If you're someone using tretinion or planning on starting tretinion treatment on your skin, I made a list of necessary follow up products to get alongside the tretinion
Tretinion dries out the skin, so following it up with a moisturizer will keep the skin hydrated
Advanced Snail 92 All in one Cream
Tretinion and sun is a NO factor, so even if you use tretinion at night, you have to make sure to use a lot of sunscreen the next morning
Reihaku Hatomugi UV Milky Gel SPF 50 250ml
If you're on a low budget you can get this and it will do the job

You'll need a hydrating serum and getting this serum is chef's kiss
Hyaluronic Acid 2% + B5 (with Ceramides)
This can be applied on dark places like your elbows, underarms and knees when you use the tretinion
Glycolic Acid 7% Exfoliating Toner
This sunscreen would be used for your face while the hatomugi sunscreen would be used on the body
