Tretinoin Tretin 0.05% Cream USP

No. Tretinoin is a retinoid and is classified as teratogenic — it poses significant risks to a developing fetus. It must not be used during pregnancy or while breastfeeding. If you are pregnant, planning to become pregnant, or nursing, discontinue use immediately and consult your doctor. Use effective contraception while on tretinoin therapy.

Yes. This product is fungal acne safe. It contains no ferments, fatty acid esters, polysorbates, or oils that feed Malassezia yeast. The minimal 3-ingredient formula (tretinoin, BHT, sorbic acid) avoids the common triggers associated with fungal acne breakouts. Tretinoin itself can help by accelerating cell turnover and keeping pores clear.

Use caution when combining. Do not layer additional retinol or retinoids on top of tretinoin — this doubles irritation without added benefit. Vitamin C (L-ascorbic acid) can be used in your AM routine while tretinoin is used at PM. AHAs (glycolic, lactic acid) and BHAs (salicylic acid) should be introduced very cautiously and on alternate nights, not the same night as tretinoin, to avoid over-exfoliation and barrier damage. Always consult your dermatologist before combining actives.

Tretinoin 0.05% works best for oily, combination, and acne-prone skin types. These skin types tend to tolerate the drying effects more easily and benefit most from the sebum-regulating properties. Dry skin types can use it but should pair with rich moisturizers and start very slowly. Sensitive or eczema-prone skin may find 0.05% too strong — consider starting with 0.025% instead.

Expect initial retinization (dryness, peeling) in weeks 1–2 and possible purging in weeks 2–6. Most users begin to see visible improvement in skin texture and acne reduction by weeks 6–12. Significant anti-aging benefits (reduced wrinkles, faded dark spots, improved firmness) typically become noticeable after 3–6 months of consistent nightly use. Full collagen remodeling benefits continue to develop over 12+ months.

Apply at night only, after cleansing and toning. Wait 20–30 minutes after washing for skin to dry completely, then apply a pea-sized amount as a thin layer. Follow with moisturizer. In the morning, apply your usual routine and finish with SPF 30+ sunscreen. If you experience excessive dryness, use the sandwich method: moisturizer first, then tretinoin, then another layer of moisturizer.

The overall comedogenic rating for this product is low (1/5). The listed key ingredients (tretinoin, BHT, sorbic acid) are non-comedogenic. However, the standard USP cream base typically includes isopropyl myristate, which has a comedogenic rating of 5/5 when evaluated as a standalone ingredient. In practice, the small amount in the formulation combined with tretinoin's pore-clearing action means clogging is unlikely for most users. If you are extremely clog-prone, consider asking your dermatologist about a gel formulation instead.

Use within 6 months of opening for best potency and safety. Tretinoin degrades when exposed to light, air, and heat. Store below 27°C (80°F), keep the tube tightly closed, and never leave it in direct sunlight or a hot bathroom. The sealed shelf life before opening is typically 24–36 months from manufacture date. Check the expiry date printed on the tube and packaging.
