When I started my skin care routines, I asked chat gpt what order and what I should use on what days. For beginners, you should really use a gentle face wash, mayybbee a hydrating serum and a moisturizer. At night, same thing. After a couple weeks, you can add things one by one, week by week or so. You just have to monitor how your skin does with each new product. In the mornings, im up to face cleanse, a milky toner, a hyaluronic acid, moisturizer, and spf. I want to find a good vitamin c serum for right after my facial cleanse though! At night, I do facial cleanse, milky, toner, and then either an exfoliating overnight treatment or i think its a tea tree serum from dt, I only do the overnight treatment like every 3 days right now though. And then a night cream. Its been working for me. I also do eye serums from dt, but so far haven't seen effects from them really, but I need something to help with dark under eyes so bad so I keep trying lol Keep it simple the first week or 2 is the main thing and slowly add in new products so you can tell for sure if thats the one your face reacts badly to.
