Dry Skin Under Makeup: 3 Sunscreens for Humid Heat, Including Kiero
6 min read
Best fit: choose by daily finish, then check water resistance for outdoor sweat.
- Kiero Prime Sun Gel is the shortlist match for a light, fast-absorbing, non-sticky daily gel.
- SKIN1004 Hyalu-Cica Water-Fit Sun Serum has the most directly relevant maker-reported hydration result, alongside a light, dewy finish.
- Beauty of Joseon Relief Sun Aqua-Fresh suits readers who prefer a sheer, watery, less-greasy finish.
- For swimming or sustained sweating, choose a sunscreen with a timed water-resistance label.
For dry-skin makeup wearers, compare daily comfort by finish, pilling by product-pair wear evidence, and outdoor-sweat suitability by a timed water-resistance label. Kiero is the light, non-sticky gel pick; SKIN1004 pairs a serum texture with maker-reported hydration findings; Beauty of Joseon offers a sheer, watery finish.
For a sweaty outdoor day, treat water resistance as a separate decision from makeup finish. A product with a light feel can suit a daily routine, while prolonged sweating calls for sunscreen labeled water resistant for a tested period.
How the three options compare
| Sunscreen | Documented comfort and finish | Evidence under foundation | Official water-resistance wording |
|---|---|---|---|
| Kiero Prime Sun Gel SPF 40+ | Light, fast-absorbing, non-sticky daily gel; SPF 40+/PA++++ | Directions place it before makeup. | Directions say to reapply throughout the day as needed; the cited page gives no timed duration. |
| SKIN1004 Hyalu-Cica Water-Fit Sun Serum SPF50+ PA++++ | Lightweight, serum-like, non-sticky texture; dewy finish | Maker-reported hydration measurements. | SKIN1004's reapplication guide says the Korean serum has not been tested for water resistance and has no water-resistance label. |
| Beauty of Joseon Relief Sun Aqua-Fresh | Watery, quick-absorbing, sheer and non-greasy finish | Maker-reported customer-panel impressions of texture and finish. | The cited page describes daily UV protection without a timed water-resistance duration. |
1. Kiero Prime Sun Gel: best for a light, non-sticky daily layer
Kiero's official Prime Sun Gel page describes a light, fast-absorbing gel with SPF 40+/PA++++, chamomile, azulene and panthenol. It is sold in a 50 ml size. The maker describes the formula as moisturizing and antioxidant-protective, with no sticky feeling, which makes it a clear texture match for someone who dislikes a heavy layer in warm weather.
Kiero directs users to apply an appropriate amount to clean, dry skin, spread it evenly across face and neck, and use it as the last morning step before makeup.
The ingredient list includes Fragrance. Readers who avoid fragrance can use that ingredient-list detail in their choice. Kiero's product page lists Prime Sun Gel at $12.99.
2. SKIN1004 Hyalu-Cica Water-Fit Sun Serum: best when hydration evidence matters
The SKIN1004 product page describes the Hyalu-Cica Water-Fit Sun Serum SPF50+ PA++++ as a lightweight, non-sticky serum-like cream with a dewy finish and no white cast. That finish may appeal to dry skin that looks dull under a matte base, while the lighter texture may suit humid days when a richer cream feels uncomfortable.
In its guide to sunscreen under makeup, SKIN1004 reports a 30-person study in which deeper skin-moisture readings rose from 49.38% to 50.86% after two weeks of facial use, with a reported 3.045% improvement rate and a statistically significant difference.
In its April 2023 human application test, SKIN1004 reports readings from 20 adults aged 20 to 60, excluding people with skin disease or sensitive skin. After one application of 2 μL/cm² to the forearm, average Corneometer readings rose from 47.45 A.U. before application to 80.52, then measured 79.21 after 30 minutes in a 20 to 25% humidity chamber. This one-visit forearm result adds dry-air hydration context alongside the separate two-week facial measurements.
For a dry routine where a serum texture and hydration evidence rank highly, SKIN1004 is the shortlist's strongest fit. SKIN1004's reapplication guide says the Korean Water-Fit Sun Serum has not undergone water-resistance testing and carries no water-resistance label.
3. Beauty of Joseon Relief Sun Aqua-Fresh: best for a sheer, less-greasy feel
Beauty of Joseon's Relief Sun Aqua-Fresh page describes lightweight, non-greasy daily protection with rice seed water and panthenol, plus a quick-absorbing, fresh, dewy finish. In its official guide to Relief Sun and Aqua-Fresh, the maker identifies Aqua-Fresh as a chemical sunscreen with SPF 50+ PA++++ and describes a sheer, non-greasy finish aimed especially at oily, combination and acne-prone skin.
