Why Mixing SPF Lotions Can Lead To Negative Effects!

Posted on | July 2, 2009 | 2 Comments

It can seem nearly impossible to find a high numbered SPF and excellent moisturizer rolled into one mega product. When talking about the face, moisturizers with an SPF of 30+ can feel greasy and have very little moisturizing effects. This is because the product is mainly full of effective SPF ingredients, leaving little room for all those yummy moisturizing ingredients (which can often interfere with the SPF). With this known, it can also seem tempting to mix your two favorite products! I’ve always advised against it and The Beauty Brains agree with me! Mixing moisturizers and SPFs can dilute them to the point of being ineffective against UV rays. Certain ingredients used in moisturizers and body lotions can inhibit the way sunscreen ingredients work on the skin. I suggest applying your favorite sunscreen first then wait 7 to 10 minutes to let it absorb before applying another product on top of it.

I’ve also been asked about mixing two different sunscreens to achieve greater protection. Don’t do it. Mixing an SPF 15 with an SPF 20 does not equal an SPF 35. It’s not only wasteful, but you’re likely to have just concocted an ineffective product!

Finding a 2in1 product (SPF with moisturizer) has already been tested for it’s effectiveness. So as long as you feel hydrated, you’ve got it all! What 2in1 product have you found to be both moisturizing and protective?
