Tranexamic acid has an unusual résumé for a beauty ingredient. It was developed in the 1960s to help blood clot, and it is still given in operating theatres and to people with heavy menstrual bleeding. Its second career began when doctors treating patients for other reasons noticed their melasma fading, which sent researchers looking at how the molecule interferes with the signals that switch pigment cells on. By the early 2020s it had moved from prescription tablets to over-the-counter serums, and in spring 2022 LOOPS put it into a hydrogel mask called Hyper Smooth. That journey from operating room to self-care night is what makes this product worth a proper look.
The formula is smarter than its cheerful packaging suggests. Rather than relying on one brightener, it stacks three that interrupt pigment at different points. Niacinamide, which appears fourth on the ingredient list ahead of all the gums and preservatives, reduces the transfer of finished pigment from melanocytes to the surrounding skin cells. Alpha-arbutin sits further down and works earlier in the chain by slowing tyrosinase, the enzyme that builds melanin. Tranexamic acid, close behind, reduces some of the inflammatory and hormonal signals that ask melanocytes to produce more pigment in the first place. A small amount of ascorbic acid and a trace of lactic acid round out the brightening group, alongside phytic acid as a chelator.
Then comes the herbal section, which reads like a page from a traditional Korean pharmacopoeia: rehmannia root, licorice root, ophiopogon, phellodendron bark, white peony root, anemarrhena and angelica. Licorice has the most respectable evidence among them for soothing and gentle brightening. The others contribute antioxidant and calming claims with thinner support, and their position near the end of the list means they are best considered seasoning. A fruit-extract blend of lime, orange, lemon, apple and grape follows, and a blue colourant gives the mask its signature tint.
The hydrogel itself is the point of the format. It is made from carob gum, Irish moss powder and glucomannan, a solid gel that holds its watery essence against the skin instead of letting it drip down the neck the way a cotton sheet does. Reviewers single this out repeatedly: the mask grips, stays put and feels cool. The textured inner side is meant to face the skin. After ten minutes you peel it off and tap the leftover essence in.
The immediate result is real and pleasant. Skin looks plumper, smoother and more luminous because glycerin, butylene glycol and hydroxyethyl urea have flooded the outer layer with water. This is the effect most Target reviewers describe when they talk about a glow, and with a 4.7-star average from around 140 ratings, it clearly satisfies. A smaller group of reviewers report that regular weekly use helped their tone look more even over time, which is plausible given the actives, though it is impossible to separate the mask's contribution from whatever else they were using.
That is the central limitation. Pigment does not respond to single sessions. The clinical work on niacinamide with tranexamic acid used a leave-on cream twice a day for eight weeks, alongside daily sunscreen. A ten-minute mask once a week, with the essence pressed in afterwards, delivers a fraction of that exposure. Hyper Smooth can contribute to a fading routine, but it cannot replace a daily brightening serum, and it certainly cannot replace sun protection, without which no topical keeps up with fresh UV-triggered pigment.
The second limitation is tolerance. The formula is fragrance-free and avoids essential oils, which is good. But a minority of Target reviewers with sensitive skin describe burning, itching, redness or breakouts. The likely suspects are the lactic acid and citrus fruit extracts, perhaps combined with the occlusion of the gel increasing penetration. If your skin is reactive, rosacea-prone or currently compromised, patch-test on the jawline and remove the mask at the first sting.
LOOPS' product page lists two slightly different ingredient decks, one with hydroxyacetophenone and tamarind seed gum and a reordered herbal section. The core actives are the same in both, but the brand does not say which version is in which carton, which is a small transparency gap.
On value, the five-pack costs $30, or $6 a mask, and singles sell at Target for about the same. That is reasonable for a well-made hydrogel with a credible active stack, though it adds up if you mask weekly year-round. As a treat that makes skin look its best before an event while nudging a longer spot-fading plan along, it earns its place. As a stand-alone answer to hyperpigmentation, it is too brief an encounter to deliver what the box implies.
LOOPS is a young brand, founded in 2020, with no published testing of its own masks. Its approach here is sensible: well-chosen actives, no fragrance and a format that genuinely improves on the classic sheet mask. Hyper Smooth suits normal, combination and oily skin types that want an instant glow with a side of long-game brightening. Sensitive skin should approach carefully, and anyone hoping for dramatic fading from five masks will be disappointed.
