Ceramides are considered to play a key function in both retaining moisture and protecting the skin from external stimuli. However, ceramides in human skin gradually decrease with age, researches has shown that by the time of 50s the amount of ceramides will be the half of 20s. Based on the fact, the high-quality ceramides have developed in Japan over many years. Our proprietary ceramides can penetrate the skin without compromising its function and retain moisture longer, leaving the skin firm and hydrated.


Skin with ceramide loss is difficult to get skincare benefits even with effective formulations. There is a high possibility that the formula will not penetrate deep into the skin and evaporate due to dryness. So the key is to fill the stratum corneum with ceramide first and create a base for toners and serums to get the maximum effects. Our Boost Serum works to promote deeper penetration of toners and serums for lasting results.

Great Serum

I love Japanese skin care and this is one of the best!
Sensitive skin friendly and works great.
Ita?s pricey but all you need is 2 pumps and last long time.
I have sensitive dry skin and this doesna?t cause any irritation or redness but make my skin smooth and well hydrate.
If you have sensitive skin, this is highly recommended!!!

Gentle and lightweight

This is a gentle and lightweight day serum for sensitive skins. Very soft and subtle feel on the face without leaving a residue. Non-irritating. Great for oily or combination skins.

Very light serum which left my sensitive skin clear and feeling silky

My Skin Type: Pale, dry, sun-damaged, sensitive, prone to redness
My AM Facial Routine: Wash/exfoliate, serum, moisturizer with SPF
My PM Facial Routine: Wash, serum, heavier overnight moisturizer
My Review of this product:
Pros: Very lightweight-almost as thin as water, no discernable scent, absorbs quickly into skin, no stickiness after application, left skin feeling incredibly silky, works well under regular moisturizer, attractive bottle would look nice on any vanity
Cons: The waterlike viscosity makes it a little difficult to apply so you end up using more than necessary. It's relatively expensive for the size bottle and the amount you need to apply

Very Nice

Incredibly nice for people with sensitive skin. It's one of my go-to serums because it helps to soften my skin without dryness or irritation. It's lightweight and it absorbs quickly and it hydrates and nourishes really well.

Hydrated Skin

This review is for Fleuri - Boost Serum.
I have super sensitive combination skin and this worked wonders on me.
The serum itself feels luxurious. It takes a while to absorb, but when it does it doesn't leave you looking greasy or shiny. Say goodbye to dry patches because this product hydrates unbelievably well.

A serum splurge

This serum by Fleuri is a splurge skincare item but it does feel lovely on the skin. I have combination sensitive skin and the dry, cold months leave my skin feeling so dry. This serum works well to hydrate gradually, leaving my skin feeling softer, supple and well hydrated. I like that the serum also works in hot humid weather. I used it while traveling in Asia and it doesn't feel heavy in hot and humid weather.


This serum is excellent.
Great ingredients to help provide nourishment for daily use.
A bit expensive, but has premium ingredients.
