Haruharu Airyfit is a Korean daily-SPF alternative to investigate after SKIN1004, not the same sunscreen label.
A public skincare question asks for an alternative to SKIN1004 Hyalu-Cica Water-Fit Sun Serum UV after the poster’s personal experience with the product. Replies named haruharu wonder Black Rice Moisture Airyfit Daily Sunscreen. Both pages describe a daily face-SPF step, but their regional labels, visible filter disclosure, finish language and directions differ. This page is a source-linked job comparison, not a formula dupe, equal-protection claim or diagnosis.
Why this exact pair is worth answering
A public r/koreanskincare replacement question was checked on 9 September 2026. The post had 68 likes and 97 comments at the check. A reply named haruharu wonder Black Rice Moisture Airyfit Daily Sunscreen, and the original poster said they would look into it. That is a concrete query-and-candidate signal, not search volume, product testing, safety evidence or sales proof.
The question describes one person’s routine experience and asks for recommendations. We do not diagnose the experience, convert it into a product-safety conclusion or assume that another sunscreen will solve it. The useful answer is narrower: compare the named candidate’s current label and routine brief with the original product.
What SKIN1004’s official US page publishes
| Product | Hyalu-Cica Water-Fit Sun Serum UV |
|---|---|
| Routine job | Hydrating daily SPF 50 sun serum for the face and other exposed areas |
| Format and size | Lightweight, serum-like sunscreen; 50 ml on the checked official US page |
| Visible US active filters | Avobenzone 2.7%, Homosalate 13.6%, Octisalate 4.5% and Octocrylene 9% |
| Other published formula cues | Panthenol, Centella, hyaluronates and rice, oat and soy extracts appear in the visible inactive list; the brand describes hydration and a fresh, no-white-cast finish |
| Directions checked | Use as the last step of basic skincare and apply evenly to the face, neck, arms and legs; follow the current product label |
| US price snapshot | US$17.10 sale display / US$19 regular display at the check; stock and price are unstable |
The four percentages above are the active ingredients visible on the checked US page. They describe that market’s label surface. Ingredient lists and packaging can change, so the current product page and package remain the final check.

| Product | Black Rice Moisture Airyfit Daily Sunscreen SPF50+ / PA++++ · Unscented |

| Visible label and finish cues | SPF50+ / PA++++, unscented, velvet finish, smooth and semi-matte, non-greasy and zero-white-cast language on the official page |
| Published formula cues | Black-rice-infused oil, niacinamide, adenosine, propanediol, Houttuynia Cordata extract and eco-ceramide are named in the key-ingredient summary; the page also states fragrance-free, alcohol-free and paraben-free |

The Haruharu page’s visible product summary did not show a comparable active-filter percentage table when checked. That does not mean the product has no filters; it means this comparison records the disclosure that was visible on each official page instead of filling in missing percentages.

Same daily-SPF step, different label
Both products can answer the broad “daily face sunscreen” job. SKIN1004’s page calls its product SPF 50 and shows US active percentages. Haruharu’s US page calls its product SPF50+ / PA++++ and foregrounds an unscented, airy, semi-matte wear brief. SPF numbers from different label systems do not prove identical protection in use, and similar “no white cast” or lightweight language does not prove the same finish on every person.
The shared routine step is enough to investigate Haruharu as a candidate. It is not enough to call it the same formula, a guaranteed answer to an individual skin response or a universally safer choice. Read the market-specific label and use the product according to its current directions.
Side by side
| SKIN1004 Hyalu-Cica Water-Fit | haruharu Airyfit Unscented | |
|---|---|---|
| Broad job | Hydrating daily SPF step | Daily face SPF step with a lightweight, semi-matte brief |
| Displayed label | SPF 50 on the checked US page | SPF50+ / PA++++ on the checked US page |
| Visible filter disclosure | Avobenzone, homosalate, octisalate and octocrylene percentages shown | No comparable filter-percentage table visible in the checked product summary |
| Finish wording | Fresh, serum-like and no-white-cast language | Airy, smooth, velvet, semi-matte, non-greasy and zero-white-cast language |
| Directions | Last step; face, neck, arms and legs | After moisturizer; two finger lengths; wait 30–40 seconds before makeup; reapply every two hours |
| Size and checked US price | 50 ml / US$17.10 sale, US$19 regular display | 50 ml / US$22 display |
| Verdict here | Same broad daily-SPF routine job; different labels, visible disclosures, finish briefs and price snapshots. Not an equal-protection or formula-equivalence claim. | |
Choose by the reason you are switching
- You want another Korean daily SPF candidate: Haruharu is the direct named candidate from the public question, with a 50 ml SPF product and an official US purchase path at the check.
- You want the same US active-filter label: Haruharu does not qualify from the evidence visible here. Its page did not expose the same percentage table.
- You want a similar wear brief: both brands use lightweight and no-white-cast language, while Haruharu adds semi-matte and velvet cues. Those are brand descriptions, not a personal wear guarantee.
- You want the lower displayed price: SKIN1004’s checked sale display was lower, but its stock and promotion were unstable. Do not make a universal savings claim from one dated snapshot.
- You are trying to interpret bumps, irritation or another skin concern: follow the current label and ask a qualified clinician about health questions. This page does not diagnose or promise a treatment outcome.

Keep the routine step and the formula question separate before calling anything a dupe:

- EltaMD UV Clear vs Korean sunscreen options — a zinc-oxide and octinoxate comparison, not a match for either product here.
