They launched a new serum from this line that is targeted for acne I think, so maybe it's an option Routine Help. I recently started using effaclar due to help with hyperpigmentation, but I'm unsure if I can use this with a retinoid. I also want to use benzoyl peroxide for spots but not sure if this can also be used with these two. Other than that I use the ordinary moisturiser, and la Roche Possay spf 50 in the mornings.
