What is everyone's favorite concealer? I'm thinking liquid over cream.......
I know you specifically mentioned liquid concealer and I am sorry, I haven't used anything that are my "holy grails". For myself, I use the Benefit Erase Paste mentioned. (The medium shade is perfect for 85% of people, I would guess.) It is the salmon color that many famous makeup artists swear by. I use this to cover my undereye circles. You can often find a kit that includes a mini of this at Sephora online with a couple other deluxe sample items. (Nice way to try a few products...)
For my makeup kit (I do bridal, some fashion show/shoot makeup) I rely on the HD creme corrector shade palette by Grafobian. I use mini wax sticks as a palette knife, pick up a tiny bit of product and I haven't ever needed to reach for any other concealers. The greeny shade is perfect to mix with the skin tone and cover blemishes. (I recently had a bridesmaid that had several RED blemishes - covered! I little bit goes a long way and I should probably toss it before I will ever run out. The Graftobian website has a minimum purchase, but I have found this at Camera Ready Cosmetics online and, just now, even Amazon.
Good luck with your quest. I love to see what everyone uses!
