Prevention in skincare focuses on protecting the skin from future damage and maintaining its health and appearance over time. It involves daily habits like using broad-spectrum sunscreen to guard against UV damage, applying antioxidants to defend against environmental stressors, and keeping the skin hydrated to preserve its barrier function. Preventative care also includes gentle cleansing, avoiding harsh products, and addressing early signs of aging or discoloration before they progress. Consistent prevention helps maintain a youthful, even-toned, and resilient complexion for the long term.
