For what purpose are placentary extracts used in cosmetics?

Placentary extracts are primarily used in cosmetics for their skin-activating benefits. These extracts are rich in proteins, vitamins, and growth factors that can stimulate cellular activity and promote skin regeneration. The use of placentary extracts is grounded in their ability to enhance the overall health and appearance of the skin by improving elasticity, hydration, and texture. This activation at the cellular level can lead to a more youthful-looking complexion, making it a sought-after ingredient in various skincare formulations.

While enhancing fragrance, adding color, and providing sun protection are important aspects of cosmetic products, they do not directly relate to the fundamental role of placentary extracts. These extracts do not function as colorants or fragrances, nor do they provide effective sun protection compared to dedicated sunscreen ingredients. Their primary application lies in rejuvenating and energizing the skin, which aligns with the answer related to skin activation.