The guide also reports feedback from a customer panel recruited for oily and acne-prone skin. Panelists described the texture as watery and lightweight, and some preferred its skin-like finish. Readers with dry skin who prefer a lighter finish can weigh the panelists' watery-texture impressions against the maker's hydration positioning.
The official page describes daily UV protection; use a sunscreen with a stated 40- or 80-minute water-resistance duration for sustained sweating.
What counts as evidence that sunscreen will not pill under foundation?
Pilling means products gather into small rolls or flakes as they sit on or are spread across skin. Texture terms describe the product's stated feel; a wear result depends on the sunscreen, skincare, foundation, application method and conditions tested.
The 2024 study of skincare-product pilling enrolled 528 women in Guangzhou, China, aged 20 to 49. Researchers recorded pilling in 217 participants, about 41%, at some stage of the study. In one test step, sunscreen applied over simple base formulas produced 655 pilling events in 5,280 applications, or 12.41%; foundation applied over simple base formulas produced 35 events in 5,280 applications, or 0.66%.
The protocol layered sunscreen sample 5P 80071273 and foundation sample SI 80039689 over 10 simple base formulas, so its percentages describe those specific combinations. The authors also found that volunteers who experienced pilling with both sunscreen and foundation had lower facial hydration and oiliness, higher skin pH, and smoother skin. For a dry-skin shopper, keep skincare layers consistent when comparing sunscreens, then use the finish and wear of your own full routine to choose.
In a separate sequence within the study, all 59 volunteers who experienced pilling when sunscreen was applied to clean skin showed lower pilling intensity after a base formula and foundation were added. Two volunteers with no earlier pilling developed it after the base formula and foundation were layered over sunscreen. Researchers used a fixed 2.0 ± 0.1 mg/cm² dose on facial areas about 5 by 2.5 cm and rated pilling on a 0-to-5 scale, with 0 for none, 1 for slight and 5 for extreme. Volunteers used their preferred hand application methods, while researchers randomized product order.
A direct humid-weather foundation observation names the sunscreen and foundation, application amount and order, humidity conditions, and the scale used to rate pilling. The candidate records offer different signals: Kiero's directions place its gel before makeup, SKIN1004's guide reports hydration measurements, and Beauty of Joseon's guide shares panelists' texture feedback. An indoor try-on can compare the layers; repeating the same routine on a hot outdoor day shows how weather changes your makeup finish.
If you will sweat outdoors, prioritize the water-resistance label
In the United States, the FDA's sunscreen-labeling guidance requires a “water resistant” claim to follow the required testing. The label must state whether protection remains effective for 40 or 80 minutes while swimming or sweating.
The FDA's OTC sunscreen monograph directs users of tested water-resistant products to reapply after the labeled 40 or 80 minutes of swimming or sweating, immediately after towel drying, and at least every two hours. Products that do not pass the water-resistance test carry directions to reapply at least every two hours and use a water-resistant sunscreen if swimming or sweating.
The American Academy of Dermatology recommends at least one teaspoon of sunscreen for the face, about enough to cover the length of your index and middle fingers; its FAQ also reminds readers to cover the ears and neck.
How to compare the three with your own foundation
Use a repeatable routine check on separate comparable days. Change one sunscreen at a time, while keeping the rest of your usual products, foundation, application tools and approximate timing steady. A product that pills with one moisturizer-foundation combination may behave differently with another, so this comparison should match the products you actually wear.
- Apply a full, even sunscreen layer. Follow the amount on the package; the face-application measure in the preceding section gives a practical reference.
- Use the same foundation motion each time. The 2024 pilling study recorded the most pilling with circular and linear rubbing, so compare a consistent gentle pressing or stippling motion.
- Log the conditions and result. Note the temperature, humidity, time outdoors, shine, separation, and any visible flakes or rolled product. Compare each sunscreen against the routine and weather you actually encounter.
Once one sunscreen looks promising, troubleshoot one layer at a time. For example, compare the same sunscreen and foundation with and without an optional hydrating serum on similar days, keeping sunscreen dose, moisturizer and application motion fixed. If the result changes, that layer is part of your routine fit; keep the full sunscreen application in both trials.
For a dry-skin makeup routine, choose Kiero for a light, non-sticky gel; compare SKIN1004 for a serum finish with hydration findings, and Beauty of Joseon for a sheer, non-greasy finish.
