Sunscreen is the number one most important part of a skin care regimen. At the cellular level sun light in the form of UV or ultraviolet radiation decreases the production of collagen and elastin, the proteins in skin, which makes it look smooth and plump, and at the same time also increases production of the proteins that degrade collagen and elastin because of the inflammatory process caused by the sun damage. If that is not enough the radiation from the sun can damage your DNA permanently and that is what leads to –> cancer. Even small amounts of sun that you would get through a window or from walking to your car can add up to significant skin damage. If you are interested about the science of sunscreen and the different types see my previous post here.
So literally sun = worse looking skin.
So what should you do next?
I would recommend SPF of at least 30. Obviously any SPF is useful. SPF 30 covers about 97% of the UVB radiation, the math is difficult for most so I will spare you the details but it involves calculus #nerdalert. When looking for sunscreen look for ones that say “broad spectrum” as those will also protect against UVA radiation. I know confusing.
Personally, I use a mineral type, which contains zinc, on my face every morning. This type does NOT have to be reapplied unless washed off and it is typically not greasy. I put it on after I brush my teeth in the morning after washing my face and don’t worry about it for the rest of the day. This works for daily wear such as walking to work, driving and my daily run. If I find my self outside a bit more than I want I also carry a brush on powder zinc/titanium sun screen in my backpack as well which takes 5 seconds to apply and cuts down on shine if it is a hot day. #twobirdsonestone
For any other exposed parts of my body I typically use a chemical type sunscreen with active ingredients such as avobenzone. First, it is inexpensive compared to the mineral type and I don’t mind a greasier formula that typically comes from this sunscreen category. The second benefit is it works as a lotion, keeping skin soft and well hydrated. If I know I will be outside for an extended period of time, such as at the beach, I will often also add a chemical type on my face for some added protection. Reminder this type NEEDS to be reapplied to work properly, but it is a small cost to not have wrinkles and significantly reduce your risk of cancer.
Recap:
- Sun = Bad, increased wrinkles, makes skin less smooth, and causes cancer
- Use sun screen daily of at least SPF 30. Use as directed some need to be reapplied
- Look for mineral sun screen or a chemical type that is “Broad spectrum”
