I have good genetics on my part (my mom has still great skin and she's 85) but I felt like during the last year I was depleted like suddenly and I felt like maybe that was a reflection on my inside too. So I started taking more and more actions. Never tried retinoids, tbh Summary: During the last 2 months I have used: - Profey redlight lamp on Amazon (but there are better options!) - shwally Methylene blue serum (the one with the ghk-cu peptide) - I cook gelatinous broths almost everyday (oxtail, shanks, ossobuco, bones...) - glycine supplement every night I also do other things, but some I was already doing before (magnesium bisglycinate , VIT d & K2, blue light blocker and taking sun in the morning, tallow cream only on my skin) and others that I am still testing and are more personalized (like progest-E, dessicated thyroid supplements & colostrumt)
