It depends on what you're treating. Both contain Retinol; CeraVe Resurfacing Retinol Serum (Post-Blemish) adds Niacinamide and Licorice Root; Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum adds Peptides.
What's the difference between the CeraVe Resurfacing Retinol Serum (Post-Blemish) and the Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum?

Are the CeraVe Resurfacing Retinol Serum (Post-Blemish) and Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum dupes for each other?
Partly. They share Retinol, but CeraVe Resurfacing Retinol Serum (Post-Blemish)'s Niacinamide and Licorice Root and Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum's Peptides aren't in the other, so they aren't full substitutes.
Can I use the CeraVe Resurfacing Retinol Serum (Post-Blemish) and Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum together?
There's no benefit to using two retinoids at once, and it raises the risk of irritation. Pick one.
