The optimal needle length for professional microneedling - benefits and risks of needle lengths from 0.3 mm.

Microneedling has established itself as an extremely effective method in aesthetic medicine to improve skin texture and treat various skin problems. With the XCellarisPro Twist and the medical Dermarollers, high-performance devices are available that have been specially developed for professional applications. This article provides a detailed look at the features and benefits of the Twist and medical Dermarollers, particularly the needle length of up to 2.5 mm and why applications with needle lengths of 0.3 mm or more should only be performed by trained professionals.

The Skin: Our Largest Organ
The skin is the largest organ of the human body and performs a variety of functions. It consists of three main layers:

1. Epidermis: The outermost layer of the skin, which renews itself every 28 days. New skin cells, the keratinocytes, are formed in the basal cell layer and migrate to the skin surface, where they keratinize and form the stratum corneum as horn cells.
2. Dermis: The dermis forms the actual connective tissue of the skin and contains vessels and nerves that are responsible for supplying the skin. It is traversed by a network of collagen and elastic fibers that give the skin stability and flexibility. The hair follicles are also located in this layer of skin.
3. Subcutis: This layer consists of loose connective tissue with embedded fat cells that serve as energy stores and cushions.

This complex structure of the skin, with a thickness ranging from about 0.5 mm on the eyelid to 4 mm on the sole of the foot, makes it necessary for microneedling devices to work precisely and effectively to achieve optimal results without damaging the skin.

The XCellarisPro Twist and Medical Dermarollers: Technical Superiority
The XCellarisPro Twist is the most powerful device on the market and offers a continuously adjustable needle length from 0.3 mm to 2.5 mm. This flexibility allows the treatment depth to be precisely adjusted to the patient's needs and the skin region to be treated. The needle length is adjustable on the ergonomically shaped handpiece, allowing for comfortable and efficient use.

The medical Dermarollers are available in needle lengths from 0.5 mm to 2.5 mm and have 4, 9, or 18 needles per row. These devices also offer flexibility and precision. The different widths allow for individual adaptation of the treatment depending on the size of the skin area to be treated.

The needle length of up to 2.5 mm is particularly important as it penetrates deep enough to reach both the epidermis and the dermis. This is crucial for stimulating collagen and elastin production as well as cell renewal. These processes are essential for improving skin structure and achieving long-term results.

Why Needle Lengths of 0.3 mm or More Should Only Be Used by Professionals
Once the needle length exceeds 0.3 mm, the needles can penetrate the dermis, where blood vessels and nerves are located. Improper handling of these needle lengths can lead to serious complications, including:

• Bleeding and Hematomas: Injuring blood vessels can cause bleeding and hematomas, which are not only uncomfortable but also increase the risk of infections.
• Nerve Damage: The dermis contains many nerve endings. Inexperienced users can damage these nerves, leading to pain, numbness, or other neurological symptoms.
• Infections: Penetrating deeper layers of skin increases the risk of infections. Professionals have the necessary knowledge and equipment to ensure sterile conditions and avoid complications.
• Uneven Results: Improper use can lead to uneven results, which can worsen the skin's appearance rather than improve it.

Multiple Applications of the XCellarisPro Twist and Medical Dermarollers
Thanks to their precise technology and flexible needle length adjustment, the XCellarisPro Twist and medical Dermarollers are versatile. Here are some of the main applications:

• Anti-Aging: Stimulating collagen and elastin production reduces fine lines and wrinkles, and the skin regains its youthful firmness and elasticity.
• Stretch Marks: Professional microneedling can help reduce the visibility of stretch marks by promoting skin regeneration.
• Dry Skin: Microneedling can improve the absorption of moisturizers and serums, leading to better skin hydration.
• Hair Loss: Scalp treatment can promote blood circulation and stimulate hair growth.
• Hyperpigmentation: Stimulating skin cell renewal can help reduce dark spots and uneven skin tones.
• Acne Scars: The XCellarisPro Twist and medical dermarollers can improve the appearance of acne scars by stimulating the regeneration of scar tissue, smoothing the skin surface.

Conclusion: Microneedling at the Highest Level with the XCellarisPro Twist and Medical Dermarollers
The XCellarisPro Twist and medical Dermarollers are the most powerful microneedling devices on the market. With adjustable needle lengths of up to 2.5 mm, they offer the necessary flexibility and precision to effectively treat a variety of skin problems. Their ability to penetrate deep into the skin layers while stimulating collagen and elastin production as well as cell renewal makes them indispensable tools in professional skincare. Therefore, it is crucial that applications with needle lengths of 0.3 mm or more are only performed by trained professionals to achieve optimal results and avoid complications.
