What ingredient derived from yeast is known to help reduce fine lines and wrinkles?

Beta-glucans
Hyaluronic acid
Amino acids
Collagen

The correct answer is: Beta-glucans

Beta-glucans, derived from yeast, are known for their ability to enhance skin hydration and improve the overall appearance of the skin. These polysaccharides can boost the skin's natural barrier function and promote healing, which can be beneficial in reducing the visibility of fine lines and wrinkles. Their ability to retain moisture helps plump the skin, making it appear smoother and more youthful. Additionally, beta-glucans have anti-inflammatory properties that can enhance skin tone and texture, further contributing to an ageless appearance. In contrast, hyaluronic acid is a well-known humectant that draws moisture to the skin but is not specifically derived from yeast. Amino acids are crucial components of proteins and can promote skin health but don’t directly target fine lines and wrinkles in the same manner as beta-glucans. Collagen, although essential for skin structure and elasticity, is a protein that does not directly come from yeast and is primarily aimed at providing structural support rather than actively reducing wrinkles.
