to prove its product meets the requirements for the stated value. These particles like to stick together so how well they stay suspended and how uniformly they cover when applied the skin are key. UV filters like zinc and titanium are actually very small particles of various sizes that are dispersed in a carrier liquid (lotion, emollient, spay). Reapplication is critical since products can be worn or washed off throughout the day. Most dermatologists recommend that you buy a product that you know you will use since protection against the damaging rays of the sun is a top priority to help prevent skin cancer. When evaluating sunscreens, it is next to impossible to look just at the filters being used to decide which are more or less effective.
