What should you know about Janssen Retin-A?

Tretinoin changes how skin cells develop and shed. It may be prescribed for acne and may also be used in selected skin-care plans for changes in texture or uneven pigmentation. The product name alone does not tell you which strength, vehicle or schedule is appropriate.

Dryness, flaking, stinging and redness can occur when treatment begins or when the skin barrier is irritated. These effects do not mean you should push through severe discomfort. Eczema-prone, sunburned or recently treated skin may need a different plan.

Use tretinoin exactly as directed. Apply a small amount to clean, fully dry skin if your clinician advises, avoid the eyelids and lip corners, and wash your hands afterwards. Start or adjust frequency only according to the plan you were given. A bland moisturiser can support comfort, while daytime broad-spectrum sun protection helps limit irritation and pigment change.

Do not layer it casually with harsh scrubs, waxing, strong exfoliating acids or other irritating products. Tell your clinician about pregnancy, plans for pregnancy, breastfeeding, allergies and other medicines before use. For context, see Tretinoin and Topical Retinoids.

Stop and seek medical advice for marked swelling, blistering, severe burning, facial swelling, eye symptoms or a spreading rash. Contact a clinician if irritation remains intense despite following the plan, or if acne becomes painful and rapidly worsens. Urgent help is appropriate for breathing difficulty or swelling of the lips or tongue.

Which tretinoin strength and formulation am I using? How often should I apply it, and where should it be avoided? What should I do after a missed application? Which cleanser, moisturiser and sunscreen fit my skin? Should I pause before waxing, a peel or another procedure? What symptoms mean I should stop and call?
