    TLDR Biopolymers are increasingly used in cosmetics for their non-toxicity and skin benefits, with future biotech advancements likely to expand their applications.
    The document discusses the use of biopolymers in cosmetics, including proteins like collagen, elastin, silk, and keratin, and polysaccharides like Chitosan, Hyaluronic Acid, Sodium Alginate, Starch, Xanthan Gum, and Carrageenan. Biopolymers are non-toxic, biocompatible, and biodegradable, making them ideal for cosmetic formulations. They are used as emulsifiers, conditioners, and more, with specific benefits such as skin hydration, anti-ageing effects, and promoting extracellular matrix remodelling. For instance, collagen can penetrate the skin, retain water, and stimulate the production of new collagen, elastin, and hyaluronic acid. Keratin has been reported to enhance hair growth. Each biopolymer has its own set of advantages, disadvantages, and safety considerations. Future advancements in biotechnology are expected to lead to new applications for biopolymers in cosmetics.

      community microneedle, any long term users damage?

      in Microneedling  35 upvotes 6 months ago
      Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.

      community How do exosome injections for Hair Growth work?

      in Is this regrowth?  1 upvotes 1 year ago
      Exosome injections stimulate hair growth by using exosomes' healing potential to awaken dormant hair follicles and promote new hair cell creation. The procedure increases scalp blood circulation, encourages collagen and elastin formation, and regenerates hair follicles, improving hair thickness and quality.
