Why SPF is Nonnegotiable (Even in Winter or Indoors)

When most people think about sunscreen, they think about beach days, summer vacations, or avoiding a bad burn at the pool. But here’s the thing: SPF isn’t just a “summer” product. It’s a year-round, nonnegotiable step if you actually want to see results with your skincare.

Let’s break down why:

1. Sunlight doesn’t take the winter off. Even when it’s cloudy or cold, up to 80% of UV rays still reach your skin. And yes, they’re still doing damage — breaking down collagen, causing pigmentation, and keeping redness and post-acne marks hanging around longer than necessary.

2. Indoor light is sneakier than you think. Blue light from your computer, phone, and even overhead lighting can trigger pigment and contribute to premature aging. So if you’re working inside all day and think you’re safe, you’re not.

3. SPF makes your other products work better. If you’re investing in serums, facials, or treatments to fade dark spots, smooth texture, or reduce fine lines, skipping SPF is like pressing the undo button every morning. Without protection, your skin just keeps creating the same issues you’re trying to fix.

And here’s the kicker. A lot of the ingredients that do the heavy lifting (like retinol, vitamin C, and exfoliating acids such as glycolic or lactic acid) also make your skin more sensitive to UV damage. So if you’re using those and not protecting your skin, you’re basically setting yourself up for irritation and undoing the progress you just made.

4. SPF boosts your results now

. Yes, SPF prevents skin cancer and long-term damage, but it also helps keep your skin brighter, firmer, and more even right now. It’s not just about “one day in the future.” It’s about your skincare routine actually working today.

So what’s the move? Apply SPF daily even if you’re just running errands or sitting inside all day. Look for at least SPF 30, reapply if you’re outside for long periods, and make it the last step in your morning routine (before makeup).

It’s not optional. It’s skincare insurance. And honestly? It’s the cheapest, most effective anti-aging product you’ll ever own. Shop GlyMed SPF here to find the formulas that fit your routine and keep your skin glowing.
