So essentially it is a clear semi-liquid gel that you smooth over a clean face to minimize your pores. I didn't dig into the science of it all, but it would appear to essentially just fill those pores. Sounds scary, I know, but I have yet to break out or have any kind of reaction to this product so it must fill them without clogging. Don't ask me how that works.
For the $5.59 price tag, this is a pretty good little product. I've always had problems with large pores (thanks, genetics) and my mistreatment of my acne when I was younger certainly didn't help. My cheeks in particular are a problem area, especially around the front of my face. Below you actually can see a difference. This was without any foundation over the top, so you will have to excuse the redness of my one cheek. However if you zero in on the pores, I certainly think they are much less visible on the side with Baby Skin on it.
Overall, I wouldn't go as far as saying this is a miracle product. It does make foundation a little slippery, and I do think it makes it wear off a little quicker since the makeup is resting on top of the gel instead of the skin or a primer. As a stand-alone face product, though, I'm in love. Days "without makeup" are a little less rough now, and a repurchase isn't out of the question. Now to try and save up for the Benefit product to try a comparison! Those of you who have tried both- is it worth it?
