Hero Cosmetics Retinol Replacement

My skin hates basically all the ingredients I need to use. I’m super sensitive and dry, and am dealing with closed comedones again that will not go away. I wanted to try retinol again. Hero’s gentle one is the only one that didn’t make my skin start burning after a single use but it appears to have been discontinued. Is there anything comparable in terms of gentleness and consistency (it felt satisfyingly thick but not heavy).
