How effective are home care products that you can use instead of visiting a dermatologist?

These days, due to the time and cost constraints, many people are turning to home care products instead of visiting a dermatologist. There are various home care products like serums, sheet masks, and beauty devices, but I'm curious if consistent use can actually improve skin. I'm also concerned about whether focusing on convenient home care products for busy days is sufficient, or whether I should use multiple home care products in stages. I've heard that choosing home care products that are less irritating for sensitive skin is important, but I'd also like to know what to look out for in terms of ingredients and frequency of use. If there's a way to effectively utilize home care products that are right for me and maintain a stable skin condition, I'd like to know more.
