Who qualifies
Tretinoin 0.05% cream is a prescription-only topical retinoid indicated for skin ageing and photoageing. An EU-licensed doctor evaluates every submission individually to ensure treatment is safe and clinically indicated.
Eligible patients
- Adults aged 18 and older seeking treatment for photoageing, fine lines, or skin texture irregularities.
- Patients who provide clear facial photographs for visual clinical review.
- Individuals committed to applying broad-spectrum daily SPF protection.
Clinical exclusions and referrals
- Pregnancy: Tretinoin is strictly contraindicated during pregnancy and while actively trying to conceive.
- Severe skin conditions: Hi-Doctor provides topical treatments only. Oral isotretinoin, oral antibiotics, and severe, nodular, cystic, or scarring skin disease are referred to in-person clinical care.
- Unscreened skin lesions: Suspicious moles or active inflammatory lesions requiring in-person dermoscopy must be examined at a physical clinic.
What Tretinoin actually does
Tretinoin (all-trans retinoic acid) is the topical retinoid with the deepest clinical evidence base for treating photoageing. It binds directly to nuclear retinoic acid receptors, stimulating rapid keratinocyte turnover and promoting dermal type I collagen synthesis.
Because structural collagen remodeling in the dermis takes time, visible improvements develop over several months. Consistent application and tolerance-building are essential for clinical efficacy.
| Timeline | Biological Mechanism | Clinical Expectation |
|---|---|---|
| Weeks 2–6 | Accelerated epidermal turnover (retinisation phase). | Dryness, mild peeling, temporary redness, and skin sensitivity. |
| Week 12 | Epidermal compaction and normalized cellular shedding. | Smoother skin texture, improved tone, and increased radiance. |
| Months 6–12 | Dermal collagen I synthesis and extracellular matrix repair. | Gradual softening of fine lines and improved dermal firmness. |
Side effects and when to stop
Most patients undergo an initial retinisation period lasting 2 to 6 weeks. To minimize irritation, apply a pea-sized amount to clean, completely dry skin at night, starting 2 to 3 nights per week before gradually increasing frequency.
- Expected adjustments: Localized flaking, mild stinging, and surface dryness are common during the initial weeks.
- Mandatory sun protection: Tretinoin increases photosensitivity. Applying daily broad-spectrum SPF is mandatory throughout treatment.
- When to discontinue: Stop treatment and consult a doctor if you experience severe contact dermatitis, facial swelling, blistering, or if you become pregnant.
