Micro-needling is the process of creating many microscopic punctures in your skin. You may reasonably ask yourself: Why would anyone want to do that? The reason is simple: when your skin is punctured, it responds by increasing collagen production, improving hair growth, and reducing the appearance of scars.
The challenge, and the reason this should be done by a trained dermatologist rather than at home, is ensuring the punctures do not go too deep or trigger any other health concerns. Your skin is the protective barrier between your immune system and the world; microneedling should not be done without adequate training and precaution.
