If you’re doing serums, moisturisers, and fancy face masks—but skipping SPF—you’re missing the most important step. No matter the weather, the season, or your skin type, SPF is the real hero of any skincare routine.

But why exactly is SPF so crucial, and what happens when you skip it? Here’s everything you need to know, plus the best SPFs to slot into your skincare lineup today.

What Does SPF Actually Do?

SPF (short for Sun Protection Factor) protects your skin from UVB rays, which are the rays that cause sunburn and increase your risk of skin cancer. Broad-spectrum SPFs go a step further and protect against UVA rays, which penetrate deeper into the skin and contribute to premature ageing, pigmentation, and loss of collagen.

In short: SPF = prevention against both short-term and long-term skin damage.

The Anti-Ageing Secret You’re Overlooking

Did you know that up to 90% of visible skin ageing is caused by sun exposure? Fine lines, wrinkles, dark spots, and uneven texture are all linked to UV damage over time. While serums and actives help repair, SPF is what stops the damage from happening in the first place.

No matter how advanced your skincare routine is, without sun protection, you’re just undoing your hard work.

But What If It’s Cloudy or I’m Indoors?

Here’s the truth: UV rays can penetrate clouds and windows, meaning your skin is still exposed—even when you’re not outside basking in the sun. That’s why dermatologists recommend applying SPF 30 or higher every single day, rain or shine.

Even blue light from screens has been linked to oxidative stress and hyperpigmentation. Some modern SPFs now include blue light filters, giving your skin an added layer of protection in today’s tech-heavy world.

Can’t I Just Use Makeup with SPF?

It helps, but it’s not enough. Most makeup products with SPF don’t provide high or broad-spectrum coverage—and you'd need to apply a thick, unrealistic amount to get the labelled protection. Think of SPF in makeup as a bonus, not a replacement.

Your skin deserves a standalone SPF product applied as the final step in your skincare routine, before makeup.

What to Look for in a Good SPF

  • Broad-spectrum protection (UVA + UVB)

  • SPF 30 or higher

  • Lightweight and non-comedogenic for daily wear

  • Skincare-infused formulas with extras like niacinamide or hyaluronic acid

  • Tinted SPF if you want a sheer coverage boost

Final Thoughts: The Best Skincare Investment? SPF.

There’s no single product that will do more for your skin than sunscreen. Whether your goal is anti-ageing, glowing skin, or preventing future damage, daily SPF is your foundation.

So if you’re not already using it daily, now’s the time. Your skin will thank you—not just today, but years from now.
