Lashes and SPF
If you are an extension wearer you shouldn't feel like you need to sacrifice your skin health for those long beautiful lashes! Lets break down finding the perfect SPF that will protect your skin while keeping your lashes looking fabulous!
UVA v. UVB
Lets first start with a little sun science. The rays from the sun have different levels of intensity. UVB rays are shorter rays of ultraviolet light and UVA rays are longer/stronger rays. The way I remember the difference between these is UVB= Burn and UVA=Aging. Basically, the UVB rays are going to penetrate the top surface layers of your skin and give you that nice sunBURN. UVA rays are going to hit your skin harder and penetrate deeper into your skin, which you might not see effects of right away, but they are going to impact the way your skin AGES.
Chemical v. Physical(Mineral)
Lets now learn to categorize SPF into two types.
-Chemical SPF is going to absorbs the rays and releases it as heat and its generally going to require more ingredients in order to provide Broad Spectrum protection from UVA and UVB rays. Chemical SPF will take 15-30 minutes before it starts to "work" and will need to be reapplied more frequently but I definitely think a chemical SPF is much more appropriate for days swimming or when you are exercising heavily.
-Physical(Mineral) SPF is going to deflect the rays entirely and it will naturally protect against both types of UV rays. Physical could mean physically putting on a hat and blocking the rays or using the minerals Titanium Dioxide and Zinc Oxide to block the rays. Those ingredients are going to sit on top of the skin to provide that physical block. Because the mineral SPF ingredients are resting on-top of the skin, rather being absorbed into the skin like a chemical SPF, it can be washed away easily and sometimes leaves a powdery finish on the skin. No wait time is needed when using a physical(mineral) SPF.
SPF: Sun Protection Factor
This is the number that you see on your bottle. The ideal number range is SPF 30- SPF 50. This number indicates how long before you would need to reapply. If you see a sunscreen using a number larger than 50 it is just a marketing technique.
Now what you have been waiting for...
Lashes and Sun Protection
When wearing lash extensions its important to avoid oil based products around the orbital bone to help protect the adhesive bonds. Even if you are going out in the sun for only 30 minutes on an overcast day you NEED to be wearing your sunscreen. The first big tip is to select your sunscreen based on your needs for the day. As I mentioned above, if you are going to be swimming or heavily exercising, go with a chemical broad spectrum SPF opposed to a day watching your child play soccer where a mineral SPF would be just fine.
Next, apply at the right time and reapply often. If you choose to wear a chemical SPF be sure to apply early enough for the product to absorb prior to playing in the sun.
And most importantly, choose a either a MATTE SPF. This means that it is going to absorb the oil and prevent oils traveling toward the lash line.
