Hi monicakm,
There are some really good instruction videos on youtube about how to apply tretinoin.
This is what I do to avoid irritation. I saw my derm and she wanted me to use it on clean, dry skin, but that just did not work for me. Too much irritation (peeling, senitive skin)
So, here is what I do:
Cleanse
Moisturize (Neutrogena Gel Moisturizer)
Let moisturizer dry
Apply a pea size amount of Tretinoin.05%
Dot the Tretinoin all over the face (2 dots on forehead, a dot on each cheek, a dot on the chin, then rub it all in - think more like dividing the pea-sized amount of Tretinoin over the skin evenly)
Pea size is about the size of the top half of the top part of your index finger.
As for results, it can take at least up to 6 months or longer, and your extra wrinkles may be from your skin getting too dry on the Tretinoin.
You could stop for a few days then introduce it slowly by only using it a couple days a week, and then adding on a day a week at a time. (This is what I did)
Also, use that sandwich method of moisturizer, Tretinoin, moisturizer.
I agree with everyone who mentioned sunscreen in the day, and follow some of these dermatology experts on youtube. They have some great tips about using and applying Tretinoin.
I have a feeling you need to just back off on usage and go a bit slower in introducing it on the skin. Patience is key with tretinoin. Think of it more like a marathon than a sprint. HTH
