|First off, good for you for knowing that daily sun protection is a must, even on a cloudy day. You’re already off to a great start when it comes to taking good care of your skin. |
Applying multiple SPF products is a good practice, but here’s the reality: SPF numbers do not add up to give you more protection. You WILL get the highest sun protection factor you have applied, however. So in this example, you’ll get an SPF 25 from your moisturizer.
