Glow Responsibly: The SPF Rules for Retinol & Exfoliation

Glow Responsibly: The SPF Rules for Retinol & Exfoliation

If you’ve recently added exfoliating acids or retinol to your skincare routine, congrats! You're on your way to smoother, brighter, more even-toned skin.

But there’s one non-negotiable step that must go hand-in-hand with these powerful ingredients: daily sunscreen.

Below, we break down why sunscreen is essential when using exfoliants like AHAs and BHAs, or retinoids like tretinoin and retinol, and what can happen if you skip it.


What Happens to Skin When You Use Exfoliants or Retinol?

Exfoliating acids (like glycolic acid, lactic acid, and salicylic acid) work by dissolving dead skin cells on the surface of your skin. Retinoids, on the other hand, speed up cell turnover and stimulate collagen production from within. Both leave your skin looking fresher, clearer, and more youthful over time.

But here’s the catch: they also make your skin more sensitive to the sun.

This happens because:

  • Your outermost layer of skin is thinner (and thus more delicate)
  • Your skin’s natural barrier is temporarily compromised
  • You’re exposing “new” skin cells to UV rays before they’ve had time to strengthen

 



Why Sunscreen Is Crucial

When your skin is in this more vulnerable state, unprotected sun exposure can lead to:

  • Increased risk of sunburn
  • Hyperpigmentation or dark spots
  • Redness and irritation
  • Slower healing after breakouts
  • Accelerated aging
  • Reduced effectiveness of your active skincare products

In other words: skipping sunscreen can undo all the progress you're trying to make with your retinol or acid exfoliator.

 



Pro Tips for Combining Sunscreen with Retinoids or Exfoliants

  • Apply sunscreen every morning, even if it’s cloudy or you’re mostly indoors.
  • Wait 15 minutes after applying sunscreen before heading outside.
  • Double-cleanse at night to fully remove sunscreen, makeup, and pollutants.
  • Reapply sunscreen every 2 hours if you’re spending time outdoors.

 



Bottom Line: Sunscreen Is Not Optional

If you’re investing in products like glycolic acid, salicylic acid, or retinol, don’t let UV rays sabotage your results. Wearing sunscreen daily is the single best way to protect your skin while using actives, and to maintain long-term skin health and radiance.
