Is the $195 Eighth Day Replenishing Serum Worth Its High Price? Editor’s review


the Eighth Day Replenishing Serum at many skincare hype. It sold a huge five times about luxury e-tailer Violet Grey, whose founder — Cassandra Gray — shared Harper’s Bazaar that he makes your skin look younger.

What is your question? The actives that make up the serum’s patented peptide-rich plasma consist of 24 different bioidentical growth factors, peptides, and amino acids that the brand’s founder – Antony Nakhla, MD, dermatologist and board-certified dermatological surgeon based in Orange County, California – identified as key markers of skin healing over years of research and practice.

You might know platelet-rich plasma (PRP) from the vampire face that’s perhaps responsible for one of Kim Kardashian’s scariest selfies: The treatment uses injections of a person’s own blood to improve skin texture, reduce fine lines and wrinkles. PRP can be used to improve everything from hair loss to the appearance of stretch marks. “Platelets contain high levels of growth factors that, when applied to the skin, stimulate cell turnover,” says Ava Shamban, MD, Beverly Hills board-certified dermatologist.

Although the Replenishing Serum is, of course, not made from anyone’s blood, the synthetic peptides are said to have a soothing PRP effect on the skin.

Makeup artist Nam Vo recount Seduce she is a fan of the serum, adding that it helps after her regular microneedling session from facialist Aida Bicaj. These treatments usually leave her tanned and red for two days.

“The first time I used the serum was probably less than a day later and I was [already] completely healed, soft and supple, like dewy dumpling skin…” Vo says. “I find it incredibly healing and I love it.” So, yes: this luxurious healer in a bottle has developed quite the reputation.

What initially attracted me to this serum at around $195 per half ounce? For starters, like Vo, I regularly undergo in-office microneedling and laser treatments. Every time I get an in-office treatment, it leaves microchannels in the skin for a day or two that make the highly healing serums particularly absorbent. In the office, I might opt ​​for PRP, but once at home, it’s always difficult to determine which topical treatment will be the most healing and anti-inflammatory. This is where my love for the ingredients chosen by Eighth Day comes in.

The Regenerating Serum

I first started by incorporating the serum into my nighttime regimen, as I love combining growth factors with retinoids for an ultra-potent boost of skin-rejuvenating benefits. “Growth factors are signaling proteins [that] bind to receptors on cell surfaces to send commands for repair, rejuvenation, and replication,” says a New York board-certified dermatologist Hadley KingMD.
