Understanding Dermatitis and Its Impact on Aesthetic Treatments

Dermatitis and aesthetic medicine: Essential considerations

Dermatitis, an umbrella term for inflammatory skin conditions, affects a significant proportion of aesthetic patients. Whether presenting as atopic dermatitis (eczema), contact dermatitis, seborrhoeic dermatitis, or perioral dermatitis, these conditions can profoundly influence treatment planning, product selection, and clinical outcomes. Understanding the relationship between dermatitis and aesthetic interventions is crucial for safe, effective patient care.

We conduct thorough skin health assessments before recommending any aesthetic treatment, so that underlying conditions like dermatitis are identified and appropriately managed to optimise results and minimise risk.

Types of dermatitis relevant to aesthetic practice

Atopic dermatitis (eczema)

The most common form, affecting up to 10% of UK adults, characterised by chronic relapsing inflammation, barrier dysfunction, and immune dysregulation. Key features include:

• Impaired skin barrier with increased transepidermal water loss
• Filaggrin gene mutations affecting up to 50% of patients
• Th2-skewed immune response with elevated IgE
• Chronic dry, itchy, inflamed skin with periodic flares

Contact Dermatitis

Allergic or irritant reactions to substances applied to the skin. Particularly relevant in aesthetics as patients may react to:

• Skincare ingredients (fragrances, preservatives, essential oils)
• Metal alloys in microneedling devices or jewellery
• Latex in clinical gloves
• Adhesives in post-treatment dressings
• Topical anaesthetics (rare but possible)

Seborrhoeic Dermatitis

Linked to Malassezia yeast overgrowth, affecting oily areas (scalp, nasolabial folds, brows). It can complicate facial aesthetic treatments by creating areas of erythema and scaling that may be mistaken for treatment reactions.

Perioral Dermatitis

Papulopustular eruption around the mouth, nose, and sometimes eyes. Particularly relevant as it can be triggered or worsened by topical corticosteroids, heavy moisturisers, and certain cosmetic ingredients.

How dermatitis affects aesthetic treatment planning

Barrier function considerations

Dermatitis patients have compromised skin barriers, meaning:

• Increased sensitivitytopical products and procedures may cause greater irritation than in healthy skin
• Enhanced absorptionactive ingredients penetrate more readily, potentially increasing both efficacy and adverse effects
• Impaired healingpost-procedure recovery may be prolonged
• Higher infection riskdamaged barrier provides less protection against microbial invasion

Treatment Timing

The cardinal rule for aesthetic treatments in dermatitis patients is: never treat during active flares. Procedures should be scheduled during periods of disease quiescence, ideally after the skin has been stable for at least 2–4 weeks. This applies to:

• Chemical peels (higher risk of irritant contact dermatitis and post-inflammatory changes)
• Laser treatments (compromised barrier increases risk of adverse outcomes)
• Microneedling (active eczema creates open wounds; procedure could spread infection)
• Injectable treatments (inflamed skin may alter product distribution and increase bruising)

Safe aesthetic treatments for dermatitis patients

Treatments generally considered safe

• Dermal fillerscan be performed during quiescent periods with appropriate aftercare
• Anti-wrinkle injectionsminimal barrier disruption; generally well-tolerated
• LED light therapynon-invasive; blue and red LED can actually benefit dermatitis by reducing inflammation and bacterial load
• Skin boosters (Profhilo)hyaluronic acid can improve hydration in atopic skin, though injection during flares is contraindicated

Treatments requiring extra caution

• Chemical peelssuperficial peels with lactic or mandelic acid may be tolerated; stronger peels carry higher risk. Patch testing is advisable
• Microneedlingcan be performed during remission with shorter needle lengths and appropriate post-care
• Laser treatmentsgenerally feasible during remission but with conservative parameters and extended healing protocols

Skincare recommendations for aesthetic patients with dermatitis

• Gentle, fragrance-free cleansersavoid foaming agents (sodium lauryl sulphate)
• Ceramide-based moisturisersrestore barrier lipids
• Niacinamidestrengthens barrier and reduces inflammation without irritation
• Introduce actives graduallyretinoids, AHAs, and vitamin C should be introduced at low concentrations with careful monitoring
• Patch test new productsapply to a small area (inner arm) for 48 hours before facial use
• Mineral-based SPFzinc oxide and titanium dioxide are less likely to irritate than chemical filters

Pre-treatment optimisation protocol

1. Weeks 1–4: Stabilise dermatitis with appropriate medical treatment (emollients, prescribed medications if needed)
2. Weeks 4–6: Establish barrier-supportive skincare regimen
3. Week 6: Assess skin stability, proceed only if dermatitis is well-controlled
4. Treatment day: Use gentle, hypoallergenic products; avoid known sensitisers in pre- and post-care
5. Post-treatment: Enhanced moisturisation protocol; delay return to active ingredients; monitor closely for flares

Frequently asked questions

Can I have Botox if I have eczema?

Yes, anti-wrinkle injections are generally safe for eczema patients, even during mild flares, as the procedure involves minimal skin barrier disruption. However, injection sites should be free from active dermatitis lesions to reduce infection risk.

Will aesthetic treatments worsen my dermatitis?

There is a risk that certain procedures (particularly chemical peels and laser treatments) can trigger dermatitis flares. This risk is minimised by treating only during remission, using appropriate protocols, and maintaining barrier-supportive aftercare. Your practitioner should be informed of your dermatitis history.

What skincare ingredients should I avoid?

Common triggers include fragrances, essential oils, sodium lauryl sulphate, certain preservatives (methylisothiazolinone), and alcohol denat. However, sensitivities vary between individuals. Patch testing can help identify your specific triggers.

Can I use retinol if I have dermatitis?

Retinol can be used by many dermatitis patients when introduced carefully, starting with low concentrations (0.025–0.05%), using short contact therapy initially, and always layering over a ceramide moisturiser. However, it should be avoided during active flares.
