  Can a retinoid formula be made less drying without impairing efficacy?

  Something I’ve been wondering, you see a lot of recommendations for using moisturizer after applying a retinoid (say 0.2% retinol and above or equivalent), but couldn’t you just make a more moisturizing retinoid formula without impairing efficacy?

  Are there moisturizing ingredients that could impair penetration? (e.g. film formers)?

  How would you go about this?
