Both are invisible chemical sunscreens made for makeup days. One is dewy, hydrating and $18. The other behaves more like a blurring primer.

Both SPF 50 formulas promise invisible protection without the chalky cast that makes people “forget” sunscreen. The real difference is texture: Beauty of Joseon Day Dew wears like dewy skincare, while Supergoop Unseen works like a smoothing makeup primer.
Buy Beauty of Joseon Day Dew if you want hydration, a fresh glow, stronger labeled water resistance and the lowest cost per ounce.
Buy Supergoop Unseen if you want a clear, silicone-rich gel that visibly blurs pores and grips makeup with a natural finish.
Neither is mineral. Both use avobenzone, homosalate, octisalate and octocrylene as active UV filters.
We checked each brand’s current Drug Facts and ingredient list, labeled water resistance, finish, makeup claims, testing disclosures, review volume and price per ounce. We also checked current FDA guidance on what 40-minute and 80-minute labels mean. We did not perform an in-house wear test, so brand-reported results are identified as such.
Day Dew is a fragrance-free, non-comedogenic chemical sunscreen developed for the U.S. market. Supporting ingredients include glycerin, niacinamide, panthenol, rice extract and sodium hyaluronate. Beauty of Joseon describes the finish as fresh and dewy and says it layers under makeup without pilling.
The strongest distinction is its 80-minute water-resistance label. The brand reports separate human SPF results of 94.7 in a Korean lab and 52 in a Spanish lab, while its U.S. label remains SPF 50. Its official page currently shows a 4.7 rating from 740 reviews, with 91 percent saying they would recommend it.
Fine Print: Broad-spectrum SPF 50 | 1.69 fl. oz. | $18 regular price | approximately $10.65 per ounce | dewy finish | no added fragrance or essential oils | non-comedogenic | 80-minute water resistance
Why this made the cut: It offers the better value and longer labeled water-resistance window while adding recognizable hydrating ingredients.

Unseen is a transparent, silicone-rich gel designed to double as a blurring makeup primer. Supergoop calls the finish natural rather than dewy, recommends it across skin types and describes the current SPF 50 formula as non-acnegenic and non-irritating.
Supergoop reports that its makeup-wear claim comes from a 33-woman clinical study comparing the product with foundation alone after eight hours. The brand also reports that 98 percent of 106 participants said it did not feel irritating after one application. Its official page currently shows approximately 5,700 reviews and a 4.7 rating.
The tradeoff is value and water resistance. The standard 1.7-ounce size is $38, approximately $22.35 per ounce, and its Drug Facts direct users to reapply after 40 minutes of swimming or sweating.
Fine Print: Broad-spectrum SPF 50 | 1.7 fl. oz. | $38 | approximately $22.35 per ounce | invisible natural finish | scentless | non-acnegenic | 40-minute water resistance
Why this made the cut: Its clear gel texture and documented makeup-primer positioning make it the more specialized choice for pore-blurring and foundation grip.

| Decision | Winner | Why |
|---|---|---|
| Lowest price | Day Dew | $18 versus $38 for nearly the same amount |
| Price per ounce | Day Dew | Approximately $10.65 versus $22.35 |
| Dry skin | Day Dew | Humectants plus a deliberately dewy finish |
| Oily skin | Unseen | A natural, non-greasy gel finish rather than added glow |
| Under makeup | Unseen | Built and clinically studied as a makeup-gripping primer |
| Swimming or sweating | Day Dew | 80-minute versus 40-minute labeled water resistance |
| No white cast | Tie | Both are transparent chemical formulas |
| Fragrance-sensitive routines | Tie | Day Dew is fragrance-free; Unseen is described as scentless |
Choose Day Dew if your skin leans normal or dry, you prefer a luminous base, or you want more sunscreen for your money. It is also the clearer choice for humid days, workouts and beach time because its label supports 80 minutes of water resistance.
Choose Unseen if your main complaint is sunscreen fighting with foundation. Its anhydrous, silicone-forward gel feels more like a dedicated primer and leaves less visible dew.
If your skin is highly reactive, patch-test either formula first. “Non-comedogenic” and “non-acnegenic” reduce concern, but neither term guarantees that every person will avoid irritation or breakouts.
Our verdict prioritizes labeled sun protection, real purchasing differences and cost rather than popularity alone. FDA guidance requires a water-resistant sunscreen to state whether testing supports 40 or 80 minutes, so that label difference carries more weight than vague claims such as “sweatproof.” Sunscreen still needs reapplication at least every two hours and immediately after towel drying.
