I used to work for a dermatology practice with many MDs and DOs for 7 years. In regards to collagen, your body naturally produces it, but due to age and other factors, the production decreases. They would say that the primary way to stimulate your body to produce more is through "skin injury." In the derm world, it would be chemical peels, IPL, microdermabrasion, or microneedling. Obviously, not all of us would want to do that. First of all, it's cosmetic, so insurance won't cover it. Secondly, it's expensive. Thirdly, the downtime can be long. And lastly, depending on your skin, there's always the risk of scarring. So, the next option for collagen stimulation is to ingestion. I just received this product and I'm looking forward to see results. I'm aware of its multi-benefits, but I'm really after the skin and joint pains. I like the packaging, the size of the capsule, the price, and the expedited delivery.
