a2o Lab Locked Eye Primer

This eye primer is amazing. I absolutely love it. Effortless blend ability. No patchiness very good buy, I recommend.

I had to give this a shot, I couldn't pass up the price! I thought no way will it perform as well as the higher priced eye primers I have used but it EXCEEDED my expectations, it went on well, and was grippy but not heavy or sticky and just as long lasting as my higher priced primers! I would definitely recommend this product, I would LOVE to see these in MORE colors! I bought all 3 different on and was hoping the "pinkish" one was pink but it really didn't have a very strong pink hue to it and I didn't notice a big difference using the shimmer.

Yes, A20 products come at a higher price tag but the quality is reflected in that price, with pro performance and formulas. I don't ever regret paying a little more (and still way less than even drugstore cosmetics) for things I can confidently put in my kit, as they compete with expensive professional products.
This is a better product by far than the last Miss A eyeshadow base and my favorite offered here.
The shimmer base is an inventive option, but I will get the most use out of the pinkish sheer! I use it UNDER my eyes, though! Eyeshadow primer is the best prep for under eyes where creasing is just as much a concern and the fact this is brightening, silky and emollient is perfect. I apply sparingly (after hydrating well and letting the serum soak in, using the recent under eye serum from Miss A in fact!) It's not that it won't work for eye shadow, but for very oily lids I still prefer Sigma's cream stick eye primer and Miss A has nothing like it at this time, all the eyebases other than the tacky one are the silky silicone types. But while our eyelids are producing tons of oil, our under eyes are doing the opposite, so this product helps compensate. Haven't tried the "nude" but it may be a better choice for the lids for most light/medium skinned people, as it seems to be a warmer shade which would help correct and balance purple and blue.

My eyelids are very oily, so I don't think it's a flaw of the formula, but this creased a fair amount. My Urban Decay Primer has done the exact same thing, though. This acts exactly the same way and has the same priming power. Great overall!

Smooth and keeps eye shadow in place all day.
