FEA-guided co-design of bubble microneedles: controlled tip separation for rapid transdermal and sublingual delivery

A user shared a video suggesting that 0.5mm microneedles are most effective for hair growth. Other users mentioned different microneedle lengths and advised consulting a dermatologist for personalized treatment.

The conversation discusses the steps for microneedling, specifically differentiating between medical needling (0.5-1.5mm) and cosmetic needling (0.3mm). It emphasizes the importance of cleaning and disinfecting before microneedling, regardless of needle length.

The conversation is about starting microneedling for hair growth, with questions on needle sizes, session frequency, and reliable purchasing options. The user seeks clarity on FDA regulations and prefers to avoid certain online retailers.

Microneedling can promote hair growth, but there is uncertainty about the best practices, including needle length, device, and session frequency. Users discuss using needle lengths between 0.5mm and 1.5mm, with some experiencing pinpoint bleeding, and emphasize the need for more reliable resources and guidelines.

Microneedling can cause infections if not done carefully; users suggest using alcohol swabs and reducing needle depth to avoid issues. Proper sanitation and gentle pressure are key to preventing bleeding and infection.

The conversation is about using a Dr. Pen for microneedling on a widow's peak, with advice to use a depth of 1.25mm and hold it in place for 10 seconds. The user is also using minoxidil.
