On May 8, 2025, Marie Claire magazine published an article titled “Is Youth Soluble?”, in which several experts analyze the role of collagen in maintaining firm skin and healthy hair. The article emphasizes that collagen is the most abundant structural protein in the human body, essential for skin, bones, tendons, ligaments, hair, and nails. However, its natural production begins to decline after the age of 25 and accelerates with menopause, potentially leading to significant collagen loss in the skin and other tissues.
Dr. Sanja Zivanovic, a biomedical expert, explains that factors such as sun exposure, poor diet, smoking, alcohol, stress, and lack of sleep can accelerate collagen loss. In addition, pharmacist Meritxell Martí, founder of Unique, points out that deep sleep is crucial for collagen production, as the growth hormone — directly linked to collagen synthesis — is released during this phase.
The article also mentions that clinical studies support the effectiveness of collagen supplements in improving skin firmness and elasticity. In this context, the Unique Pink Collagen line, formulated by Meritxell Martí, is highlighted as an expert-recommended option for those seeking to supplement their diet and care for their skin from within.
