Dermaroller and collagen induction therapy
The concept of collagen induction therapy is simple: stimulate the skin’s own production of collagen, reducing the appearance of wrinkles, and improving the skin’s texture. After applying local anesthesia through a lidocaine cream, a sterile medical reel (known as a Dermaroller) is used that contains about 200 very fine needles, which produce a large number of microscopic channels in the deep dermis. This “controlled wound” stimulates the body to synthesize collagen to repair the skin. The channels also allow better penetration of topical treatment products. Results can last 5-10 years or longer. The use of the derma roller is ideal for the non-surgical and non-ablative treatment of various skin conditions, such as aging (wrinkles, stretch marks), scars (acne, surgery, old wounds), and pigmentation problems. A large number of clinical studies have shown that the use of derma roller in collagen induction therapy is as effective as other more aggressive treatments, such as fractionated lasers, dermabrasion, or chemical peels. Collagen and elastin stimulation has also been shown to be comparable to LPI (Intense Pulsed Light) and Fraxel treatments, helping to increase skin thickness and thus reduce wrinkles, stretch marks, and scars. This can be applied through medical treatments that last several sessions (2 or 5 treatments every 2 months), but they are also suitable and practical to use for personal use at home.

What is it and how it works?
The Derma-roller is a manual device that consists of a handle with a wheel in which several microneedles are inserted. As it slides through the skin, it causes dermo-abrasion, and at the same time, creates channels in the corneal layer that facilitate the entry of active ingredients, in addition to considerably favoring the production of collagen and elastin. How is it possible that a device so simple and accessible to everyone favors the production of collagen and elastin? The reason is the following … When the skin is attacked, it starts to manufacture new skin, and for this, it produces large amounts of collagen and elastin. The interpretation that the skin makes when the Dermaroller is passed is that it is being attacked and defends itself by manufacturing new skin, and to manufacture new skin, it has to produce a lot of collagen and elastin, so the production stimulus is activated to deal with the aggression.
How to use; How is it used?
The roller has to be pressed a little so that the needles not only do their dermo-abrasive work but also open those channels that allow the active principles to pass through. 10 passes through each zone will be made by rolling the roller from left to right (10 times), up and down (10 times), and diagonally (10 times).
Once the derma roller has been passed through all areas of the skin, it is recommended that without sliding the roller but keeping it in specific areas, it is pressed against the skin to make those “micro-holes”.
Very sensitive skin should pass the roller more gently and increase the pressure as possible in subsequent sessions. This technique can be aggressive on very sensitive skin, so the pressure and number of strokes will be adjusted according to each skin. Sometimes it is necessary to use an anesthetic cream, sold in pharmacies.
Depending on the length of the needles, it will be used for one function or another. For example, derma rollers whose needles are 0.25mm to 1mm long are used for the face; If the needles are longer, they are used at the body level to treat stretch marks, spots, localized flaccidity …
The more needles you have, the fewer passes you have to make on the skin and the less aggressive the technique is, as well as faster and more comfortable.
Running the derma-roller over your skin too often will not give you better results. Why not? Think about it, similar to when you cut a finger, it takes time to heal. The small wounds created by the derma roller during skin puncture also take time to heal and build collagen. Even when they are much smaller than a knife cut, you have to allow time for your body to go through the natural process of skin healing.
The renewal of the skin and the new reconstruction of collagen continues for about 40 days after the puncture, this should mainly be taken into account when deciding how often to use a derma roller.
Frequency of use depending on the length of the needle:
0.2-0.25mm derma roller can be used daily or every other day. This size improves the absorption of applied skincare products.
0.5mm derma roller can be used once every 3 weeks.
0.75mm derma roller can be used once every 4 weeks.
1.0mm derma roller can be used once a month (every 5-6 weeks).
1.5mm derma roller can be used once every 6 weeks.
2.0-2.5mm derma roller can be used once every 8 weeks.
