Is keeping a treatment log to see skin changes really helpful?

Because my skin condition seems to change from day to day, it's often difficult to feel the effects of skin care. That's why I've been thinking about the importance of skin care records lately. Keeping a record of what products I used, my skin condition, and seasonal changes can help improve my skin. I'm curious to see how I can observe the changes more objectively. I'd also like to know whether simply taking photos is better, or whether a care log that includes product use and lifestyle habits is more effective. Could you elaborate on whether consistent care logs actually help improve skin, and if there's a method for maintaining them without burden, please explain in detail.
