Finding the right sunscreen can make a big difference in your skin’s health as you age. Ultraviolet (UV) rays can cause sunburn, premature aging, and increase your risk of skin cancer, so a good sunscreen is essential—especially for adults 40 and older who want to maintain healthy, protected skin.
When shopping for sunscreen, the first thing to look for is an SPF (sun protection factor) of 30 or higher. This level blocks about 97% of harmful UVB rays, which are the main culprits for sunburn and DNA damage. While higher SPFs are available—and may be recommended for people at higher risk—you’ll get the biggest benefit simply by applying correctly and reapplying often. Experts recommend reapplying every two hours and after swimming or heavy sweating to keep your protection strong.
Choosing between lotion, spray, gel, or stick sunscreens usually comes down to what you enjoy using. Cream-based options are good for dry or mature skin, while gels or sprays can make application easier for some. “The best sunscreen is ultimately the one you’ll use every day,” dermatologists often say.
Be mindful of the ingredients, especially if you have sensitive skin, allergies, or special health considerations. Some common ingredients, like avobenzone or octocrylene, can occasionally cause skin reactions. Try testing new products on a small area first if you’re concerned about irritation. For environmentally conscious consumers, mineral sunscreens (those with zinc oxide or titanium dioxide) tend to be less harmful to marine life than some chemical formulas.
Broad-spectrum protection is a non-negotiable feature. Unlike older formulas, broad-spectrum sunscreens shield your skin from both UVA (associated with skin aging and wrinkles) and UVB rays (which cause burning). UVA rays can even penetrate window glass, making daily sunscreen a smart choice—even indoors.
If you spend time swimming or working up a sweat, look for water-resistant formulas. While no sunscreen can be labeled as “waterproof,” water-resistant products will last longer during activity, but still need to be reapplied every two hours or after getting wet.
Wondering whether to choose mineral or chemical sunscreen? Both can effectively guard your skin. Mineral options use natural blockers like zinc oxide, making them ideal for those with sensitive or allergy-prone skin. Chemical sunscreens often go on clear and feel lighter—but some people may find they cause irritation. Hybrid formulas, combining both mineral and chemical ingredients, are also available.
Selecting a sunscreen suited to your skin type is also important, especially as skin changes with age. If your skin is dry, moisturizing sunscreens offer comfort and extra hydration. If you experience breakouts, look for oil-free or non-comedogenic varieties. Those with sensitive or mature skin often benefit from fragrance-free, hypoallergenic products.
Skin tone also plays a role in sunscreen needs. Individuals with lighter complexions are at greater risk for sunburn and may want products with a higher SPF. Those with deeper skin tones might find mineral sunscreens leave a white cast, but new tinted or sheer versions are widely available. “No matter your skin tone, broad-spectrum SPF 30 or higher is best for lasting protection,” experts emphasize.
Applying sunscreen properly makes all the difference. Put it on 15 minutes before heading outside and don’t skimp—most adults need about an ounce (enough to fill a shot glass) for full-body coverage. Don’t forget easily missed areas: tops of feet, ears, part lines in hair, and lips. Be sure to reapply every two hours, and check that your sunscreen isn’t past its expiration date, as old products can lose effectiveness.
The bottom line: Regular use of the right sunscreen is one of the simplest, most effective ways to maintain healthy, youthful skin as you age. Choose a formula you love to use daily, tailored to your skin’s needs. If you have questions or unique skin concerns, a board-certified dermatologist can help you find your perfect match.
