How to Use

Simple Daily Application Guide

Integrate this potent probiotic ampoule seamlessly into your daily regimen. This simple three-step guide shows you how to layer it effectively for maximum absorption and benefits, helping you achieve a fortified, glowing complexion.

Dispense and Prepare the Serum

After cleansing and applying any toner, dispense two to three drops of the clear ampoule serum onto your fingertips. The lightweight, water-like texture makes it easy to control the amount without waste, preparing it for even distribution across your skin.

Apply with a Gentle Patting Motion

Gently pat the serum onto your face and neck using your fingertips. Avoid rubbing; the patting motion encourages the fast-absorbing formula to penetrate more effectively, delivering its probiotic benefits deep into the skin without tugging or pulling.

Follow with Moisturizer to Seal

Allow a moment for the serum to fully absorb into your skin, which happens quickly. Once absorbed, it leaves no sticky residue, creating the perfect canvas. Follow with your favorite moisturizer to lock in the hydration and seal in the probiotic benefits.

I was looking for a dupe for a luxury serum and found this. It has the same key ferment ingredient at a higher percentage, without the alcohol. The thin texture absorbs instantly and fits perfectly into my routine. My skin feels firmer and looks brighter. I'm already on my second bottle and will keep buying.

This is my third bottle! I love the clean ingredient list—no fragrance, no alcohols, no essential oils. It's a safe haven for my sensitive skin. It provides deep hydration without irritation, and my skin barrier feels noticeably healthier and more resilient since I started using it daily.

Amazing serum, it's the only constant in my routine for the past two years. The ingredient list is great, it's fragrance-free, and very hydrating. It gives my skin a nice, healthy glow and I really love how it makes my complexion look and feel every morning.

This lightweight, runny serum absorbs quickly into my dry, mature skin and provides comfortable hydration throughout the day. It feels refreshing when applying, spreads easily, and my skin looks smooth and feels soft. It doesn't irritate my skin at all, even after exfoliating, and wears beautifully under foundation.

I use this when my skin feels reactive and sensitive. It's incredibly calming and hydrating, and it truly helps keep my skin barrier healthy. It's become a must-have for me, especially on nights when I use stronger treatments like tretinoin, to keep my skin barrier happy and strong.
