Skin rehydration


Rehydration with intradermal injections is a very new technique. It involves infiltrating the skin with hyaluronic acid to help prevent aging, thus delaying the formation of wrinkles and restoring the skin´s hydration and elasticity. Hyaluronic acid is present in a healthy dermis to maintain the skin´s elasticity and hydration. Over time its concentration in the dermis decreases. This treatment is carried out when skin most needs hydration, such as after prolonged exposure to sun, wind or rain, or after practicing outdoor sports like skiing or boating. It is also highly recommended for smokers or those who work indoors.

Hyaluronic acid attracts large quantities of water, like a molecular sponge. It also stimulates the formation of collagen and elastin and acts as a powerful antioxidant by blocking free radicals. It is a very safe treatment and its effects are evident from the very first session.

Treatment usually consists of between two and four sessions depending on the state of the skin, each session separated by a two- to three-week period. Maintenance sessions can then be scheduled every three months.

Before the hydration treatment can be carried out the skin must undergo a deep cleaning and degreasing routine. An anaesthetic cream is then applied to reduce the surface sensitivity of the treatment zone. The intradermal microinfiltration process (infiltration of the skin using very fine needles) with hyaluronic acid can then begin in the treatment areas: face, neck and upper chest.

Treatment is finished off with a sterile cryo mask, which gives comfort and freshness to the skin and prevents the formation of any redness or bruising.

Treatment lasts for about 20 minutes and you can resume normal activity as soon as the session is over.


Hospitalisation is not required


This treatment is relatively painless, requiring only a local anaesthetic cream or ice to be applied to the treatment area before the microinfiltration session begins.


Generally, no special care is required before rehydration treatment other than the prescription of preventive treatment for patients who are very prone to bruising.


Patients are advised to wait 24 hours before applying make-up, bathing, taking a sauna, waxing or shaving to give the micro holes created during the infiltration process time to close. A protective layer and a fotoprotector are, however, applied as soon as the session is over. After the initial 24-hour period patients are recommended to use creams that facilitate hyaluronic acid distribution.


Rehydration with this type of intradermal injection is contraindicated for people with an allergy to hyaluronic acid and/or who are taking oral anticoagulants. 

We recommend that these people do not take aspirin or anticoagulants or ingest alcohol for 48 hours prior to the treatment. As the needles are very fine, the application of make-up will be enough to conceal the small bruises that can appear, although these are very rare, and make them practically invisible.

The number of treatments varies according to the condition of the skin, but we usually carry out two to four courses of treatment, each separated by two or three weeks, and a follow-up treatment for maintenance every three months.

We advise that you wait around 24 hours before applying make-up, taking a bath or sauna, waxing or shaving to help the tiny holes left by the injections to close. After 24 hours, we recommend you use creams that enable a good distribution of hyaluronic acid.

Yes. What’s more, the rehydration treatment can be beneficial in this case, as it gives the skin a better level of hydration. In addition, this technique can be combined with many other treatments, such as peels, IPL, fillers or face lifts.

Expert opinion

Dra. Marta Grau

Dra. Marta Grau

Hyaluronic acid as a moisturizing treatment of the skin has very good results. It is carried out in consultation and allows going back to daily normal activities at the end of it. It provides brightness and hydration to the face, and has an immediate effect after application, showing a more nourished and radiant face.

Infiltration of hyaluronic acid into the face on a superficial level will provide hydration to our skin and stimulate the formation of collagen and elastin, which results in a brighter and elastic skin with a younger appearance. It is a preventive treatment in young skin and a real treatment for more mature skin.
