It's not your skin. It's the mechanism.
Every serum you've tried made the same promise β then sat right on top of your skin. Their molecules are too big to get past the surface, so they hydrate for a few hours, wear off, and never reach the deeper layer where firmness comes from.
You're not doing it wrong β the mechanism is. Bee venom is small and active enough to sink past the surface and reach that layer, gently signalling your skin to firm, plump and smooth itself.
