Talk to Dermatologist on Skin Dryness And Flakiness

I was having mild acne and extreme sun tanning and hyper pigmentation. I used gl*c*l*c a*id thrice a week which made my skin extremely dry and flaky. Didn't use moisturizer properly nor used sunscreen. My skin used to be extremely oily but it has become very dry now. I have stopped using everything only applying fresh aloe vera gel, moisturizer for sensitive skin and sunscreen since yesterday. (Prescribed by my dermatologist when i visited her for skin concerns). She has moved out so can't visit her now.

Now the problem is extreme dryness and flakiness. There's burning on my face whenever i apply moisturizer. Should i do the icing to make it better? Also suggest something to revive the skin barrier.

Thank you in advance
