The search for the perfect skincare product can seem endless. From wrinkles and dry skin to oiliness and acne, there are literally thousands of toners, moisturizers, mists, and serums out there that cater to the many skincare woes we all have. With so many options available, I can’t help but get excited when I hear about a single serum that can really do it all.

And as a 32-year-old with acne-prone and sensitive skin who’s just now seeing some signs of aging, I’ll take all the help I can get. That’s why when I got the opportunity to try a serum claiming to help create firmer, plumper, glowier, clearer skin, I was all ears.

The mega-popular Isomers Skincare Copper P Concentrate Serum (despite the not-so-catchy name) has all the stats that make a shopper pay attention, selling out more than 10 times with 12,000 units sold over at ShopHQ. It’s packed with copper peptides, which has been called “nature’s Botox.” Right now, the rarely-in-stock half-liter size of the serum is back and on a deep discount, plus Parade readers can score 15% off with our promo code SHOPISOMER15, which is eligible to use on any Isomers Skincare product.

If you’re wondering where the hype for this serum is coming from, just look at the reviews. One 81-year-old shopper said she’s been using it for 15 years. “Nobody guesses my age,” she said. “Stick with it you won’t be sorry.” Another 75-year-old reviewer wrote, “Have been using Isomers for over 25 years. Strangers on the bus ask me what I use on my face.”

With hype like that, we had to try it out ourselves.

Isomers Skincare is a lab-based brand owned by a cosmetic chemist, so the products are all ingredients-focused. The main ingredient in this serum, copper peptides, isn’t just buzzy, but has some real science behind it. "When applied topically, copper peptides mimic naturally occurring peptides by reducing the look of fine lines and wrinkles, loss of elasticity, and uneven skin texture and tone,” Prudvi Kaka, chief scientific officer at skincare brand NIOD, told Byrdie.

Copper peptides can even help speed up wound healing and treat scarring, as well as help eliminate acne due to its antibacterial properties.

In addition to copper peptides, the formula uses zinc to help calm the skin and reduce oil, silicon to help support firmness and elasticity (aka less wrinkles), and magnesium to stimulate the skin and improve moisture levels.

I ended up using the serum twice a day — once in the morning and then again at night — before moisturizer and after cleansing. My skin immediately soaked it up. It’s not greasy or tacky on the skin, and the moisturizer and makeup I put on after seamlessly applied with no pilling. It’s almost the consistency of aloe vera. Though I was sent the half-liter bottle of it, which only comes back in stock once or twice a year and is about the size of a nice shampoo, I could tell that a little goes a very long way. Just squeeze out a nickel-sized dab and you can spread that amount over your entire face, neck, and décolletage. I was immediately impressed.

Because of my sensitive skin type, I can easily break out after using a scented product, and I’m pleased to report that this product has absolutely no scent at all. It has no dyes, either — it’s completely clear — and it didn’t burn or make my skin red or irritated, which has happened often with more potent serums. But even if this felt like a calming treatment, I could tell in a matter of days that it was really working. It’s winter here, and I have patches of psoriasis on my face if I get too dry. Day after day, I’d wake up with supple, moisturized skin from applying it the night before. My skin even felt bouncy to the touch.

I started applying it to the tops of my hands and then finally put it to the ultimate test: I applied it on a cat scratch and noticed that within 48 hours, it had faded significantly. Usually scratches like that linger on my skin for a week.

Given how far this product can go, a 1-ounce bottle can last you a while, but if you’re already sold, the 16.9-ounce bottle isn’t something I’d shy away from. Plus, you can only get it once or twice per year. Especially if you do struggle with extremely dry skin, the serum can be applied all over — from your forehead to your toes.

If you’re looking for healthier, bouncier skin in a matter of days, use the code SHOPISOMER15 for an extra 15% off through Feb. 29. You can use the code on either size of the Copper P Concentrate Serum, but also on any items from the Isomers line. Your dry, irritated skin will thank you.
