Supercharge your beauty sleep. Cosmedix Reboot Overnight Hydration Serum enhances the results of any skincare routine, ensuring your skin’s microbiome is being properly nourished.

With gentle active naturals including aloe and coconut extract, skin is repaired and hydrated when it will benefit most - while you sleep. Cosmedix Reboot Serum has a minimal ingredients list, making it perfect for sensitive skin types.


  • Repairative, hydrating night serum featuring probiotics
  • A mid-weight, spreadable gel-like serum that isn’t too rich
  • For all skin types, especially dehydration prone
  • Plumps the appearance of fine lines
  • Gentle, minimal serum ideal for sensitive skin
  • Restores and protects from long-haul flights
  • Probiotic lactobacillus ferment helps to balance the skin microbiome
  • Coconut Extract defends the skin and helps lock in moisture
  • Aloe vera soothes and protects the skin, particularly for sensitive skin
  • Saccharide Isomerate helps the skin retain hydration and gives an instant boost


Cosmedix Reboot Serum may be used as a solo hydrating serum underneath your night cream or sleep mask, or it may be used to lock in the effects of your existing serums. Works particularly well as serum that boosts the effect of hyaluronic acid serums, or exfoliating options such as retinols or AHA-packed serums.
