I had a few questions emailed to me from readers after this feature the other day on the hows and whats of COVER FX’s Custom Cover Drops so I wanted to address them here. When it comes to HOW to apply it, I consider this product kind of an at-home beauty experiment; a DIY, if you so please, in the sense that you should apply it however is comfortable for you.

Here are a few different ways I’ve tried: above I'm showing a drop next to some plain sunscreen on a tray I use to mix paints on when I’m crafting. On a side note, literally hours after I took this photo, I got Beauty Blender’s Sur.face Pro, which is great because it’s made just for mixing makeup! Now I have a tray for each.

So you can mix your Custom Cover Drops with your product on a tray or add the drop/s to a product in your hand, or if you’re mixing it with a primer, I’ve also put a squirt of product and a few drops on the back of my hand and then mixed them together with the brand's Liquid Foundation Brush ($38). But I nixed that after I started thinking about how the products might just be sinking into the back of my hand so I switched back to mixing on the tray.

So I guess it’s up to you on HOW you want to mix the drops and a face product together.

The other question I received was with WHAT can you mix it with? I’d say 99% of your face products! Like I’ve been mixing a few drops with products I’ve been trying in the past few weeks - Cover FX’s Mattifying Primer with Anti-Acne Treatment ($38/1oz @ sephora.com), Murad’s Invisiblur Perfecting Shield Broad Spectrum SPF 30 ($65/1oz @ nordstrom.com and ulta.com) and Tarte’s Maracuja Neck Treatment ($49/1.7oz @ tartecosmetics.com and sephora.com). And the pigment drops blend in beautifully and tints them all my shade!

If you have any other questions about Cover FX’s new Custom Cover Drops, I’ll be having a Twitter Party tomorrow, Friday, March 20^th from 3pm to 4pm EST, just to talk about them! Join the chat by using the hashtag #dropportunity and looking forward to talking to you then! And I'll be giving away some bottles of the Custom Cover Drops.
