Does anyone have any experience or knowledge on which active ingredients work best for different skin types?

I have extremely dry skin (grandparent had ichthyosis) and I’m wondering if some might work better for me based on that. I used a lactic acid moisturizer for years which helped but only to a point - I’m now trying salicylic acid + urea, but also wondering about glycolic acid. Also wondering whether I should focus more on improving the skin barrier or on exfoliation due to the extreme dryness… it’s a mine field!

Any insights would be welcome
