Frequently Asked Questions (FAQ)
When should I start using anti-aging serums? Dermatologists recommend starting in your mid-to-late 20s. This is when natural collagen production begins to slow down, so using serums becomes a powerful preventative step.
How do I apply serums correctly? Always apply your serum to a clean, slightly damp face after cleansing and toning. Use just a few drops and gently press it into the skin. Always follow with a moisturizer to lock it in, and neverforget your sunscreen in the morning.
Final Thoughts
Anti-aging skincare doesn’t have to be complicated. By choosing a serum with proven ingredients and using it consistently, you can effectively slow visible aging and enhance your natural glow for years to come.
