Hi fellow LMT's! I hold a dual license in massage therapy and esthetics for 12 years. Have you heard of BioCell Collagen?? I was first intrigued by this company because I could sell it in the spa I work and make 30-40% commission by having my own account. And we all know working in a spa, we typically only get 10% commission on retail. 
Even better than the profit is the benefits and results my clients are seeing from taking this life blend. Hyaluronic acid, chondroitin and biocell collagen in a liquid form. This is the first of its kind, from the makers of supplements for the vitamin shoppe, gnc, and other stores.
My clients take 2oz in the morning and 2oz in the evening so that they are replenishing what the enzymes in our body are constantly using. I am seeing clients with rheumatoid arthritis getting off painful injections, athletes recovering much quicker from injury, low back pain diminishing. My skin care clients are reaping the benefits of longer lasting botox results, those who have never used injectibles aren't even considering it now that they are taking liquid collagen, my acne patients are seeing great results with keeping skin hydrated with Hyaluronic Acid since they are using drying ingredients topically.
This product is multi-patented, medically documented and has been shown on Fox News and good morning America.
I take the supplement as a preventative since I know doing massage therapy is manual labor and hard on our joints, even with the best posture and techniques and also to keep my skin literally glowing from the inside out.
I would be delighted to guide you on how to effectively market this to your clients.
