Retinal and Retinol are two of the most powerful vitamin A derivatives in skincare, known for their unmatched ability to smooth fine lines, boost collagen, and refine uneven texture. Retinol works gradually to improve wrinkles, firmness, and clarity, making it ideal for beginners or sensitive skin. Retinal (Retinaldehyde) is its stronger, faster-acting cousin - delivering quicker, more visible results with less irritation than prescription retinoids. Both ingredients help unclog pores, fade acne marks, brighten dullness, and accelerate cell turnover, giving the skin a smoother, clearer, more youthful appearance. Together, they’re the gold standard for anti-aging and resurfacing in Korean skincare.
