Only used it on the upper half of my face so no shaving impact but I would expect shaving may become a problem if the lower portion of your face has much reaction to the treatment.
Here I am at day 19. 19 was so itchy I needed oxy. By 23 I was almost clear. I had to scrub my face with a wet paper towel before reapplying. But, as a kid, I got sunburned all the time. I used to peel sheets of skin off. I circulated that photo to my nephews and nieces as a cautionary tale about the need for sunscreen. I did keep shaving with an electric razor IIRC.
For those contemplating this you might try the following instead. You use it for 5 days instead. Worked for me. It’s a combination of fluorouracil and vitamin D.
By day 4 I had red splotches which disappeared by day 10. Redness gone by day 14. Much easier than the flourouracil alone.

There’s no downside. If it doesn’t work well enough you can always do the other
I've got an appointment with my dermatologist in a couple weeks and might be interested in this. Were you prescribed this in the US? The clinic link you included is located in Australia.
Thanks, I'll mention it during my appointment if they suggest I should do the fluorouracil treatment.
Worst case I think is it will work partially but not as well as the full burn. But that’s an easy assessment.
