Sunscreen functions by blocking, reflecting, or scattering the harmful UV rays of the sun, which can damage your skin and raise your chance of developing skin cancer. There are two types of UV rays: UVA and UVB. UVA rays cause early aging and contribute to the growth of skin cancer by penetrating deeply into the skin. Sunburns are caused by UVB radiation, which are also linked to skin cancer.

There are two types of UV rays: UVA and UVB. UVA rays cause early aging and contribute to the growth of skin cancer by penetrating deeply into the skin. Sunburns are caused by UVB radiation, which are also linked to skin cancer.

There are two primary categories of sunscreens: chemical and physical. Physical sunscreens deflect and scatter UV rays away from your skin, whereas chemical sunscreens absorb UV photons and turn them into heat. Although physical sunscreens are frequently favored since they do not include any potentially dangerous chemicals, both types are efficient at protecting your skin. The downside to some physical sunscreens is that they can be more opaque or whitening on your skin due to their mineral formulation.

There are a few key factors to consider when selecting the best sunscreen for your needs. The sun protection factor (SPF) rating, which reveals the degree of protection against UVB rays, is the most significant. The protection is increased by a high SPF. A sunscreen with an SPF of 30 or higher is generally advised by dermatologists.

Consider the water resistance as well, particularly if you intend to swim or sweat a lot. Look for sunscreens with the phrase "water-resistant" and take notice of how long they hold up when exposed to moisture. No sunscreen is truly "waterproof" but some are more water resistant than others.

The chemicals in your sunscreen are yet another crucial factor. Avoid sunscreens with compounds like oxybenzone and octinoxate, which may be hazardous to coral reefs and other marine life. Alternatively, check for sunscreens made with natural components like zinc oxide and titanium dioxide.  Which sunscreen do we recommend?  There are many, like professionally dispensed ZO and EltaMD or over the counter options like Neutrogena.  But Dr. Molenda says to find any SPF30+ sunscreen you’re comfortable wearing daily, and that is what he recommends.  This isn’t the red carpet.  It doesn’t matter “who you’re wearing”, it just matters that you’re wearing it.

It's crucial to apply sunscreen appropriately if you want to get the full benefits. Apply sunscreen generously over all exposed skin, and reapply every two hours, as well as right away after swimming or perspiring. Don't forget to give your face, neck, ears, and the tops of your feet extra consideration.

What if you don’t wear sunscreen?  The effects of not using sunscreen are severe and long-lasting. Age spots, wrinkles, and other signs of premature aging can all be brought on by sun exposure. Long-term sun exposure also raises your risk of getting skin cancer, including melanoma, which can be deadly.  It is also important to note that sun protection is essential throughout the entire year, not just in the summer months or on sunny days. UV rays can penetrate windows and clouds to cause sun damage even when indoors or on an overcast day. 

In conclusion, including sunscreen in your skincare routine is crucial. You can protect your skin from the damaging effects of the sun's UV rays and lower your risk of developing skin cancer by picking the right sunscreen and applying it correctly. Incorporate daily facial sunscreen use into your morning routine and remember to reapply when outside for long periods or sweating.  Your skin will appreciate it!
