Skin booster
A skin booster is fluid hyaluronic acid, injected in small drops into the dermis. It adds no volume. It holds water where the skin no longer can, and the skin turns softer, more elastic, with more light.

You see it after two to three weeks: the skin catches light differently, fine dehydration lines soften, make-up sits better. The effect builds over 2 to 3 sessions, 4 weeks apart.
At Cosmo Clinic the skin booster is where we start when the problem is skin quality rather than the shape of the face. Face, neck, décolletage or the back of the hands. The assessment consultation is free, and it is where we decide with you whether it makes sense, and where.
What changes with a skin booster
Fluid hyaluronic acid injected in small drops into the dermis. It adds no volume and changes no contour. It holds water where the skin no longer can, and the skin turns softer, more elastic, with more light.
Is it for you?
Dry, dull or tired skin, with fine lines that do not call for filler. Face, neck, décolletage and the back of the hands.
What happens in the session
Numbing cream for 20 minutes, then many small, shallow injections of the 3 ml across the area. Most people describe mild discomfort rather than pain. Thirty minutes.
What you'll see, and when
After two to three weeks: the skin catches light differently, fine dehydration lines soften, make-up sits better. The effect builds over 2 to 3 sessions, 4 weeks apart, and lasts 6 to 9 months after the course.
After the treatment
Small bumps at the injection points for 24 to 48 hours, sometimes a bruise that clears within a week. No make-up for 12 hours, no sauna or direct sun for 48.
Why it looks natural
The booster adds no volume and changes no contour, so there is no shape to get wrong. Fluid hyaluronic acid in small drops holds water where the skin no longer can; what shows is skin that catches light differently and make-up that sits better. The change arrives over two to three weeks, at the pace of skin.
Honest answers
Will it show? Small bumps at the injection points for 24 to 48 hours, sometimes a bruise. The skin change comes after two to three weeks.
Does it hurt? Numbing cream for 20 minutes first. Most people describe mild discomfort rather than pain.
What if I don't like it? Because it is hyaluronic acid, it dissolves with hyaluronidase (€150), though with no volume added there is rarely anything to undo, and the effect fades on its own over 6 to 9 months.
How we do it at Cosmo Clinic

Frequently asked questions
Short answers to the questions we hear every day. Everything else belongs in the consultation.
Who is a skin booster for?
Dry, dull or tired skin, with fine lines that do not call for filler. It works at any age; from 30 is when people ask for it most. At the consultation we tell you whether it is the right answer or the problem is something else.
How is it different from filler?
Filler gives volume and shape. A skin booster gives neither: it hydrates the dermis and improves skin quality. The two can be combined, in separate sessions.
How many sessions do I need?
Two to three to start, 4 weeks apart. Then one maintenance session every 6 to 9 months, depending on how the skin responds.
Where can it be used?
Face, neck, décolletage and the back of the hands. These are the areas that lose water fastest and where the result shows most.
Does it hurt?
Many small, shallow injections. We apply numbing cream 20 minutes before. Most people describe mild discomfort that passes quickly.
How long does it last?
Between 6 and 9 months after the initial course. It depends on your skin, the sun and smoking. A maintenance session extends it.
Will it show?
Small bumps at the injection points for 24 to 48 hours, and sometimes a bruise that clears within a week. No make-up for the first 12 hours, no sauna or direct sun for the first 48.
How much does it cost?
€550 per 3 ml session. Priced per treatment; the number of sessions is decided at the assessment consultation, which is free.
