The 0.75 mm dermaroller for mesotherapy with 540 steel needles is a powerful microneedling roller for intensive skin stimulation and visible skin rejuvenation. The combination of a 0.75 mm needle length and the very high needle density of 540 ultra-fine steel microneedles creates a smooth, controlled treatment focused on firming, improving skin texture, and activating natural collagen and elastin production.
The Prohaar dermo-roller was developed for microneedle mesotherapy and is often chosen as an alternative to more intensive treatments such as laser therapy, plastic surgery, and deep chemical peels. The roller is equipped with steel microneedles (0.25 mm to 2.0 mm) that can create up to 250,000 microperforations in the skin in just a few minutes. These microperforations form microscopic channels, also called microdamages, which activate the skin's natural healing process.
Through controlled stimulation in the epidermis and deeper, fibroblasts are activated to produce collagen and elastin . This supports skin firming, contour refinement, and improved elasticity. Microneedling also significantly increases the absorption of active ingredients: while normally only 0.03% to 3% of active ingredients reach the skin, this can increase by up to 3000% after using a dermaroller.
Needle lengths and applications:
0.25 mm – Gentle exfoliation of the epidermis, stimulation of microcirculation and improvement of skin tone.
0.30 mm – Exfoliation of the epidermis, stimulation of microcirculation, formation of microchannels and evening out of the skin tone.
0.50 mm – Microchannel formation with slight micro-damage to the epidermis and more pronounced skin renewal.
Needle lengths from 0.25 mm to 0.50 mm may be suitable for home use when used correctly and with strict adherence to safety and hygiene guidelines.
0.75 mm – Exfoliates the epidermis, stimulates microcirculation, and creates microchannels. Provides controlled stimulation that activates fibroblasts to produce collagen and elastin . Ideal for those seeking a significant improvement in firmness , elasticity , and skin texture .
1.00 mm – Deeper stimulation with a firming effect and support of blood vessel walls, including addressing discoloration.
1.5 mm – Deep microneedling for intensive regeneration on multiple levels, often chosen for scars or stretch marks.
2.0 mm – Very deep professional stimulation with maximum skin regeneration.
Why 540 steel needles at 0.75 mm? The high needle density ensures an extremely even distribution of micro-perforations. This means the skin is stimulated more consistently, resulting in more even results and better absorption of active ingredients. Combined with 0.75 mm, this provides a powerful, professional treatment that goes beyond pure "glow" and focuses on firmness , refinement , and regeneration .

Who is this dermaroller suitable for?

- Suitable for thin skin and all parts of the face and body.
- The treatment is natural and safe when used correctly and with strict hygiene.
- No lasting side effects when performed correctly
Good to know: every micro-damage activates the skin's self-renewal processes. With age, this process slows down, which you'll notice as slower recovery. Systematic microneedling is an effective way to support regeneration and visibly improve skin density. Skin often feels firmer within 24 hours, while a course of multiple sessions provides longer-lasting results.
Hygiene and safety: Each derma roller must be sterile and sealed before use, so the client can see that the product has not been used previously. After each treatment, the roller must be cleaned under running water and professionally disinfected. Disinfection should also take place before the procedure, for example, with a suitable disinfectant. The treatment can be performed with saline solution.
Treatment advice: For 0.75 mm, anesthesia may be advisable, depending on the sensitivity and treatment area. Be aware of possible pinpoint bleeding and small scabs. Always follow the protocol, with a strict disinfection and aftercare routine.
Please note: For hygiene reasons, this product cannot be returned if the sealed packaging has been opened after delivery.

0.75 mm is generally recommended for professional or highly experienced users. For home use, 0.25–0.50 mm is usually chosen, provided all safety regulations are strictly adhered to.
When will you see results?
Many users experience firmer skin within 24 hours; with a course of treatments, results continue to build over the following weeks.
What is 0.75mm most commonly used for?
For skin firming, improvement of elasticity and structure, and more intensive stimulation of collagen and elastin.
