The basics
About this product
Do not assume that an older Korean SPF50+ PA++++ package and this listing use the same filters simply because the Hyalu-Cica name looks familiar.
Inside the formula
Ingredients, explained
Formula focus
The checked listing identifies avobenzone 2.7%, homosalate 13.6%, octisalate 4.5% and octocrylene 9% as active ingredients.
It also lists panthenol, centella extract and several forms of hyaluronic acid among the other ingredients. SKIN1004 describes a lightweight, serum-like finish and hydration benefits. Those are attributed brand descriptions, not measurements of greasiness, white cast or wear on different skin tones. The label's UV-filter information is more reliable for identifying this version than applying remembered facts about a previous formula.

When to consider it
- The first decision is which market version you are buying.
What to weigh up
- For repurchase, compare the full name, active filters and protection label with the bottle you already own.
More buying tradeoffs
For repurchase, compare the full name, active filters and protection label with the bottle you already own. If those differ, treat the listing as a different formula until you confirm otherwise.
The checked store offers one 50ml bottle and a two-bottle option. Compare total milliliters and the selected sale price before deciding on value. Someone choosing mainly for a matte finish should not treat the brand's lightweight wording as a verified matte-wear result.
This is a buying interpretation, not a personal skin assessment. Individual reactions and the products used alongside it can change the experience.
In your routine
How to use it
Use the directions and reapplication instructions printed on the exact sunscreen package you purchase. A product called sun serum is still a sunscreen, not a few-drop treatment serum to mix into another product. This article does not replace the label with an invented application amount, water-resistance duration or guarantee for swimming and heavy sweating.
Follow the directions on the version you buy.
Sizes, price & availability
SKIN1004 Hyalu-Cica Water-Fit Sun Serum UV: 50ml; a 50ml x 2 option is listed separately.
USD 16.15 sale / USD 19 regular for the 50ml option on the checked official listing. This is a dated listing reference, not a permanent offer or a Korean shelf price. Shipping, tax and destination eligibility must be checked separately.
Select the exact size and market before comparing cost. A dollar price observed in one storefront does not prove that sales are limited to that country.
Check the official product listing ↗A few common questions
Is this necessarily the same formula sold in Korea?
No. The checked UV listing has its own active-filter label; inspect the exact regional pack.
Does serum mean I use only a few drops?
No. Follow the sunscreen label, not the application amount for a treatment serum.
Has white cast been tested by this site?
No. The no-white-cast description comes from SKIN1004 and is not a skin-tone-specific test here.
