About Klairs
Klairs has been operating since 2010, which gives it a solid fifteen-year track record in sensitive-skin formulations.
Who Should Buy
Buy it if you have combination or oily skin that’s also dehydrated, you value fragrance-free formulas with real active content, and you want a gel cream that layers cleanly under sunscreen.
Texture
On use, the texture is where the formula earns its name. It’s genuinely a water-gel that breaks into a cool liquid on contact with skin, spreads easily with very little friction, and absorbs fully within about a minute. The cooling effect during application is noticeable and particularly welcome in summer or post-workout. Under sunscreen and makeup, it creates a smooth base that doesn’t pill, ball up, or interfere with foundation application — a failure point that trips up a lot of gel creams in this category.
Packaging
The 70ml jar is small for the price tier; at $28, the per-milliliter cost is higher than competitors like Pyunkang Yul Moisture Cream or Beauty of Joseon Dynasty Cream, both of which offer more volume for less money.
Common Praise
Over the first couple of weeks of daily use, the oil regulation effect becomes noticeable; skin stays matte-to-satin through the day rather than getting progressively shinier by afternoon, which is the usual pattern for dehydrated oily skin that’s been undertreated.
Common Complaints
Where does the formula run into limits? Dry skin won’t be happy with it as a standalone moisturizer. The weight is calibrated specifically for combination and oilier users, and dry skin will feel underserved after about an hour, reaching for a second layer or switching to a richer option. It’s also not fungal-acne safe despite the light feel — there’s sunflower oil and fatty alcohols lower on the list, and users with malassezia folliculitis should skip it.
Not ideal for
Skip it if you have dry skin, if price-per-milliliter is your primary metric, or if fungal acne is a concern.

The science.
The Science
This gel cream's ingredients follow recent research in combination-skin formulation. Green tea polyphenols — specifically EGCG (epigallocatechin gallate) — show antioxidant activity in skin and can regulate sebum in oily and acne-prone users. Using green tea leaf water instead of plain water as the base delivers these polyphenols at usable concentrations, though the exact concentration is undisclosed.
Phytosphingosine and caproyl sphingosine are ceramide precursors, not pre-formed ceramides. This distinction matters. Pre-formed ceramide deposition drives products like CeraVe and Epiduo and works well for acute barrier repair. Precursor-based approaches feed the skin's endogenous ceramide synthesis pathway and support long-term barrier resilience without occlusive delivery systems. Research on phytosphingosine is narrower than on pre-formed ceramides but shows effects on keratinocyte differentiation and antimicrobial peptide expression in published work.
Glyceryl glucoside has research regarding aquaporin-3 upregulation. Aquaporin-3 is the water channel protein that moves glycerol and water across keratinocyte membranes; upregulating it provides longer-lasting skin hydration than simple surface water binding. Cosmetic research shows glyceryl glucoside has measurable effects on skin hydration parameters over weeks of use. Trehalose has separate research on bioprotection and water binding during dehydration stress — pairing it with HA helps combination skin exposed to air conditioning, travel, or seasonal dryness. The panthenol and centella asiatica story is well-established and needs no repetition.
Dermatologist Perspective
Dermatologists treating combination or oily skin often recommend gel creams for daily moisturizing because they hydrate without adding occlusive load to sebum-rich areas. Board-certified dermatologists note that combination skin needs consistent barrier support even when oil production feels high — undertreated dehydration can worsen oil production over time. This formula's fragrance-free profile, ceramide precursor content, and light texture fit patients who need a moisturizer for both an oily t-zone and dehydrated cheeks. Patients with active fungal acne or malassezia folliculitis typically need oil-free alternatives, and patients with severely dry skin need a richer recommendation.
Where it fits in your routine.
Apply to damp skin after cleansing, toning, and applying serums. Use a spatula to scoop one to two small pearls, as hygiene matters with jar packaging, then spread evenly over the face and neck. Wait about 60 seconds for absorption before applying sunscreen or makeup. For very dehydrated skin, apply a hydrating toner or essence underneath to increase the humectant effect. Use twice daily for best oil-regulating results.
At $28 for 70ml, the per-milliliter price sits at the high end for K-beauty gel creams. Pyunkang Yul Moisture Cream and Beauty of Joseon Dynasty Cream provide more volume for less money, but neither uses a green tea water base or phytosphingosine. Klairs sells this only in the 70ml jar format; no larger value option exists. For combination-to-oily skin with dehydration concerns, the ingredient sophistication justifies the premium. Users who do not need this specific ingredient mix can find cheaper K-beauty gel creams that provide comparable hydration.
This works for combination and oily skin with dehydration, or those who find other Klairs moisturizers too thick. It suits anyone seeking a fragrance-free gel cream with barrier-precursor ingredients. It is also a good choice for summer-switch users moving from a heavy winter cream to a lighter one.
This works for dry skin needing a standalone daily moisturizer, fungal-acne-prone users, and anyone optimizing for price per milliliter. Skip if you prefer airless or tube packaging — the glass jar format uses a spatula for hygiene.

The backstory.
Dear, Klairs launched the Fundamental line in 2020 as a counterpart to the richer Supple Preparation range. The brand had been primarily recommended for dry and sensitive skin for a decade, but users with combination and oily complexions kept asking for a lighter option that shared the sensitive-skin DNA. This gel cream was the direct answer, built around green tea leaf water instead of plain water to signal the oil-regulating positioning.
About Dear, Klairs
Established Brand (5–20 years)Klairs launched in 2010 under parent company Wishtrend. The brand focuses on sensitive-skin and dehydrated-skin formulations. The Fundamental line targets combination and slightly oilier skin types that found the Supple Preparation line too thick.
Common myths.
Oily skin doesn't need moisturizer.
Oily skin loses water through the stratum corneum and often overproduces sebum when dehydrated. A lightweight moisturizer like this one reduces oil production over weeks by signaling that skin is hydrated.
Gel creams can't provide real barrier support.
Phytosphingosine and caproyl sphingosine in this formula support the skin's ceramide synthesis. This approach is more sustainable than depositing pre-formed ceramides on the surface and works in a gel texture without heavy occlusives.
FAQ.
How is this different from Klairs Midnight Blue Calming Cream?
Midnight Blue is a niche repair cream that uses guaiazulene to soothe post-irritation and active flare-ups. Fundamental Water Gel Cream is a daily moisturizer for combination and oily skin using green tea water and phytosphingosine. Different jobs, different formulas.
Can dry skin use this gel cream?
Technically yes, but dry skin needs a thicker formula for lasting comfort. Dry skin can use this under a heavier cream or in summer for a lighter finish. For daily use on dry skin, Klairs' Supple Preparation lotion or Rich Moist Soothing Cream work better.
Will this clog my pores?
This formula rarely causes purely comedonal acne for most users because it has minimal oil and mostly synthetic esters. It is not fungal-acne safe because of the sunflower oil and fatty alcohols. If you have malassezia-driven breakouts, check the fungal-acne considerations first.
Is this fragrance-free?
Yes — it has no added fragrance. The mild natural scent comes from the green tea leaf water and botanical extracts and fades within minutes of application.
Does it work under sunscreen and makeup?
Yes — this is one of its strengths. The gel cream absorbs fully in about a minute. It creates a smooth base that layers under chemical sunscreens and most foundations without pilling.
How long does the 70ml jar last?
One to two pearls per application, used twice daily on the face, lasts about two to three months. Using less can extend the jar's life.
