Retinol vs Tretinoin – What’s the Difference?

Both are skincare superheroes that refine texture, soften wrinkles, and unclog pores — but their strength, speed, and gentleness differ. Retinol is your gentle, over-the-counter glow starter, while Tretinoin (Retinoic Acid) is a dermatologist-prescribed powerhouse for transformative results.
