Face Republic Hydro Boost Solution Serum 45 ml adds a light, water based hydration layer after toner or essence. Its smooth texture settles without a sticky finish and layers comfortably under moisturizer, sunscreen, or makeup.

Eleven forms of hyaluronic acid give the serum its fresh, moisture rich feel, while adenosine, allantoin, glycerin, and botanical extracts help keep the finish soft and comfortable.

Apply after toner or essence, then follow with moisturizer. Use morning or evening, finishing with sunscreen in the morning.

Simple serum that does its job

I was looking for basic hydration without a strong scent or a complicated routine. This spreads evenly, settles in a few seconds, and leaves my skin feeling comfortable through the evening. It does not give me a dramatic change, but it does help when my face feels tight. The order shipped quickly and the serum was packed safely with no leaks around the cap.

Helpful on air-conditioning days

My office air is extremely dry, and this has made my afternoon skincare feel less desperate. I use it after washing my face at night, mostly on my cheeks, and follow with a plain moisturizer. The serum is light enough that my skin does not feel coated. Customer service was excellent when I asked whether it could be used with my usual exfoliating toner, and they replied quickly.

Nice moisture, but do not overapply

This gives my skin a good dose of hydration, but I learned that more is not better. A larger amount stays a little sticky on my forehead and takes longer to sink in. With one thin layer, it feels comfortable and works under cream. I like the result for dry days, just not as a heavy serum mask. It is a useful product when I keep the application simple.

Layers neatly after toner

The texture is somewhere between watery and gel-like, which makes it easy to control. I use a small amount after toner and wait briefly before putting on cream. My skin feels softer and less tight, especially around my nose. It has not pilled under sunscreen for me. The bottle arrived sealed and the package was cushioned well enough that nothing shifted around in transit.

Comfortable hydration for dry cheeks

I reach for this when my cheeks feel tight after cleansing. The serum spreads easily and gives me enough slip to massage it in without rubbing. It feels hydrated but not oily once it settles, and moisturizer sits well over it. I still need a richer cream on very dry nights, but this has been a dependable extra layer for my normal routine.
