Microneedling (Dermaroller)

Microneedling — also known as collagen induction therapy — works by using a cluster of fine-gauge needles (typically 0.5–2.5 mm in length depending on the target depth) to penetrate the epidermis and reach specified depths in the dermis. At each point of penetration a micro-wound is created; the body's platelet and growth-factor response is activated, triggering a cascade of collagen type I, III and VII synthesis and glycosaminoglycan production. Unlike…

At DermaEsthetic MUDr. Hana Šulcová selects the needle length based on the depth of the concern being treated: shorter needles (0.5–1 mm) for superficial pigmentation and general texture, medium lengths (1–1.5 mm) for fine wrinkles and rosacea, and deeper settings (1.5–2.5 mm) for acne scars and stretch marks. A medical-grade topical anaesthetic is applied thirty minutes before treatment to minimise discomfort during the deeper passes. Single-use, sterile…

During the session the microneedle device is moved across the skin in multiple directions to ensure even coverage; the procedure takes twenty to thirty minutes for a full face. Immediately after, the skin is red and slightly swollen — similar in appearance to a moderate sunburn — and may have pin-point micro-bleeding in areas treated at deeper settings. This resolves within 24–48 hours. Over the following three to four weeks the collagen response…
