To choose the right serum, identify your specific skincare goals and concerns, such as anti-aging, hydration, or brightening. Look for serums with key ingredients like hyaluronic acid for hydration, vitamin C for brightening, or retinol for anti-aging, tailored to your needs. Consider your skin type, whether it's dry, oily, or sensitive, and choose a serum with a texture that suits you (e.g., lightweight for oily skin, richer for dry skin). Test new serums with a patch test, and read reviews from others with similar skin concerns to find the best serum for your skincare routine <3
