Nate, I can't find the link for this quote, but when I read it I copied and pasted it. It may have come from fafner55 in one of the dasatinib threads.
I haven't tried this, but maybe you?
"Topical Dasatinib Treatment to Improve Skin"
Topical dasatinib treatment of UVB-exposed SKH1 hairless mice reduced the total tumor burden (ie, benign tumors, atypical benign tumors, squamous cell carcinomas) per mouse. It might be effective in improving skin in humans.

Since 120 mg dasatinib taken orally resulted in minor sloughing of my skin ( the bulk of sun damaged skin remains) I can assume that 120 mg / body weight is a minimum starting dose for topical treatment.
Ratioing 120 mg / 70 kg body weight to the approximate weight of my skin (8.8 kg) gives 15.1 mg dasatinib for my entire skin.
I found that 1 tbsp (15 gm) of body lotion is needed to cover my entire body. That amount, mixed with 15 mg Dasatinib is my starting point.
Building on other experience, I ground and added 400 mg honokiol. Unlike many other polyphenols, honokiol is white and does not stain, making it a good candidate for increasing the effects of dasatinib.
For the base I used either Cerave lotion or DMSO 70%.
* Cerave lotion is well absorbed by the skin and does not feel greasy.
* DMSO 70% penetrates better than lotion and can be applied to lips and hair.
After much experimentation I found this mixture to potently treat sun damaged skin. It is best to start slowly, such as
* Apply once then wait a few days. Skin will redden and will improve without peeling. One application will visibly improve sun damaged skin.
* After several rounds of single application treatments, increase the dose to two applications an hour or so apart, letting the first application be fully absorbed. Wait a few days or do this once/week.
* Skin with severe sun damage, such as the back of hands, might need three applications in a day. Do this once and wait two weeks. Three applications to the face will cause minor peeling that can persist two weeks or longer.
* Do not apply 4 applications in a day. That dose has the effect of a medium depth chemical peel, such as with TCA. Going slower is safer and effective.
This mixture is potent and dangerous. Three applications / day for five successive days resulted in tingling and numbness on my face. Fortunately, the nerves were stunned, not killed, and feeling returned to normal in about a week. Neuropathy is a possible side effect of dasatinib.
The improvement to my skin has been remarkable. Small keratoses have disappeared (some larger ones receded but remain), skin roughness improved, hyperpigmented spots receded or disappeared, loose skin on my neck tightened and fine wrinkles are much reduced. Overall, the appearance of skin on my face and neck improved by at least 15 years.
I plan to continue with one application/week for the next couple of months."
