i keep hearing this on tiktok from dermatologists and others and have to cosign as a lazy person who does not do much for her skin (mine is oily for reference). tbh it is in amazing shape and i admittedly do very little. in the morning i wash (avene cleanance), moisturize (avene hydrance - light + the laneige lip sleep mask but i use it when i wake up as well), and apply spf (elta md). at night i consider myself accomplished if i do anything at all tbh. i often sleep in my makeup from the day. if i do anything, i will just remove my makeup (lancome), tone (cosrx but likely switching to laneige soon), and moisturize (laneige water bank cream and lip sleep mask). something important that i learned on reddit last year is to always moisturize while your skin is wet. i am not rly particular about the specifics of this so if my face is still wet after washing i will just use that, otherwise i apply an essence (i use the one from philosophy). anyway according to me, all u have to really do every day is cleanse, moisturize, and protect, but im truly not an authority on this so if u have a dermatologist or similar source listen to them!!
