I've had issues like that: Buy hydrolyzed collagen supplements (take 30g per day at start for 1 week) and increase fat intake, simplest is beef tallow (ideally grassfed), eat 2x 5 table spoons of it per day for 5 days at start. And cut all processed sugar and sweets. Replace table sugar and fructose with glucose.
