Are Cheap Asian Generics Really the Same?
Yes. Tretinoin is a small, well-characterised molecule that has been off-patent since the 1980s. The active pharmaceutical ingredient is identical regardless of brand or manufacturer — what differs is the base formulation, packaging, and quality-control variance. The base only matters for tolerability (sensitive skin may prefer Retacnyl's smoother base) and shelf life (a heat-degraded tube of Retacnyl works as poorly as a heat-degraded tube of Acnetin-A). Buy fresh stock from a busy pharmacy, store it correctly, and brand-name premium is largely about packaging.
How to Spot Counterfeit or Degraded Tretinoin
- • Fresh tretinoin is pale yellow to white. Brown, orange, or dark yellow product is degraded — discard.
- • The tube should feel intact. Damaged tubes mean air exposure and oxidation.
- • Check expiry dates. Tretinoin typically has 2-3 years from manufacture; pharmacies with low turnover may stock close-to-expiry tubes.
- • Buy from air-conditioned pharmacies. Heat destroys tretinoin. Avoid pharmacies that display product in unconditioned windows.
- • Verify printed details. Brand name, strength, lot number, and expiry should all be clearly printed (not stickered or smudged).
