She further argues that the body does not instinctively direct consumed collagen towards the skin, given that there are more than 30 distinct types of collagen distributed throughout the body. Another point she raises is that individuals purchasing costly supplements are frequently already maintaining a healthy lifestyle, including nutritious eating habits and using quality skincare products, which makes it challenging to determine the supplements' specific impact.
