💡 Pro Tip: Supergoop Unseen Sunscreen SPF 40 is rated for broad spectrum UVA/UVB protection. Regardless of activity, the FDA recommends reapplying any sunscreen every 2 hours when outdoors, and immediately after swimming or heavy sweating. Applying less than the recommended 2mg/cm² can significantly reduce the effective SPF — sometimes to less than half.
⚠ Water Resistance Note: Supergoop Unseen Sunscreen is water-resistant for 40 minutes. After swimming or heavy sweating, reapply immediately even if it has not been 2 hours. The formula works as a makeup primer and should be applied as the last step in your skincare routine but before makeup.

Supergoop’s Unseen Sunscreen SPF 50 became a real cult favorite, and honestly easily understand the reason. This truly deserves the name, because it genuinely disappears on the face without a trace weight or smell, while it gives broad protection SPF 50 against sun rays, without leaving oily traces. It works for all skin types, tones and daily routine, because the product simply blends in the skin without any color shade visible.

More than sun protection, this has a bonus: it works really well as a base for makeup. Many users found it helpful for fixing the makeup during the whole day, and studies show that it indeed improves the clarity of the skin. At Sephora you find whether mineral or chemical version.

Supergoop Unseen SPF 50 — Invisible Sunscreen and Makeup Base

Notably, some favor the mineral form for makeup, because it gives the makeup a bit more staying power.

The sunscreen started with SPF 40 and soon blew up on social media, when beauty fans could not stop praising its lightweight and genuinely invisible feeling. The company improved it to SPF 50 with a new formula, and now it is essential for those that want sunscreen that looks elegant for the day. In United Kingdom, Selfridges also sell it.

What most stands out about texture is the smooth and fast application. It has no smell, no glue, no gloss, no pull, none of that stressful rolling, and certainly no white cast. Many other sunscreens that promise invisibility commonly leave chalky or ashy finish, but this genuinely does not.

It feels like a silky base, giving your skin a smooth and fancy touch. The formula carries ingredients like red algae, that calm the skin and also protect against blue light.

One spot to recall: it relies on silicone. That can be a problem, because some folks find silicone wierd on the skin, it sits up instead of soaking in. If you did not adjust to sunscreens with silicone, start with the little tube to test, before buying the big one.

Also there are test sets with Unseen and some other products in little sizes.

About price, this deserves to consider in your choice. The version for face costs around thirty-eight dollars for 1.7 ounces, while the new physical version runs forty-two dollars for 3.5 ounces. On the other hand, Trader Joe’s launched something quite alike for almost ten dollars in the same 1.7-ounce size, and many claim that they are swappable.

The results in real life proved themselves good. It held up during hikes in Acadia National Park, ocean dips in Hawaii and biking routes threw New York. For places like camping or hiking, the no-scent quality genuinely helps, and the silky base-like finish means that you do not add smell to the nature.

Some users noted a bit oily feeling, and occasionally it causes rolling when mixed withcertain skin products or makeup.
