My skin became so smooth, I feel more energy and sleep better, easy wake up in the morning. Perfect antioxidant. It is a bit high price, but the value is unprecedented! I will buy more now. This supplement can be taken continuously. The amount of 100 mg is optimal, but you may take more! I trust this trade mark and tried many other supplements of this brand. All good. ***Pine bark extract or Pycnogenol provides many benefits to the skin, including reducing the visible signs of aging. Not only does it enhance the skin's ability to produce more hyaluronic acid to help maintain hydration, but more importantly, it also helps with collagen production*** Put your thumb up if useful. Be healthy!
