Retinal, or retinaldehyde, is a powerful retinoid and a direct precursor to retinoic acid, offering significant anti-aging benefits with less irritation than tretinoin. In Korean skincare, it is valued for its efficacy in promoting cell turnover and collagen production, making it ideal for individuals targeting visible signs of aging like wrinkles, fine lines, and uneven skin tone. This ingredient is suitable for those seeking advanced solutions to improve skin texture and firmness.
