Troubleshooting common serum issues
No visible change after two or three months: confirm that you are using the serum most days, pairing it with daily sunscreen, and giving it at least 8–12 weeks; if there is still no difference, you may need a different active ingredient or a dermatologist’s help with stronger options.

Building a safe AM–PM routine with face serums
Give serums enough time to work Hydrating serums with ingredients like hyaluronic acid can make skin feel softer and look plumper within days.Changes in pigmentation and fine lines are slower; many brightening and anti‑ageing serums need around six to twelve weeks of consistent use, plus daily sunscreen, before you can fairly judge them.Simple routines that focus on a gentle cleanser, targeted serums, moisturiser, and sunscreen often hold up better over time than constantly changing, complicated line‑ups.
