I’m almost 54 yrs old and have been overweight my ENTIRE life - with lots of fluctuations . I lost 100+ lbs on IP in my first year and I took collagen the entire time. I am saggy, crepey and flabby. Every area of my body. Big time. I went to my dermatologist AND GP and both said that the collagen is great for joints and ligaments but due to the size of the skin organ collagen barely has an effect. Soooo, I waited a full year to see what happened with my skin, as I was advised that it takes a year for the skin to adjust when you rapidly lose weight. Verdict: I have had minimal change. I’ve resigned myself to the fact at my age and years of yo yo diets I’ve blown out my skin. My option would have to be skin removal. which I have mixed feelings about, but I’m giving myself this next year to lose a bit more weight and focus on muscle tone, and then I’ll revisit the idea of surgery. With all that said, I’ll take being a saggy mess over being obese any day!
