Paula’s Choice Resist 10% Niacinmide Booster •A concentrated niacinamide treatment that addresses enlarged pores, signs of aging and dullness. Purchased from a reputable retailer, Dermstore. See photo added that shows my order number. This was purchased in 2018. Paid retail $35 (after 25% coupons. Retails $49). Product was never used and stored in cool dry place. I forgot I had it, and my skin care needs have changed. Due to the fact that it’s expired, I am selling it at a very reduced price. Efficacy is reduced after expiration dates. But I’ll let you be the judge of that. Thanks for shopping my closet.
