Probiotic Boost Serum

$62.00

barrier-restoring • plumping • soothing

Supercharge your routine with a serum designed to amplify the performance of every product that follows. Powered by hyaluronic acid, it draws deep hydration into the skin, plumping cells from within and maximizing moisture retention. Living probiotics replenish the skin’s microbiome with beneficial flora, helping to restore balance, resilience, and glow. Use it as the first step after cleansing to create the perfect canvas for your skincare ritual.

Size
This juicy serum provides skin with a daily dose of live probiotics + hyaluronic acid to balance the microbiome, restore collagen, and hydrate skin’s deepest layers. This tonic works in tandem with your favorite EarthTonics moisturizer (think Mushroom Mylk or Repair Creme) as a hydration magnet that delivers their potent botanical actives even deeper. Notice visibly plumper, clearer, dewier skin with everyday use. Beloved by those with reactive & sensitive skin.

Probiotic Benefits for your Skin
Just like the gut, your skin has its own microbiome — a living network that supports barrier strength, hydration, and inflammation response. Our live probiotics nourish this ecosystem by introducing beneficial strains that naturally crowd out the bacteria linked to irritation and breakouts, helping skin stay balanced, clear, and resilient.
