Understanding the difference between dry and dehydrated skin is crucial for effective skincare. Dehydrated skin lacks water, while dry skin lacks oil. Incorporate these expert tips into your routine to achieve optimal hydration: use sunscreen, consider advanced treatments like Profhilo and Viscoderm Hydrobooster, invest in a humidifier, prioritize hydration through water intake, and make healthy dietary choices. Avoid harsh cleansers, exfoliate weekly, and look for skincare products containing hydrating ingredients like hyaluronic acid, glycerin, and ceramides.
