Understanding Contraindications in Aesthetic Medicine

Last updated: 5 August 2026

In aesthetic medicine, a “contraindication” is any condition, circumstance, or factor that makes a particular treatment inadvisable or potentially dangerous. Understanding contraindications is essential for patient safety and helps explain why your practitioner asks detailed medical history questions before every treatment. At Axiom Aesthetics, thorough screening for contraindications is a fundamental part of Our focus on safe, ethical practice.

Why contraindications matter

Aesthetic treatments, while generally very safe, involve real medical interventions, needles, energy devices, pharmaceutical products, that interact with the body’s biological systems. When certain medical conditions, medications, or circumstances are present, these interactions can produce adverse outcomes ranging from suboptimal results to serious complications.

Responsible practitioners screen for contraindications not to refuse treatment unnecessarily but to ensure that every treatment delivered is as safe and effective as possible. Sometimes this means delaying treatment until a temporary contraindication resolves. Other times, it means selecting an alternative treatment that is safe for the individual patient.

Absolute vs relative contraindications

Absolute Contraindications

These are conditions where a treatment must NOT be performed under any circumstances:

• The risk of harm clearly outweighs any potential benefit
• No modification of technique or parameters can make the treatment safe
• Proceeding would be medically negligent

Relative Contraindications

These are conditions where treatment may still be possible but requires:

• Modified technique, dosage, or parameters
• Additional precautions or monitoring
• Informed consent with specific risk discussion
• Medical clearance from the patient’s GP or specialist
• Careful risk-benefit assessment on a case-by-case basis

Common contraindications by treatment category

Injectable treatments (fillers, anti-wrinkle injections, biostimulators)

Absolute Contraindications

• Pregnancy and breastfeeding: Injectable products have not been tested for safety during pregnancy. While harm is not proven, the absence of safety data makes treatment inadvisable
• Known allergy to product components: True allergy to hyaluronic acid (extremely rare), botulinum toxin, or product excipients
• Active infection at treatment site: Injecting through infected tissue can spread the infection and create serious complications including abscess formation
• Active autoimmune disease affecting treatment area: Conditions like scleroderma or dermatomyositis in active flare can cause unpredictable healing responses
• Neuromuscular disorders (for botulinum toxin): Conditions like myasthenia gravis, Lambert-Eaton syndrome, or motor neurone disease, botulinum toxin can worsen neuromuscular transmission

Relative Contraindications

• Anticoagulant therapy: Warfarin, DOACs, or antiplatelet medications increase bruising risk. Treatment is possible but patients should be informed of increased bruising probability
• History of cold sores (for perioral treatments): Injectable treatments around the mouth can trigger herpes simplex reactivation. Prophylactic antiviral medication (aciclovir/valaciclovir) is recommended before treatment
• Dental procedures: The evidence supports avoiding fillers for 2 weeks before and after dental work to reduce infection risk and allow accurate assessment
• Recent vaccination: A 2-week gap between COVID or flu vaccination and injectable treatments is generally recommended to avoid confounding immune responses
• Previous permanent fillers: The presence of non-absorbable fillers (silicone, PMMA) increases the risk of complications with subsequent HA filler injections

Laser and IPL Treatments

Absolute Contraindications

• Current use of isotretinoin (Roaccutane): Impairs wound healing and increases scarring risk. A minimum 6-month washout period is required after completing the course
• Active skin infection in the treatment area: Bacterial, viral, or fungal infections can be worsened or spread by laser energy
• Pregnancy: Laser safety during pregnancy has not been established
• Photosensitising medications: Certain antibiotics (tetracyclines, fluoroquinolones), antifungals, and other medications increase the skin’s sensitivity to light, dramatically increasing burn risk
• Recent tan or sunburn: Increased melanin in tanned skin absorbs more laser energy, significantly increasing burn and pigmentation risk

Relative Contraindications

• Darker skin types (Fitzpatrick IV-VI): Some laser and IPL devices carry higher risks for darker skin. Specific wavelengths (Nd:YAG) and adapted parameters can often be used safely
• History of keloid or hypertrophic scarring: Ablative laser treatments may trigger abnormal scarring. Non-ablative treatments may be possible with careful parameters
• History of herpes simplex: Laser treatment can reactivate cold sores. Prophylactic antiviral medication is indicated
• Epilepsy: Pulsed light can theoretically trigger seizures in photosensitive epilepsy (very rare but documented)
• Active dermatological conditions: Eczema, psoriasis, and rosacea in active flare may be worsened by laser treatment

Chemical Peels

Absolute Contraindications

• Active skin infection (herpes, impetigo, warts) in the treatment area
• Open wounds or compromised skin barrier
• Current isotretinoin use (deep peels) or within 6-12 months of completing a course
• Known allergy to peel components
• Pregnancy (medium and deep peels)

