During winter, the skin is exposed to cold air and low humidity, which can compromise its natural barrier and lead to increased dryness and irritation. Scientifically, the skin needs enhanced hydration and gentle care to maintain its health during these conditions. Applying hyaluronic acid boosts the skin's moisture retention due to it's ability to attract and hold water molecules. Exfoliation gently removes dead skin cells without stripping essential lipids, promoting healthy cell turnover and improving texture. Photobiomodulation stimulates collagen synthesis, rejuvenating the skin from within. Incorporating these evidence-based methods helps strengthen the skin's barrier, keeping it hydrated and resilient throughout the winter months.
