Skin Boosters: Deep Hydration for Radiant Skin

Skin Boosters are injectable treatments with non-crosslinked hyaluronic acid that hydrate the skin from within, improving its quality, elasticity, and radiance.

What are Skin Boosters and how do they work?

Skin Boosters are aesthetic medicine treatments consisting of microinjections of non-crosslinked hyaluronic acid directly into the skin. Unlike traditional dermal fillers, their main objective is not to add volume, but to improve the hydration and intrinsic quality of the skin. They act as a hydration reservoir, attracting and retaining water in the deep layers of the dermis.

Hyaluronic acid is a substance naturally present in our skin, essential for maintaining its elasticity and turgor. Over time, its production decreases, leading to dehydration and loss of radiance. Skin Boosters replenish this hyaluronic acid, also stimulating the body's own production of collagen and elastin.

Who can benefit from Skin Boosters?

This treatment is suitable for a wide range of people who wish to improve their skin quality. It is particularly beneficial for:

  • People with dehydrated, dull skin or lacking radiance.
  • Those looking to prevent the first signs of aging or soften fine lines.
  • Individuals with sun-damaged skin or uneven texture.
  • Patients who want to improve skin elasticity and firmness on the face, neck, décolletage, and hands.

At Santé Clínica Estética, our doctors evaluate each case to determine if Skin Boosters are the most suitable option for your concerns and aesthetic goals.

Application areas and expected results

Skin Boosters can be applied to various areas where the skin shows signs of dehydration or aging. The most common areas include:

  • Face: for global hydration and improved radiance.
  • Neck and décolletage: to treat thin skin and wrinkles in these areas.
  • Hands: to rejuvenate the skin and improve its appearance.

The results are usually more hydrated, elastic, soft, and radiant skin. The improvement in skin quality is progressive and becomes more evident a few weeks after treatment, as the hyaluronic acid integrates and stimulates skin regeneration. Results vary depending on the patient and the initial condition of their skin.

The treatment process: what to expect?

The Skin Boosters procedure is simple and performed in the clinic. It begins with cleaning the treatment area. Subsequently, a topical anesthetic cream is applied to minimize any discomfort during the injections. Our board-certified doctors use very fine needles to perform multiple microinjections of hyaluronic acid into the superficial or middle dermis.

Each session lasts approximately 30 to 60 minutes, depending on the areas to be treated. After the treatment, small papules or redness may appear at the injection sites, which usually disappear within a few hours or days.

Treatment timeline and maintenance

For optimal results, an initial protocol is recommended, usually consisting of several sessions spaced over time. Subsequently, maintenance sessions can be performed to prolong the effects.

Phase Number of Sessions Recommended Interval Objective
Initial Phase 2-3 sessions 2-4 weeks Deep hydration and improvement of skin quality
Maintenance Phase 1 session Every 4-6 months Prolong results and prevent aging

Results are generally evaluated two weeks after the last initial session, when the hyaluronic acid has fully integrated and the skin has begun its improvement process.

Possible side effects and contraindications

Like any injectable procedure, Skin Boosters can have some mild and temporary side effects. These include redness, swelling, small bruises, or sensitivity in the treated area. These effects usually resolve spontaneously within a few days.

Contraindications include pregnancy and breastfeeding, active infections in the treatment area, autoimmune diseases, known allergy to hyaluronic acid, or bleeding disorders. It is essential to discuss your complete medical history with the doctor during the consultation.

Frequently asked questions

Are Skin Boosters the same as hyaluronic acid fillers?

No, although both use hyaluronic acid, their function is different. Hyaluronic acid fillers are designed to restore volume, fill deep wrinkles, or define contours. Skin Boosters, on the other hand, use non-crosslinked hyaluronic acid to hydrate and improve skin quality, without adding significant volume.

When do results start to show and how long do they last?

The first signs of improvement in skin hydration and radiance can be noticed from the first week, but optimal and longer-lasting results are appreciated a few weeks after completing the initial protocol of 2-3 sessions. The duration of the effects usually ranges from 4 to 6 months, at which point a maintenance session is recommended.

Is there any special care after the treatment?

After the injections, it is recommended to avoid direct sun exposure, saunas, steam baths, and intense exercise for the first 24-48 hours. It is important to keep the skin clean and hydrated and follow your doctor's specific instructions. Cold compresses can be applied to reduce swelling or small bruises.

What is the price of a Skin Boosters session at Santé Clínica Estética?

The price of a Skin Booster session is 250€. During the free consultation, your doctor will inform you about the recommended complete protocol and the estimated total cost.

Can I combine Skin Boosters with other aesthetic treatments?

Yes, Skin Boosters can be combined with other treatments such as neuromodulators, laser, or peels to achieve more comprehensive facial rejuvenation. Your doctor at Santé will design an integrated treatment plan if necessary, always respecting appropriate timings between procedures to ensure your safety and the best results.