Relative Contraindications

• Darker skin types: Higher risk of post-inflammatory hyperpigmentation. Superficial peels with appropriate agents (mandelic, lactic) may be used safely
• Active eczema or dermatitis
• Recent sunburn or significant tan
• Use of topical retinoids (pause 5-7 days before treatment for some peels)

Microneedling

Absolute Contraindications

• Active acne, rosacea, or eczema in the treatment area
• Active infection (bacterial, viral, fungal) at the treatment site
• Blood clotting disorders or current anticoagulant therapy (absolute for deep needling; relative for superficial)
• Current isotretinoin use
• Keloidal scarring tendency (depending on needle depth)
• Active skin cancer in the treatment area

Medication Interactions

Many common medications can interact with aesthetic treatments. Always disclose all medications, including over-the-counter products and supplements, to your practitioner:

Blood-thinning medications and supplements

These increase bruising risk with all injectable and needling treatments:

• Aspirin, ibuprofen, naproxen
• Warfarin, apixaban, rivaroxaban, dabigatran
• Clopidogrel
• Fish oil, vitamin E (high dose), ginkgo biloba, garlic supplements, evening primrose oil

Note: Do NOT stop prescribed medications without consulting your prescribing doctor. We can treat patients on blood thinners with appropriate precautions and informed consent regarding increased bruising risk.

Immunosuppressive Medications

Methotrexate, azathioprine, ciclosporin, and biological agents (adalimumab, etanercept) can impair wound healing and immune response, affecting both treatment safety and efficacy.

The consultation process

At Axiom Aesthetics, our contraindication screening is thorough but efficient:

1. Medical history form: Completed before your appointment, covering medical conditions, medications, allergies, and previous treatments
2. Verbal review: Your practitioner reviews the form with you, asking clarifying questions
3. Clinical assessment: Physical examination of the treatment area for signs of active conditions
4. Risk discussion: Any identified contraindications or risks are discussed openly
5. Informed consent: You receive clear information about both the treatment and any specific risks relevant to your individual circumstances

What happens if you have a contraindication?

Having a contraindication does not necessarily mean you cannot receive any aesthetic treatment. A careful approach is:

• Identify alternatives: If one treatment is contraindicated, another may be safe. For example, a patient who cannot have laser treatment due to photosensitising medication might be suitable for microneedling or injectable treatments
• Defer treatment: If the contraindication is temporary (pregnancy, active infection, recent sunburn), treatment is simply postponed until the situation resolves
• Seek medical clearance: For complex medical histories, we may request a letter from your GP or specialist confirming that treatment is appropriate
• Modify the approach: Some contraindications can be managed by adjusting treatment parameters, using different products, or adding precautionary measures

Frequently asked questions

Why do I need to fill out a medical form for cosmetic treatments?

Aesthetic treatments are medical procedures, and your medical history directly affects both safety and outcomes. Conditions and medications that might seem unrelated to a cosmetic treatment can significantly impact healing, increase complication risk, or interact with treatment products. The medical form protects you by ensuring your practitioner has the information needed to treat you safely. Your medical information is kept strictly confidential.

Can I have aesthetic treatments if I am pregnant?

Most aesthetic treatments are contraindicated during pregnancy and breastfeeding as a precautionary measure, as the products and technologies have not been tested for safety during pregnancy. Safe alternatives during pregnancy include gentle facials (without active acids or retinoids), certain LED therapies, and pregnancy-safe skincare. Most treatments can be safely resumed after breastfeeding is completed. Contact us if you are pregnant and interested in what safe options are available.

What should I do if I develop a contraindication between booking and my appointment?

If anything changes in your medical status between booking and your appointment, new medication, new diagnosis, pregnancy, active infection, or any other change, please inform us as soon as possible. We will advise whether treatment should proceed as planned, be modified, or be rescheduled. There is never a penalty for disclosing new medical information; your safety always takes priority over appointment schedules.

Are there long-term contraindications I should be aware of?

Some conditions represent ongoing considerations rather than temporary contraindications. Autoimmune conditions, keloidal scarring tendency, and chronic medications (such as immunosuppressants) require ongoing discussion and adapted treatment approaches rather than simple one-off screening. If you have a chronic condition, we document it in your records and factor it into every treatment decision. Your long-term treatment plan is designed around your specific medical context.

What happens if a practitioner does not ask about contraindications?

A practitioner who does not conduct thorough contraindication screening is not following accepted medical practice. This is a significant red flag. Before consenting to any aesthetic treatment, ensure that the practitioner has reviewed your medical history, current medications, allergies, and any other relevant factors. If these questions are not asked, we strongly recommend seeking treatment elsewhere. Patient safety depends on proper screening, and no treatment result is worth compromising your health.
