Botox or dermal fillers — which one do I need?

Botox vs. dermal fillers — what's the difference and which is right for you? A San Mateo physician explains when to use each.

Photo Facials

They solve different problems. Botox relaxes muscles to soften lines caused by movement — forehead lines, frown lines between the brows, and crow’s feet. Dermal fillers add volume to areas that have lost fullness — cheeks, lips, and under-eye hollows — and can smooth deeper folds.

A simple way to think about it:

  • Lines when you move (smiling, frowning) → usually Botox.
  • Lost volume or lines at rest (flatter cheeks, thin lips, deeper folds) → usually fillers.

Many patients benefit from a combination, which is why an in-person assessment matters. Dr. Susan Lin, M.D. evaluates your face at rest and in motion and builds a plan so you still look like yourself — just refreshed. Both are FDA-cleared and, in experienced physician hands, have strong safety profiles. Results vary by individual.

Schedule a consultation to find your right plan.
