Research published in ‘Nature Aging’ indicates that biological aging may occur in waves rather than a linear progression, with significant shifts in metabolism, immune function, and skin health occurring around the mid-40s and early 60s. Dermatologists note that skin dryness, or xerosis, can worsen the visibility of these aging markers by compromising the skin barrier. Factors contributing to dryness include genetics, environmental conditions like low humidity, and skincare habits such as over-cleansing.

Lifestyle and dietary choices significantly influence aging. Experts, including nutritional medicine expert Dr. Matthias Riedl, identify nicotine and excessive alcohol consumption as accelerators for wrinkle formation and inflammation. Alcohol can cause dehydration and the visible expansion of fine facial blood vessels. Additionally, nutritional deficiencies and diets causing rapid blood sugar spikes can impact skin elasticity.

As aging progresses, particularly after age 40, facial definition may decrease—a phenomenon sometimes described as a ‘melted face’ appearance—due to reduced bone density, changes in fat compartments, and declining collagen and elastin. Hormonal shifts, such as the drop in estrogen during menopause, further contribute to thinner, less hydrated skin. 

To address these changes, new skincare solutions like the NIVEA Q10 Collagen Expert series utilize Q10, collagen peptides, and ceramides to support cellular energy and moisture retention. While collagen-based products assist with hydration, dermatologists note that retinol has more consistent evidence for treating fine lines and photoaging, emphasizing that hydration and sun protection remain essential.
