Some clinics might try to upsell you on expensive aftercare products, but honestly you don't need the most expensive options. You'll definitely need a good moisturizer and sunscreen, which you should be using anyway. Some clinics include basic aftercare instructions and recommendations, but be cautious about feeling obligated to buy their branded products. You can often use affordable drugstore options that work just as well. Ask upfront what the treatment includes and what products are optional versus necessary.
