Bigatti uses a process called cold-extraction and nano technology to isolate active ingredients that can penetrate and repair the middle layer, while protecting the third, youthful layer. What are peptides? Peptides are a growing trend in anti-aging skin care. They help you produce collagen and elastin that help plump the skin and give it elasticity. Z.
