Have you ever tried the Amore Pacific Treatment Enzyme Peel? If not, it's a powder that foams on your skin to exfoliate with absolutely no grit or harsh acid, it just kinda dissolves dead skin. It's pricey, so if you're interested, try to get a sample before you buy. I don't know how sensitive your skin is after using Retin-A, but if it's pretty hardy, try using a weak AHA on clean skin. That's kind of hardcore and may be something you have to work up to. In terms of gentleness, I would say the Amore Pacific is actually more gentle than a washcloth, and an AHA is definitely less gentle than a washcloth. Another idea is squalane, if you haven't already ruled it out. It's not actually an oil, more of a dry essence, and it didn't break me out back when I was still breaking out if I even looked at an oil. I found that it made an amazing primer for my foundation and added an extra glow. It hydrated my skin so we'll that the flakes nearly disappeared and foundation went on like a dream. Fortunately, it doesn't require a huge outlay, as The Ordinary offers an inexpensive vegan option. One product I'm falling in love with right now is the Dr. Jart+ Tiger Grass Color Correcting Treatment. I got a sample with my points, and I'm pretty amazed that it actually does what it promises. It's like a combination of calming cream, green color correcting primer, and a high end BB cream. It feels like a calming cream going on, is really soothing, and changes from light green to your skin tone. It doesn't look heavy like foundation, it just evens out skin and hides redness, actually soothing the red skin as it hides it. It also has sunscreen in it so you don't have to worry about getting sunscreen on your flaky, sensitive skin. I find that putting extra on redder areas doesn't make it look heavier or cakey, it just gives more cover. I wouldn't say that the final effect is a super polished airbrushed foundation perfection, but it's definitely a lot more even and together than nothing or a caked on mess. The only thing about that is that I don't know how versatile the color change technology is, meaning how dark it will go. I have fair skin and it works great, but deeper skin tones may not be covered. Korean brands are not known for their wide shade ranges. I wish I had some secret surefire method to impart to you, but I never found one. There must be some trick makeup artists use, so maybe try hitting up the closest Sephora store and asking their staff. I know that I have seen some people on TV with flaky skin absolutely pancaked over, so it may be a challenge even for pros. The more makeup you have on, the more evident it will be if a flake comes off and leaves a blank spot. Honestly, when mine was bad I used a brush and circular motion, figuring at least all sides of the flakes were even. Remember that the worst will pass, the flakes won't last forever, and keep your eye on the prize--years of ageless skin that doesn't break out! And play up your gorgeous eyes so you don't notice the flaking as much. Nobody notices our flaws as much as we do. And if anyone does notice the flaking and is rude enough to say so, tell them you're allergic to cheap perfume and to stand further away from you.
