If you could only use one skincare product for the rest of your life, dermatologists overwhelmingly agree: it should be sunscreen. No retinol, no vitamin C serum, no professional treatment comes close to the anti-aging effect of consistent daily SPF.
What UV Does to Your Skin
Up to 90 percent of visible skin aging — wrinkles, dark spots, loss of elasticity — is caused by UV exposure, not by getting older. UVA rays penetrate clouds, windows, and even light clothing. They reach your skin every single day, year-round, and they break down collagen and elastin over time.
The Denver Factor
Denver sits at 5,280 feet above sea level. For every 1,000 feet of elevation, UV radiation increases by about 4 to 5 percent. That means Denver residents receive roughly 20 to 25 percent more UV exposure than people at sea level. If you live here and skip sunscreen, the math is not in your favor.
How to Choose the Right SPF
Use a broad-spectrum SPF 30 or higher every day. Broad-spectrum means it blocks both UVA (aging) and UVB (burning) rays. Apply it as the last step of your morning routine, after moisturizer. Reapply every 2 hours if you are outdoors.
The Sunscreen You Will Actually Wear
The best sunscreen is the one you use consistently. If you hate greasy formulas, try a lightweight mineral or chemical sunscreen designed for the face. Many modern formulas are invisible, non-comedogenic, and sit beautifully under makeup. Your esthetician can recommend one that works with your skin type.
