  • It can also be used to treat hyperpigmentation, alopecia, acne, cellulitis and scarring, amongst others.
  • Micro-needling can cause some discomfort, but it does not require anaesthesia and after 2-3 hours you can resume your normal activities.
  • The micro-needling device can be calibrated to a specific depth to adapt the treatment to the specific zone of application.

Micro-needling. Stimulating collagen and treating imperfections.

It can be used to treat:



Sun-induced ageing

Acne scars

Changes to skin pigmentation


Stimulating collagen





Open pores

It is not painful, but causes a reddening of the skin which lasts for 2-3 hours, after which the patient can return to their normal daily activities.

What is micro-needling? What is Nanopore? How does it work?

Micro-needling is a procedure in which the skin is pricked at various points in order to stimulate collagen production.

Nanopore is an electronic cosmetic device that uses microneedles to penetrate the skin of the face at different depths depending on the zone of application. This leads to increased collagen production and increased absorption of skin products.

During the mico-needling session, the microneedles are applied at a controlled speed and depth opening up microscopic channels in the epidermis. It is through these channels that the active ingredients are absorbed, depending on the condition being treated, and new collagen is then produced.

What is the objective of this technique?

The channels created in the micro-needling sessions help to stimulate collagen production at the dermis level. Products can also be injected into the skin through the needles such as hyaluronic acid, vitamins, growth factors and other active ingredients that help to treat skin ageing and other imperfections and to improve skin quality.

What can it be used to treat?

Collagen inducing therapy is aimed at improving skin imperfections. It is suitable for:

  • Fine lines
  • Sun-induced skin ageing
  • Acne
  • Changes in skin pigmentation
  • Sagging
  • Burns
  • Alopecia
  • Cellulitis
  • Stretchmarks
  • Scars
  • Improved absorption of active ingredients
  • Open pores

Is anaesthesia necessary?

Micro-needling is an outpatient procedure which does not require anaesthesia. The microneedles can cause some discomfort and cause skin reddening, but this disappears after 2-3 hours. The patient is then free to resume their normal routine.

What are the advantages of this technique? Who is it aimed at?

One of the advantages of micro-needling is that as well as its collagen inducing effect, it also enables us to inject active ingredients into the skin through the microneedles, such as growth factors or hyaluronic acid which will help to improve the cosmetic results.

As one of the aims of micro-needling is skin rejuvenation, it is mostly aimed at those over 25. The treatment can, however, also be used by patients of any age to improve skin pigmentation, acne scars and other kinds of scarring.

What effect does it have on the skin? Can there be side effects?

During the micro-needling procedure a series of incisions are made across the whole face and this will cause inflammation. The result is a reddening of the skin which lasts for 2-3 hours and then completely disappears. The procedure is normally painless and the patient can resume their normal activities when the reddening has subsided.

Why carry out the procedure at ICR?

The procedure will be carried out by ICR ophthalmologists who are specialists in oculoplasty. Thanks to their expertise and knowledge of the whole area being treated, none of the surrounding structures will be put at risk and quality, specialist medical care is guaranteed.
