What Is Medical Aesthetics?

Medical aesthetics is a broad term covering nonsurgical or minimally invasive medical procedures intended to improve skin appearance, facial contour and certain aesthetic changes associated with ageing.

These procedures can include botulinum toxin injections, dermal fillers, selected injectable skin treatments, platelet-rich plasma and various energy-based procedures.

Because many of these treatments involve needles, cannulas or medical devices, describing all medical aesthetic procedures as completely “non-invasive” is inaccurate.

Medical aesthetic procedures should not be treated as ordinary beauty treatments. Product selection, dose, injection site, individual anatomy and medical history can affect both results and the risk of complications.

Which Medical Aesthetic Treatments Are Used?

Procedures vary according to the individual's needs and clinical assessment.

Common approaches can include:

  • Botulinum toxin injections
  • Hyaluronic acid and other appropriate dermal fillers
  • Mesotherapy and selected injectable skin treatments
  • Platelet-rich plasma treatments
  • Laser and other energy-based treatments
  • Other individually selected skin rejuvenation procedures

The level of scientific evidence, approved indications, potential benefits and risks differ between treatments.

What Is Botulinum Toxin Treatment?

Botulinum toxin temporarily reduces nerve signalling to the injected muscle, decreasing muscle activity for a limited period.

For aesthetic purposes it can be used for dynamic facial lines such as:

  • Frown lines
  • Forehead lines
  • Certain lines around the eyes

Botulinum toxin also has medical indications, including chronic migraine, excessive sweating and certain neuromuscular conditions. Cosmetic and therapeutic indications, however, can involve different doses, injection patterns and approved products.

Its effect is temporary and duration varies according to the product, dose, treatment area and individual factors.

Botulinum toxin is a medical drug. Unapproved, counterfeit, improperly stored or otherwise unreliable products can cause serious adverse effects.

What Are Dermal Fillers?

Dermal fillers are injectable products used to support volume, modify facial contour or reduce the appearance of selected folds and depressions.

Hyaluronic acid is one of the most commonly used filler materials. Products containing other materials, such as calcium hydroxylapatite, can also be used for selected indications.

Different products and techniques can be used for the cheeks, lips, chin, jawline and other facial areas.

Results depend on the filler material, volume injected, anatomical area and individual tissue structure.

Dermal fillers can rarely cause serious vascular complications.

Accidental injection into a blood vessel can cause skin necrosis, visual impairment or blindness and, very rarely, stroke. Unusual severe pain, blanching or mottled skin and any change in vision require urgent medical assessment.

What Are Mesotherapy and Injectable Skin Treatments?

Mesotherapy is a broad technique in which small amounts of substances are delivered through multiple injections into the skin or selected superficial tissue layers.

Products may contain hyaluronic acid, amino acids or other ingredients, but the term “mesotherapy” does not describe one standard product or one standard treatment.

Effectiveness and safety depend on the substance used, regulatory status, dose, injection technique and intended indication.

Claims that all vitamin-containing mesotherapy mixtures reliably rejuvenate the skin are not supported by consistent scientific evidence. Research findings vary substantially between products and protocols.

PRP and Hair Treatments

Platelet-rich plasma (PRP) is prepared from a person's own blood and contains a higher concentration of platelets before being administered to a selected treatment area.

PRP has been studied particularly in androgenetic alopecia.

A 2024 systematic review and meta-analysis of randomised trials reported improvement in hair density, although study methods were highly heterogeneous and the overall certainty of evidence was considered low.

PRP should therefore not be described as a treatment that reliably stops every type of hair loss or produces identical results in every patient.

Stem-cell, exosome and other regenerative products are not the same as PRP. Evidence, safety and regulatory approval must be evaluated separately for each product and intended use. Unproven cellular products should not be promoted as routine or guaranteed hair-loss treatments.

Who May Be Suitable for Medical Aesthetic Procedures?

Medical aesthetic procedures can be considered in appropriate adults following an individual assessment.

Not every person is suitable for every procedure.

Before treatment, factors such as medical conditions, medications and supplements, allergies, pregnancy or breastfeeding, active infections or skin disorders, previous aesthetic procedures and individual expectations should be reviewed.

What Are the Risks and Side Effects?

A procedure being nonsurgical does not mean that it is risk-free.

Depending on the treatment, possible effects can include:

  • Pain or tenderness
  • Swelling and bruising
  • Redness
  • Infection
  • Asymmetry or an undesired aesthetic result
  • Allergic or inflammatory reactions
  • Nerve or vascular injury

The type and likelihood of complications differ between procedures, making individual counselling and informed consent important.

Why Does the Clinical Setting Matter?

Performing medical aesthetic procedures in a hospital or healthcare setting can provide access to additional medical specialties and emergency support if a complication occurs.

However, a hospital setting alone does not guarantee a better result or eliminate complications.

Important safety factors include practitioner competence, appropriate patient selection, traceable and reliable products, suitable hygiene standards, early recognition of complications and a clear emergency-management plan.

How Should a Practitioner and Treatment Centre Be Chosen?

A decision should not be based solely on price or social-media images.

Before treatment:

  • Confirm the practitioner's relevant training and qualifications.
  • Ask which product will be used.
  • Ensure the product is original, appropriately stored and traceable.
  • Discuss realistic outcomes and limitations.
  • Ask about common and rare complications.
  • Ask how complications would be managed.
  • Tell the practitioner about previous fillers and aesthetic treatments.
Needle-free high-pressure filler devices should not be considered a safe substitute for conventional dermal-filler injection. The FDA has not approved needle-free devices for dermal filler injection and has reported serious injuries associated with their use.

Medical Aesthetic Treatment Should Be Individualised

The appropriate treatment, product and dose should be selected according to individual anatomy, medical history, expectations and the specific risk profile of the procedure.

Frequently Asked Questions

What is medical aesthetics?
Medical aesthetics is a broad term covering nonsurgical or minimally invasive medical procedures intended to improve skin appearance, facial contour and certain aesthetic changes associated with ageing.
Are medical aesthetic treatments completely risk-free?
No. Being nonsurgical does not mean that a treatment is risk-free. Temporary effects such as swelling and bruising can occur, together with less common complications including infection, allergic reactions, asymmetry and vascular complications with certain injections.
Can dermal fillers be dangerous?
Swelling, bruising and tenderness are more common. Rarely, accidental injection into a blood vessel can cause skin necrosis, vision loss or stroke. This is why fillers should be administered by an appropriately qualified healthcare professional familiar with facial anatomy and complication management.
Is botulinum toxin permanent?
No. The effect of botulinum toxin on muscle activity is temporary. Duration varies according to the product, dose, treatment area and individual factors.
Is mesotherapy scientifically proven?
Mesotherapy is not one standard treatment. Effectiveness depends on the substance used, technique and intended indication. Some products have supportive studies, but evidence for the many mixtures promoted for general skin rejuvenation remains heterogeneous.
Can PRP help hair loss?
PRP has been studied particularly for androgenetic alopecia, and some trials report improved hair density. However, treatment protocols vary substantially and the certainty of evidence remains limited. It does not provide the same result for every type of hair loss.
Is having a medical aesthetic procedure in a hospital safer?
A hospital or healthcare setting can provide access to additional medical support if a complication occurs. However, the main determinants of safety are appropriate patient selection, practitioner competence, reliable products, suitable hygiene and an effective complication-management plan.
Academic Hospital note: There is no single medical aesthetic procedure or standard dose that is suitable for everyone. Treatment and product selection should be based on individual anatomy and medical assessment. You can book an appointment.
