Which ingredient is recognized for improving oxygen uptake in skin cells?

Retinol
Glycoprotein
Polyglucans
Liposome-based products

The correct answer is: Glycoprotein

Glycoprotein is recognized for its role in improving oxygen uptake in skin cells, which contributes to cellular respiration and overall skin health. Glycoproteins are molecules that consist of a protein bonded to carbohydrates. They play a crucial role in various biological processes, including the maintenance of skin's structural integrity and hydration. By enhancing the transport of oxygen to skin cells, glycoproteins can help improve skin vitality and facilitate better nutrient absorption, ultimately leading to healthier, more radiant skin. In contrast, while retinol is known for its ability to stimulate collagen production and improve skin texture, it does not specifically enhance oxygen uptake. Polyglucans, although beneficial for hydration and skin barrier function, primarily focus on maintaining moisture levels rather than oxygen delivery. Liposome-based products are designed to encapsulate active ingredients for better absorption but do not directly enhance oxygen uptake in skin cells.
