I started taking Collagen in powder form 9 months ago which improved my skin within a couple of weeks. Friends and family began to notice the visible difference. For convenience, I switched to capsules and found Purolabs Complex just as effective. I'm 70 years old and people just don't believe my age and ask what is my secret? Of course a healthy lifestyle helps. I don't smoke, avoid extreme exposure to sun, no caffeine and eat a high protein and low carbs diet. But the Collagen has definitely improved my skin, hair and nails immensely. Photos taken recently.
