Tazarotene is a third-generation, receptor-selective topical retinoid. It binds to retinoic acid receptors (RARs) to modulate gene expression, which increases skin cell turnover, stimulates new collagen production, and normalizes keratinocyte differentiation. This mechanism effectively reduces fine lines, smooths skin texture, and corrects uneven pigmentation caused by sun damage.
Verdict
A powerful, evidence-based topical for significant skin health and anti-aging benefits.
