Adult Dosing
Acne vulgaris
0.025% cream or gel — apply a thin pea-sized amount to affected area at night
Once nightly; long-term use (at least 12 weeks for full benefit)
Start with lowest concentration (0.025%) and increase to 0.05–0.1% as tolerated. Wash face, pat dry, wait 20–30 minutes, then apply (reduces irritation).
Photoaging / fine lines / hyperpigmentation
0.025–0.05% cream nightly to face
Once nightly; long-term — benefits seen at 3–6 months
Use moisturiser before/after to manage irritation. SPF mandatory in the morning. Combination with hydroquinone (Kligman formula) enhances effect for melasma.
Pregnancy & Lactation
Pregnancy: Category C
Topical tretinoin — systemic absorption is minimal but measurable. Oral retinoids (isotretinoin) are teratogenic; topical form carries theoretical risk especially in the first trimester. Generally advised to avoid, particularly in first trimester; use only if clearly needed with informed consent.
Lactation: Caution
Topical absorption is low. However, avoid application to breast area. Caution in breastfeeding — limited data on infant exposure.
Top Drug Interactions
| Interacting Drug | Effect | Severity |
|---|---|---|
| Benzoyl peroxide | Benzoyl peroxide may oxidise and inactivate tretinoin — apply at different times of day (benzoyl peroxide AM, tretinoin PM) | Moderate |
| Other topical retinoids (adapalene, tazarotene) | Additive irritation, dryness, and peeling — do not use multiple topical retinoids simultaneously | Moderate |
| Photosensitising drugs (tetracyclines, sulfonamides, fluoroquinolones, thiazides) | Additive photosensitivity — increase sun protection measures | Minor |

Monitoring Required

- Acne response — improvement in comedone and inflammatory lesion count at 12 weeks
- Hyperpigmentation monitoring in darker Fitzpatrick skin types (III–VI)
Patient Counseling Points
- Apply only at night — tretinoin breaks down in sunlight and causes photosensitivity
- Use a broad-spectrum SPF 30+ sunscreen every morning without exception
- Start 2–3 nights per week and increase gradually to nightly as your skin adjusts
- Apply a pea-sized amount — more is not better; excess causes irritation
- Wait 20–30 minutes after washing and drying your face before applying (damp skin increases irritation)
- Your skin will peel and may worsen in the first 4–8 weeks — this is normal purging; do not stop
- Apply a gentle, fragrance-free moisturiser to manage dryness
- Avoid waxing, dermabrasion, or harsh chemical peels while using tretinoin
- Do not apply to eyes, nostrils, or mouth — rinse immediately if contact occurs
