It’s that time of year when sunscreen becomes top of mind—and while summer sun safety is crucial, daily sun protection should be a year-round habit. Even on cloudy days or during cooler months, UV rays are still at work. These rays accelerate aging, worsen pigmentation, and damage skin at a cellular level—even if they’re not strong enough to cause a visible burn. In fact, sunscreen is the most effective (and affordable) anti-aging product you can use. NOT ALL SUNSCREENS ARE CREATED EQUAL Sunscreens vary widely in ingredients, protection levels, and formulas. While SPF is often seen as the most important factor, its impact is frequently misunderstood. Here’s a quick breakdown: • SPF 15 blocks approximately 93% of UVB rays • SPF 30 blocks around 97% • SPF 50 blocks roughly 98% No sunscreen blocks 100% of UV rays—99% is the maximum, regardless of marketing claims.
MINERAL VS. CHEMICAL SUNSCREENS
FINDING YOUR PERFECT FORMULA Gone are the days of greasy, chalky mineral sunscreens. Modern formulas are lightweight, blend easily, and don’t leave a residue.
There are two main types of sunscreen: mineral (also called physical) and chemical. Mineral sunscreens use zinc oxide and/or titanium dioxide to reflect UVA and UVB rays off the skin’s surface. They are ideal for sensitive skin and less likely to cause irritation. Chemical sunscreens absorb UV rays and convert them to heat, which is released from the skin. These formulas are more commonly associated with reactions or breakouts. If you have sensitive skin, rosacea, pigmentation concerns (like melasma or sun spots), or simply want the safest protection, mineral sunscreens are your best choice, especially those with more than 10% zinc oxide for broader UVA/UVB coverage.
Some favourites include:
Face: Tizo AM Replenish (tinted), IS Clinical Powder Sunscreen (great for reapplication over makeup) Body: Tizo Ultra Zinc, Tizo Mineral Stick, IS Clinical Eclipse Other trusted brands: Colorescience, EltaMD, La Roche-Posay, Eminence As someone with rosacea, pigmentation issues, and very sensitive skin, I’ve tried them all. While I have my personal favourites, the best sunscreen is the one you’ll use daily and reapply consistently.
ALREADY HAVE SUN DAMAGE?
TINTED OR UNTINTED?
It’s never too late. Sunscreen helps prevent further damage and slow the progression. Treatments like topical antioxidants, IPL, and laser resurfacing can help reverse the signs— many with minimal to no downtime. Bottom line: sunscreen isn’t just for summer. It’s your skin’s daily shield and a crucial step in maintaining a youthful, healthy glow.

Both provide excellent protection, but tinted
sunscreens offer additional defense against visible and blue light (from screens and indoor lighting), which can exacerbate pigmentation. Tinted formulas also help even out skin tone. Untinted versions may leave a white cast but are just as effective.
