Rosacea and retinol

from what i had read, dehydration can accelerate skin aging and makes your lines to be more apparent. So, before venturing into retinol, you should make sure your skin is hydrated by incorporating lots of water-based products. since you have no major skin problems and has rosacea, you might wanna take retinol very carefully since it can cause purging, breakout or even make your rosacea worse. you should start with the lowest retinol percentage, and start building your skin tolerance by using it once a week, before slowly increasing your usage. And you could use sandwich method ( moisturizer - retinol - moisturizer ) to combat the side effects. Also, you should reapply your sunscreen, and try to avoid chemical exfoliation when using retinol in one routine.
