The abrasion of the skin is carried out mechanically by means of a grinding wheel or by laser. The skin is sometimes damaged by the sun or simply by wrinkling (wrinkles of expression), against which abrasion can work miracles. It is a surgical intervention which consists in “using” the skin and more precisely the epidermis (upper layer of the dermis). This is performed under local or regional anesthesia. Dermabrasion does not require hospitalization, it is usually done at the dermatologist’s office in town.
Dermabrasion It uses small abrasive wheels rotating from 20,000 to 40,000 revolutions per minute depending on the type of motor and which can be varied using a pedal called a rheostat pedal (a kind of potentiometer). On these motors are attached abrasive elements (metal brush, diamond cutter, grinding wheel) whose diameter and grain (surface allowing corrosion) are of different sizes. The attack on the skin is done from several angles. The therapist (surgeon, doctor, dermatologist) planes the epidermis and the upper layers of the dermis
Dermabrasion should not be confused with peeling which is also a skin wear technique, but more superficial. It is not covered by social security and the aesthetic results are not always excellent.
This technique is gradually being replaced by laser dermabrasion. Currently dermabrasion uses the skin abrasion system, more modern equipment including a compressor that projects alumina crystals like a Karcher. This device also incorporates a suction pump which makes it possible to recover skin debris.
Anti-wrinkle micro-dermabrasion in institutes and centers
The objective of microdermabrasion is to smooth the epidermis and improve the radiance and texture of facial skin.
Microdermabrasion is performed using a device that projects microcrystals onto the skin at high speed, and re-aspirates the skin cell debris using the same probe. It is done on the face, hands, décolleté, but also the body to reduce stretch marks. Microdermabrasion is a technique practiced for fifteen years by dermatologists and beauticians to renew the upper layers of the epidermis. Recommended in cases of fine lines and wrinkles.
It is a sort of superficial physical “peeling” a priori but which can be deeper according to the wishes of the practitioner or the patient. It consists, like “sanding” for stone buildings, in projecting crystals (generally corundum) onto the skin, in order to remove the superficial layer of epidermis.
The repetition of passages of the handpiece, and the increase in the vacuum in the pump allow a more or less intense action. This forces the epidermis to regenerate, and as with peels, has a “radiance boost” effect. The technique of microdermabrasion in the aesthetic field is also called micro-peeling and consists of walking over the surface of the body to treat a pen that causes a sweep of highly purified corundum micro crystals. Particles and skin cell fragments are sucked back into a bottle for disposal. Depending on the projection power, the client’s sensitivity and the area to be treated, the beautician will adjust the projection power of the micro corundum crystals according to the area to be treated.
Procedure of a micro-dermabrasion Make-up removal and cleansing of the skin, then gradual use of the handpiece (sandblasting) in small areas until the entire face is treated if necessary. The session lasts 20 to 30 minutes. It is advisable to do a series of at least 4 sessions, one session per week or every 15 days.
Results to expect: “Blowout” effect. After the session, the face is a little red, depending on the depth reached by the practitioner. Sometimes crusts can appear on the places where he insisted more. The days that follow, the complexion is radiant. Some patients do it 2 days before an important event to look good. With the repetition of the sessions, there is an effect on fine lines, the lightening of the complexion, and spots.
It is very important that you choose a competent and experienced professional who has completed one or more specific training courses in microdermabrasion. For a visible effect, 6 to 8 sessions on average are necessary. Count on average 80 to 100 € per session.

Restore NAD+ to Supercharge Your Cells and Rejuvenate Your Entire Body with ALIVE BY SCIENCE – Bioavailable NAD+ Boosters. ALIVE BY SCIENCE consults with a wide range of research and clinical doctors to grasp the newest research and combine it with input from tens of thousands of consumers on their forum and Facebook group as the industry leader and largest maker of NAD+ products.
Tru Niagen is nicotinamide riboside , a unique type of vitamin B3. Niagen is a NAD+ precursor that acts as a building block for the production of NAD+ in your body. This is significant because NAD+ is an essential coenzyme for cellular health; yet, NAD+ levels fall with aging and other physiological stressors including poor food, alcohol, lack of sleep, or too little or too much activity. Tru Niagen has been clinically demonstrated to aid in the increase of NAD+ in the body. Niagen is the first and only patented and FDA-approved nicotinamide riboside product.
