When it comes to supplements and skincare products, the quality of the ingredients, the manufacturing process, and the purity of the product can all have a significant impact on its effectiveness. It is very important to look for products that have been independently tested for purity and potency by organizations such as USP, NSF, or ConsumerLab as it will give you some sense of confidence in their products. Concierge Choice supplements have been sourced from very reputable nutraceutical companies and our skincare products are produced in a FDA approved facility that supplies most of high end plastic surgeons and dermatology clinics.
