Aesthetic Procedures: What Works and What Is Marketing
An evidence-based look at cosmetic procedures: botulinum toxin and fillers, lasers, SMAS lifting, HydraFacial, cryolipolysis and microneedling — where the effect is proven and where it isn't.
Contents
Aesthetic and injectable cosmetology promises a lot — from "ten years younger" to "a lift without surgery." Reality varies: injections (botulinum toxin, fillers) and lasers have good evidence; device lifting and cryolipolysis are moderate; care procedures like HydraFacial are cosmetic and short-lived. Here is a method-by-method look, without inflated expectations.
Injections: the best evidence
Botulinum toxin relaxes expression muscles and smooths movement lines (forehead, glabella, crow's feet). Studied for decades, predictable, lasting 3–4 months. Nearly all risks (asymmetry, eyelid ptosis) relate to technique, not the product — hence an experienced practitioner matters.
Fillers (usually hyaluronic acid) restore volume and soften deep folds. The effect is immediate and lasts from months to a year or two. The key risks are vascular complications from incorrect injection — again a matter of skill.
Lasers: targeted and appropriate
Laser and light technologies are a working tool for specific goals:
| Goal | What is used | Evidence |
|---|---|---|
| Pigmentation, vessels | IPL, specialized lasers | Good |
| Texture, fine lines, scars | Fractional laser | Good |
| General 'rejuvenation' | Phototherapy | Moderate |
Device lifting and contouring
SMAS lifting (ultrasound) and RF lifting stimulate collagen and give moderate tightening; the effect develops over 2–3 months and lasts a limited time. Know the limit: with marked tissue descent this is only slight improvement, not an alternative to surgery.
Cryolipolysis (freezing fat cells) has moderate evidence for localized deposits — reducing a pinch by a few millimetres. It is contouring, not weight loss.
What to choose
Start with the goal — movement wrinkles, pigmentation, volume or contour: each has its own method, and "do everything at once" is rarely needed. Then it is not the device brand that decides but a licensed clinic and a practitioner experienced in that procedure. Home gadgets and skincare do not replace this, but procedures do not cancel the basics either — sunscreen and retinoids.

Bottom line
Cosmetology works, but selectively and temporarily: injections and lasers predictably, device lifting and cryolipolysis moderately, care procedures cosmetically. What most affects the result is not the choice of a trendy device but the practitioner's hands and sober expectations.
FAQ
Which cosmetic procedures actually work?+
Injections have the best evidence: botulinum toxin for expression lines and fillers for restoring volume — predictable but temporary. Lasers work well on pigmentation, vessels and texture. Device lifting (SMAS/RF) and cryolipolysis give a moderate effect. HydraFacial is a care procedure, not anti-aging.
Is Botox harmful?+
At cosmetic doses botulinum toxin has been studied for decades and is considered safe in skilled hands. The effect is temporary — 3–4 months — then the muscle recovers. Risks relate mostly to injection technique (asymmetry, eyelid ptosis), so the practitioner's skill matters more than the product.
Does SMAS lifting tighten without surgery?+
Device methods (ultrasound SMAS, RF lifting) give moderate skin tightening by stimulating collagen; the effect develops over 2–3 months and lasts a limited time. It is not a substitute for a surgical lift: with marked tissue sagging a device gives only slight improvement.
Does cryolipolysis work on fat?+
Cryolipolysis (freezing fat cells) has moderate evidence for localized fat — reducing a pinch by a few millimetres per session. It is contouring, not a weight-loss method: it does not affect overall weight.
What is HydraFacial and is it worth it?+
It is a device facial with cleansing, exfoliation and serum application. Skin looks fresher afterwards, but it is cosmetic care with a short-term effect, not anti-aging. Keep expectations at 'polished look for an event,' not 'years younger.'
How do you choose a procedure and avoid trouble?+
Start with the goal: wrinkles, pigmentation, volume or contour — each has its own method. Then a licensed clinic and a practitioner experienced in that specific procedure, an honest talk about realistic results and contraindications. Avoid promises of a 'permanent result in one session' — a marker of poor practice.
