Question: 1 / 400

Which of the following ingredients is commonly associated with anti-aging benefits?

Glycerin

Retinol

Retinol, a derivative of vitamin A, is widely recognized for its anti-aging benefits in skincare. It works as a powerful ingredient that promotes cell turnover, enhances skin texture, and stimulates collagen production, leading to a reduction in the appearance of fine lines and wrinkles. Additionally, retinol helps to improve skin tone and reduce hyperpigmentation, making it a sought-after component in many anti-aging products.

While glycerin is an excellent humectant that helps maintain moisture in the skin, it does not offer the specific anti-aging benefits attributed to retinol. Silicone and petrolatum serve primarily as occlusives, creating a barrier on the skin's surface to prevent moisture loss but lack the regenerative properties that target signs of aging. Therefore, retinol stands out as the most effective ingredient among the options provided for its well-documented anti-aging effects.
