I'm on my second tube of Dior Addict Lip Maximizer High Volume Lip Plumper, which must mean that I like it. Or, more accurately, while I like MintGlaze FX from Cover FX better, the wide availability of Dior Addict Lip Maximizer (Sephora and any Dior counter, including the one 5 minutes away from my house) ensured that when I found myself scraping the last few drops of lip treatment from my tube, I just went out and picked another Dior one.
I usually avoid lip plumpers because they irritate my lips too much. I prefer products that volumize the lips through the use of hyaluronic acid and intense hydrating. The exception is mint and menthol that tend to be milder (for me. Some people are very sensitive to them). I love the one by CoverFX (haven't tried the tinted ones, though) and find mild enough to apply as a lip treatment and not just for plumping. Dior Addict Lip Maximizer High Volume Lip Plumper is similar, though it's significantly stronger on the tingling front.
Dior Addict Lip Maximizer High Volume Lip Plumper takes about 15 minutes to do its thing and fill the lips with hyaluronic sphere that make them soft and plump. You apply it with the doe foot applicator before starting your makeup and by the time the rest of your face is finished your lips are ready for color, including matte lipsticks. The plumper can also be mixed with a color product on the back of your hand and then painted on with a lip brush, as shown to me by a Dior makeup artist. Do take note that if your lips have even the smallest crack it's going to sting. The color, by the way, is completely sheer and doesn't add anything to my lips. If you're extremely pale you might see some pink there, but I wouldn't know.
Bottom Line: Have I mentioned that I'm on my second tube?
Dior- Dior Addict Lip Maximizer High Volume Lip Plumper ($31, an 0.2oz tube, which actually makes it a much better deal than the $22 for 0.1oz of Cover FX) is available at the counters and from Sephora.
