Help with Tretinoin routine

You can use it day and night. I'm using tretinoin 0,05% every night now. I prefer to use it direct on my skin but some nights that I'm feeling I need more hydration or I'm a little bit sensitive I would definitely use a hydrating toner and serum before I apply my tret.

You can apply your essences and toners both morning and night, whichever you prefer. Definitely apply the pyunkang yul toner first, then the snail mucin (thinnest product to thickest product) Tretinoin in the evening only. I apply moisturizer, then my tretinoin, and then usually a sleeping mask after to "sandwich" my tretinoin with moisturizer. It greatly reduces your chances of getting irritated or becoming red and flakey and it doesnt change the efficacy. These are my go to moisturizers and sleeping masks for tretinoin nights. Make sure you are using SPF daily....especially while using tretinoin.

You can use the Essence Toner and Snail Essence both day and night, and before your tretinoin. ☺️

I use a gentle retinol (not tret) and I use my hydrating products whenever it’s not a retinoid night. AM - cleanser - toner - essence - acne cream - sunscreen PM (with retinoid) - BHA cleanser - retinoid on dry skin - moisturizer PM (with benzoyl peroxide) - 5% BP, short contact spot treatment - BHA cleanser - toner - essence - moisturizer

I would use them both morning and evening. In the evening use them before tret.
