Yes. Right now, we only have an auto-refill plan with an option to cancel anytime. We offer an auto-refill plan because dermatologists really encourage consistent use to prevent “retinization.” Retinization is the period of time in which your skin needs to adjust to retinoids, which usually lasts 4 weeks. When you stop using retinoids for more than that time period, you’d have to start all over, and your skin would have to re-adjust to the product. Your first-time trial bottle is a 2-month supply, and subsequent refills are a 3-month supply.
