There are some sunscreen products that become popular because of clever marketing. Then there are products that become popular because people genuinely enjoy using them every morning.
The SKIN1004 Madagascar Centella Hyalu Cica Water Fit Sun Serum falls into the second category. It has become one of the most recognizably Korean sunscreens for people who want strong daily UV protection without the heavy feeling that often comes with traditional sunscreen.
It is designed to feel more like a lightweight skincare serum than a conventional sunscreen. The result is a dewy finish, comfortable hydration, and no obvious white cast. It is also currently listed by YesStyle as its 2025 Favorite Sunscreen, reflecting its popularity among the retailer’s community. (YesStyle)
But popularity does not automatically make a sunscreen worth buying. The real question is whether the formula delivers what you actually need from a daily SPF.
What Is the SKIN1004 Hyalu Cica Sun Serum?
The Hyalu Cica Water Fit Sun Serum is a chemical sunscreen offering SPF 50+ and PA++++ protection. It combines UV filters with hydrating and soothing ingredients, including centella asiatica and hyaluronic acid. (SKIN1004)
The idea is simple. Instead of treating sunscreen as a separate, heavy final step, SKIN1004 created something that feels closer to a moisturizing serum.
That makes sense for anyone who has avoided sunscreen because they dislike greasy textures, white residue, or the feeling of having another layer sitting on their face.
The Texture Is the Main Attraction in this Sunscreen
The first thing you notice about this sunscreen is the texture.
It has a light, fluid consistency that spreads easily across the skin. SKIN1004 describes it as a serum like formula that absorbs quickly with minimal stickiness and a dewy finish. (SKIN1004)
This is where the product stands apart from many traditional sunscreens.
It does not try to create a matte, powdery finish. Instead, it leaves the skin looking fresh and naturally luminous.
For normal or dry skin, that glow can make the complexion look healthier. However, if you strongly prefer a completely matte finish, the dewy texture may not be your favourite.
What Does Hyalu Cica Actually Mean?
The name sounds complicated, but the concept is relatively simple.
“Hyalu” refers to hyaluronic acid, a well known humectant that helps attract and retain water within the skin.
“Cica” refers to Centella Asiatica, an ingredient widely used in Korean skincare for its soothing and skin supporting properties.
Together, they form the core of the product’s skincare focused approach.
The current formula also contains panthenol and several botanical extracts, adding further hydration and antioxidant support. (SKIN1004)
The Key Ingredients of This Sunscreen
Centella Asiatica
Centella asiatica is one of SKIN1004’s signature ingredients.
The brand sources its centella from Madagascar and uses it throughout its product range. In this sunscreen, it helps support a soothing and comfortable skin feel alongside the UV protection.
Hyaluronic Acid
The formula uses several forms of hyaluronic acid, including sodium hyaluronate and hydrolyzed hyaluronic acid. These ingredients help support hydration and contribute to the plump, fresh finish associated with the product. (SKIN1004)
Panthenol
Panthenol is another useful addition because it supports hydration and helps maintain skin comfort.
This is particularly relevant when sunscreen is being used every day. A product that protects the skin while also keeping it comfortable is much easier to use consistently.
Botanical Extracts
The formula also includes green tea, broccoli sprout, wheat sprout, arugula, alfalfa, and camellia extracts. These provide additional antioxidant and skin conditioning properties. (SKIN1004)
The result is a sunscreen that does more than simply sit on top of the skin.
Does It Leave a White Cast for a Sunscreen?
One of the biggest selling points is the lack of an obvious white cast.
The lightweight formula is designed to blend into the skin without leaving the chalky appearance associated with some mineral sunscreens. YesStyle also highlights its clear finish and compatibility across different skin tones. (YesStyle)
This makes it particularly appealing if you have previously avoided sunscreen because of how it looks after application.
Who Is This Sunscreen Best For?
The original formulation is particularly appealing for normal, dry, and sensitive skin, although the brand also lists combination skin among suitable skin types. (SKIN1004)
It may work especially well if you want:
- Lightweight daily sun protection
- hydrated, dewy finish
- No obvious white cast
- A sunscreen that layers comfortably with skincare
- formula that feels more like skincare than traditional SPF
- Additional soothing and hydrating ingredients
Those with very oily skin may prefer something with a more matte finish, particularly during hot or humid weather.
How to Use It
Sunscreen should be the final step of your morning skincare routine.
Apply it evenly across the face, neck, and other exposed areas before heading outside. The brand recommends applying and re-applying it to areas exposed to UV rays, including the face, neck, arms, and legs. (SKIN1004)
Most importantly, use enough sunscreen to achieve the protection indicated on the label. Applying too little can significantly reduce the level of protection you actually receive.
Reapplication is also important, particularly when spending extended periods outdoors or after sweating and swimming. YesStyle recommends reapplying every two hours, or sooner in those situations. (YesStyle)
Can You Wear This Sunscreen Under Makeup?
Yes.
The serum like texture makes it a natural fit underneath makeup. Its lightweight finish means you do not have to deal with the heavy layering that can make some sunscreens difficult to wear during the day.
The dewy finish can also work nicely as a base if you prefer a more luminous complexion.
Is the Dewy Finish Too Much?
This will depend entirely on your skin type and personal preference.
For dry or normal skin, the glow can be one of the best parts of the product. It gives the complexion a fresh, hydrated appearance without needing a separate glow product.
For oily skin, however, that same finish may become more noticeable as the day progresses.
This is not necessarily a flaw. It simply means the sunscreen has a specific aesthetic. If you love natural radiance, it is a strong match. If you want your skin completely matte, you may need a different formula.
What Makes It Different From Traditional Sunscreen?
The biggest difference is the experience.
Traditional sunscreen often feels like sunscreen. You know you are wearing it.
The SKIN1004 formula tries to blur that distinction. Its lightweight texture, hydrating ingredients, and dewy finish make it feel much closer to a serum or moisturizer.
That matters because the best sunscreen is ultimately one you will use consistently.
A technically excellent sunscreen that you hate wearing is unlikely to become part of your daily routine.
The Verdict
The SKIN1004 Madagascar Centella Hyalu Cica Water Fit Sun Serum makes a strong case for why Korean sunscreens have become so popular.
It combines SPF 50+ and PA++++ protection with a lightweight texture, hydration, centella, hyaluronic acid, and a natural dewy finish. (SKIN1004)
Its biggest strength is not that it reinvented sunscreen. Instead, it makes daily sunscreen feel easier and more enjoyable to use.
For normal, dry, or combination skin that enjoys a hydrated finish, it is an especially appealing option. If you prefer completely matte sunscreen or have very oily skin, the finish may be less convincing.
The Editor’s Thoughts Moving Forward
Sunscreen has changed.
It used to be treated as the final chore in a skincare routine. Now, the best formulas are becoming products people genuinely look forward to applying.
That is what makes the SKIN1004 Hyalu Cica Water Fit Sun Serum interesting. It understands that protection is only useful when people actually want to wear it every day.
The lightweight texture, hydrating ingredients, and fresh finish make the product feel less like a compromise and more like part of the skincare routine itself.
And perhaps that is the real reason it has become so popular.
Great sunscreen does not need to announce itself. It simply needs to make protecting your skin feel effortless.
