Regenerating the skin from within with collagen stimulators. It improves firmness, hydration and skin quality gradually and lastingly — without changing volume or expression.
In short
Facial biostimulation activates your own collagen to restore firmness gradually and naturally. A 30–45 minute session, minimal downtime and results lasting 12–18 months; the price depends on the product and is set at the assessment. Treatment is performed by Dr. Rubén Bermejo Pérez, a registered aesthetic physician (COMB no. 63226), at Clínica Sagrada Família, Barcelona.
Dr. Bermejo explains why biostimulation doesn't fill: it helps your skin produce collagen and elastin gradually.
Medical judgement
“Biostimulation doesn't add or take away. It activates what the skin already knows how to do — produce collagen — and the result reads as health, not treatment.”Dr. Rubén Bermejo Pérez
How it works · Facial biostimulation
It doesn't fill: it activates your skin.
The cells in the dermis that make collagen and elastin.
The biostimulator signals them to produce more.
The improvement is natural and shows between three and six months.
What it treats
Skin gradually loses firmness and elasticity from the age of 30. Biostimulators activate fibroblasts — the cells that produce collagen and elastin — from within. The result isn't immediate but it lasts: the skin improves its real structure, not just its surface appearance.
Dull skin lacking radiance, with uneven texture, is a common complaint that doesn't respond well to filler or toxin. Biostimulation improves the skin's intrinsic quality — hydration, radiance and texture — gradually and very naturally.
Biostimulation is the ideal complement to fillers and botulinum toxin. While filler restores volume and toxin relaxes expression, the biostimulator improves the quality of the tissue that supports them. Combining them gives a more complete, longer-lasting result.
The skin of the neck, décolletage and hands ages earlier and responds less to other treatments. Biostimulation in these areas improves firmness and hydration very effectively — one of the few non-surgical options with real results there.
The practical side
Everything you need to know before your consultation. No small print.
The stimulated collagen lasts 12 to 18 months. One maintenance session a year is recommended to keep the result.
Including numbing cream beforehand. The usual protocol is 2–3 sessions, 4–6 weeks apart.
Possible redness and small visible bumps for the first few hours. They disappear on their own within 24–48 h. Normal life straight away.
It depends on the type of biostimulator, the areas treated and the number of sessions.

Frequently asked questions
Straight answers about collagen biostimulators. If your question isn't here, write to me.
There isn't a single price. It depends on the type of biostimulator, the areas treated and the number of sessions. The first consultation is free. You can see all fees on the prices page.
Usually 12–18 months. One maintenance session a year is recommended to keep the result.
At Clínica Sagrada Família, C/ Torras i Pujalt 1 (3rd floor), Barcelona. It is performed personally by Dr. Rubén Bermejo Pérez, registered physician no. 63226.
A biostimulator is an injectable that doesn't add volume but activates fibroblasts — the dermal cells that produce collagen and elastin. The best known are calcium hydroxylapatite, poly-L-lactic acid and polynucleotides (PDRN). Each has its own mechanism of action and indication.
The result is gradual — it starts to show 4–8 weeks after the first session and improves over the following 3–6 months. That's part of what makes it natural: collagen doesn't form overnight.
The usual protocol is 2–3 sessions, 4–6 weeks apart, followed by one maintenance session a year. The exact number depends on your skin and the type of biostimulator used.
No. Hyaluronic acid replaces volume immediately — it works as a filler. A biostimulator doesn't add volume; it activates the skin's own collagen production. They complement each other rather than replace each other.
Discomfort is moderate — there are multiple micro-injections across the treated area. We apply numbing cream beforehand for comfort. Most patients tolerate it well. For the first few hours there may be some stinging or tightness.
Yes — that's one of its great strengths. Biostimulation is often combined with hyaluronic acid fillers, botulinum toxin and HIFU. Each works on a different layer of tissue — together they give a more complete result than any one alone.
Minimal. For the first few hours there may be redness and small visible bumps at the injection points — they disappear on their own within 24–48 hours. You can wear make-up and carry on as normal the same day.
