Firming and smoothing skin without surgery: innovative solutions
19th November 2025
Skin laxity on the face and neck no longer necessarily requires surgery. Today, several technologies can redensify, smooth, and tighten skin by stimulating its own collagen, without surgery or downtime. Some rely on energy (radiofrequency, ultrasound), others on injectable inductors or thread lifts. All these approaches, initially designed for the face, are also used on the body—arms, stomach, thighs, or buttocks—with increasingly convincing results.
Firming and smoothing skin without surgery: innovative solutions
Who is the game for?
Slight to moderate sagging of the face, neck or décolleté; perfect for prevention/maintenance from age 30–35, for skin that lacks “bouncy”.
How's the treatment going ?
A multipolar applicator delivers controlled heat (~40–42 °C) to the superficial dermis. This hyperthermia stimulates collagen and elastin without damaging the epidermis. At Renécia, I use Cristal Skin (Deleo) for its thermal stability and comfort. Duration: 30–45 min, no anesthesia required, immediate resumption.
Side effects
Transient redness, sensation of heat; no social exclusion.
What we can hope for
Immediate “radiance boost” effect, followed by progressive firming of skin texture and tone over the following weeks.
How many sessions?
Typically 6 sessions spaced 2 to 4 weeks apart, followed by periodic maintenance.
Indicative price (per session)
Face or neck: ≈ €150
Face + neck: ≈ €180
Are all machines equal?
The platforms differ in heating stability, control systems, and ergonomics. In my practice, I use Cristal Skin (Deleo) for its thermal consistency and comfort, but other devices can give good results when properly configured and used by experienced teams.
Who is the game for?
For skin combining laxity and irregularities of texture (enlarged pores, fine lines, acne scars).
How's the treatment going ?
Fine micro-needles penetrate to a controlled depth to deliver radiofrequency energy into the dermis. At Renécia, I use Genius (Lutronic) for its precision and real-time tissue feedback. Duration: 30–60 min. Topical anesthesia or MEOPA depending on the areas.
Side effects
Erythema 24–72 h, small punctiform marks 2–5 days, rare ecchymoses.
What we can hope for
Increased firmness and improved skin quality, with a reduction in fine lines and superficial scars.
How many sessions?
On average, 3 sessions spaced 4 to 6 weeks apart, followed by an annual interview.
Indicative price (per session)
Eye contour / chin: ≈ €225
Lower face: ≈ €290
Face + neck: ≈ €425
Face + neck + décolleté: ≈ €650
Are all machines equal?
Several systems coexist (Genius, Morpheus 8, etc.) with similar philosophies. I chose Genius (Lutronic) for its precise delivery and energy control during sessions in my practice. Other platforms may be relevant depending on the indication and the team's expertise.
Sofwave® – next generation ultrasound (SUPERB™ technology)
Who is the game for?
For a visible lifting effect in just one session, without surgery or downtime. Targets the face, neck and décolleté.
How's the treatment going ?
Softwave This is not a classic HIFU treatment: SUPERB™ technology delivers parallel, synchronized ultrasound beams targeting the mid-dermis (~1,5 mm). The Sofcool™ system protects the epidermis and enhances comfort. Duration: ≈ 45 minutes, without anesthesia in most cases.
Side effects
Slight redness/swelling for a few hours; no social downtime.
What we can hope for
Gradual firming from 3–4 weeks, peak at 2–3 months, lasting 12 to 24 months.
How many sessions?
Generally 1 session, reminder possible around 12–18 months.
Indicative price (per session)
Eyebrows: ≈ €800
Lower face: ≈ €1,200
Neck: ≈ €1,350
Full face: ≈ €1,560
Face + neck: ≈ €2,550
Are all machines equal?
There are different ultrasound technologies. I prefer Softwave for its reproducibility and comfort in my practice. Other devices can be adapted depending on the indication and the expertise of the team.
Collagen inducers (injections) – Sculptra® (Galderma)
Who is the game for?
Thin or devitalized faces lacking support; objective: to densify and tighten through biostimulation.
How's the treatment going ?
sculptra Polylactic acid (PLLA) is injected into the deep dermis or hypodermis. It stimulates collagen synthesis over several weeks, for a gradual and natural result.
Side effects
Slight swelling for 24 hours, possible transient bruising. Immediate resumption of activities.
What we can hope for
Skin densification, improved contour definition, firmer skin.
How many sessions?
Often 2 sessions spaced about 6 weeks apart, then remote reminder as indicated.
RRP
≈ €650 per light bulb
Are all brands equal?
Several biostimulants exist. In my practice, I favor Sculptra from Galderma (PLLA) for its clinical follow-up and the predictability of the response. Other options can be discussed on a case-by-case basis depending on the indication and the therapeutic plan.
Who is the game for?
More advanced laxity of the oval and/or neck when tissue repositioning is required without surgery.
How's the treatment going ?
Under local anesthesia, absorbable threads They are inserted through the cannula and then pulled to reposition the tissues. At Renécia, I use Croma sutures for their ease of handling and hold. Duration: ≈ 45 min.
Side effects
Tension, swelling or bruising 3–5 days; immediate result then improvement over 2–3 months; average duration ≈ 18 months.
How many wires?
Generally 6 to 10 wires depending on the area and the need.
RRP
≈ €200 per thread (number adjusted to the treatment plan).
Are all techniques equally effective?
The result depends primarily on the indication, the placement plan, and the practitioner's experience. In my practice, I use Croma threads ; other CE markings can be adapted according to the morphology and the objective sought.
