'Holy Grail serum': This glow-boosting, anti-aging balm from CosRx is 50% off

Down to $14, this skin soother harnesses the healing powers of bee propolis to leave your face dewy and plump.

"Protect me from what I want," artist Jenny Holzer famously said. It's a sentiment I, like many women, often ignore when what I want is to shell out more money than I should in the quest for amazing skin. (I know, vanity/pride is a deadly sin — I'm working on it). As a beauty editor, I'm always looking for the latest, greatest skin care that will bring bounciness and brightness to my 51-year-old visage. To that end, I drop serious cash on quality products, but, on occasion, the beauty angels provide a more affordable solution for my aging woes. Case in point: Today, one of my favorites, CosRx Propolis Ampoule Glow Boosting Serum, is 50% off — down to a mere $14.

This epic skin hydrator from beloved K-beauty brand CosRx promises to lend even the dullest skin a radiant glow.

Why is this a good deal? 💰

CosRx is a trusted K-beauty brand known for effective skin-care products made with potent, high-quality ingredients. In other words, you know you're getting good stuff here, and this is mere pennies above the lowest price we've ever seen this.

Why do I need this? 🤔

As we age, our skin can become dull and lose its luster, creating a sallow appearance that can make us look older overall. This serum is excellent for deeply hydrating skin and giving your face the healthy-looking sheen you had when you were young. In addition, if you're experiencing irritation, this highly concentrated propolis formula can help soothe skin and reduce redness.

Like CosRx's most famous product — Snail Mucin Essence (check out my full review) — this rich, nonsticky, fast-absorbing elixir is highly concentrated with a pure extraction of its hero ingredient, propolis. It's a resin-like substance made by bees which the insects then use to make beehives. In clinical studies, propolis has been shown to have antibacterial, anti-inflammatory properties and can aid in helping skin heal. CosRx Propolis Ampoule Glow Boosting Serum contains 73.5% propolis extract, the highest concentration I've seen in any beauty product.

What reviewers say 💬

Customers say CosRx Propolis Ampoule Glow Boosting Serum works for even sensitive skin, that it absorbs fast without pilling and makes their skin appear moisturized, dewy and plump.

Pros 👍

"I love CosRx," raved one five-star reviewer. "This serum makes my skin so plump, radiant and soft! A little goes a long way. It has no scent, it's very moisturizing, it melts into your skin and is easy to apply."

"Holy Grail serum," exclaimed another. "I have reactive skin that is prone to irritation, and I have been buying this serum on repeat for the past two years — it is a must-have for glowy, healthy-looking skin for me! It absorbs into skin without being sticky, keeps my skin hydrated throughout the day and wears great under makeup and other moisturizers."

Other fans have become devotees: "Already on my second bottle! My skin loves this serum so much. I'm 42 and my skin is dryer than it used to be when I was younger. I love the dropper applicator, it's the perfect dose for daily use. It's lightweight, has good absorption and doesn't cause any pilling of foundation or skin tint you may apply over it. Totally recommend."

Cons 👎

Some CosRx fans say they still prefer the brand's famous snail serum, and others with oily skin said this serum caused breakouts.

"Meh," said this buyer. "Didn't really see that much of a difference compared to their snail mucin."

"Nice glow," admitted another, "but it broke me out, so I had to return it."

This CosRx serum has fewer than 10 ingredients (score) and more than 2,000 five-star reviews (double score).
