I worked on this and surfaced a few major themes. There was a lawsuit in 2014 that a few people talk about, but that appears to be sorted out now.
It's extremely well loved on Reddit but there's some nuance that it's probably more helpful for older users (e.g. 40+), particularly those with scaring.
I also included a few other notes about the 'pump', the different versions, and making sure you buy an authentic version. Hope it helps!

TNS Advanced+ is a dual-chamber growth factor serum built around what SkinMedica calls NouriCel-MD — SkinMedica's proprietary blend of proteins, paired on the other side with a peptide and botanical complex. Do note: the formula contains no Vitamin C and no niacinamide, two actives most consumers assume a $295 'anti-ageing' serum would include.

Dermatologist Dr. Leslie Baumann MD shares her scientific opinion on this antiaging serum. Is this serum good for your skin and safe? How does it differ from TNS Recovery Complex & TNS Essential Serum? Learn which anti-wrinkle serum to use in your skincare routine and how to use it with retinol.
It does not have the ascorbic acid in it that your skin requires to make collagen, so I recommend cycling in a Vitamin C serum in your routine at least 3 times a week.
Dr. Baumann is a board-certified dermatologist but she also sells SkinMedica through her Skin Type Solutions store, so read her writing as a commercial voice with real expertise rather than a neutral one. Her actionable advice is still useful though: pair the serum with a separate Vitamin C three times a week, since TNS Advanced+ is telling your skin to make collagen but not giving it the Vit C it needs to actually do that.
The biggest cloud over this serum is a 2014 lawsuit that alleged SkinMedica failed to adequately disclose safety concerns around the growth factor. The lawsuit was dismissed in 2018 though, and I could not find much detail on it beyond that. Additionally, from the research, I could not find any clinical case linked to TNS use or serious widespread concerns about its use. I recommend checking with your dermatologist if you have concerns.

The primary-source summary of what the 2014 Ruhnke lawsuit actually alleged and how it ended. Key nuance most write-ups get wrong: the suit was about disclosure of potential risks, not anyone actually developing cancer, and it was dismissed with prejudice in January 2018 — not 'settled,' not 'abandoned,' and the reasons were never publicly disclosed.

Abbvie/Allergan (the companies that make Skin Medica) have an employee program in which employees can get the products for deeply discounted prices. It would surprise me if they would open themselves up to internal liability that way, but I've been surprised before with pharma conduct. The case was settled out of court in 2018. Looking at the literature, the risk appears theoretical, and would be similar to the rest of the companies who use growth factors in their serums (like Merz). They likely do not have enough long term follow up data to conclude one way or another, as cancer can take many years to develop.

I asked my derm that question about a different product with human growth factors, as I have a history of skin cancer. She said there's no evidence that it's dangerous and she uses them in her own routine.
Role of growth factors in skin creams. Authoritative facts about the skin from DermNet New Zealand.
DermNet NZ on where the science actually stands — this is as close to a neutral textbook summary as exists. The honest takeaway is that growth factors are large proteins with limited skin penetration, and long-term safety data on topical use is still thin, so the 'it probably can't hurt you because it probably can't get in' argument is doing a lot of the heavy lifting for this entire category.

The aging process involves numerous biological mechanisms that have been characterized and proposed as the “hallmarks of aging.” Targeting the processes and pathways related to these hallmarks of aging that cause and promote skin aging could provide ...
The most recent peer-reviewed clinical study on TNS Advanced+ specifically. Worth reading if you want the actual efficacy data — but note that the authors are SkinMedica/Allergan-affiliated, and that's representative of basically the entire clinical literature on TNS. Independent, non-affiliated studies on this exact product are essentially absent.

Remember you will only find it worth it if you have skin issues that GF [growth factor] will address. If you're young, have no set fine lines or have healthy skin with minimal damage/scarring you probably won't see any difference at all and it won't be worth it. Those are the types of people who I see post reviews and claim that it did nothing at all.

My husband and I both use the TNS serum. He jumped on the bandwagon after seeing my results. In fact, just today we were looking at photos and he remarked that my 3 chicken pock scars from my face are gone. GONE GONE. I have had those scars since I was 6 and I'm now 48. I believe TNS and Tretinoin have taken decades off my face and I now have zero texture.

I am glad it helped you. My experience was opposite. I used the whole bottle of TNS advanced + serum and didn't see any results or any improvements. None. Very disappointing considering it's crazy price tag. I am 41.

Yes and no. I like the stuff, and it does work. I keep thinking it doesn't, then go back to it and look better. BUT, after using TNS advanced for over a year, now maybe closer to 2, I think other GF serums work better for me for wrinkles and deep lines. I like TNS a lot for overall face looking firm and something hard to be specific about but looking better and younger. But it was night and day on deep lines with neocutis for me being WAY better. So now I use TNS in AM to get good tightening plus other at PM.
The dual-chamber pump was the product's most universally complained-about feature — SkinMedica actually rolled out a redesigned actuator in 2024–25 specifically because of the complaints. Do try to check you are getting your product from somewhere that sells with the upgraded pump.

I love this! I use this everyday and have been for the past year. My only complaint is the dual pump. I'm awaiting a replacement because 1 side of the pump wasn't pumping

Absolutely do not buy from Dermstore. They advertise the new bottle and sell the old bottle and it's defective every time. Even upside down. Even pressing the air out. Even doing all the tricks it DOES NOT work and they refuse to replace it.
I had to look on Reddit for this. Recovery Complex is a more concentrated shot of growth factor, Advanced+ pairs a diluted growth factor side with a peptide and botanical side, and some long-term users actively prefer the older Essential formula that Advanced+ replaced.

I used SkinMedica's live chat option and asked this question. The response was literally this: The TNS Advance + serum is for: Rejuvenate skin, Reduced appearance of fine lines and wrinkles, Enhanced skin texture and tone. And the TNS recovery is: Rejuvenate skin, Reduced appearance of fine lines and wrinkles, Enhanced skin texture and tone. I was like, umm, so they do the same exact thing? And then she just referred me to the medical info team. So I thought I would come here for help.... Anyone know what the difference might be between these two products?

I used it for about two years before finally switching back to the classic TNS, and I don't miss it. TNS Advanced+ Serum contains a lower concentration of TNS, AND it doesn't include Vitamin C, green tea, CoQ10, arbutin, or ergothioneine like TNS Essential Serum did. Yes, it begins to work faster and it doesn't have that distinctive scent, but absolutely none of my autistic-special-interest-level skincare research has found any signs that TNS Advanced+ Serum provides better results than classic.
Online listings priced much below retail are very likely counterfeit (SkinMedica itself publishes a warning page about unauthorised resellers). ++ do note that Reddit users with long TNS experience are unanimous that half a pump is enough to cover the whole face.

Three pieces of practical advice packed into one comment — use half a pump, consider the Recovery Complex instead if you're not getting regular procedures done, and treat any Amazon or Sam's Club listing priced much below retail as a counterfeit signal. The 'half a pump' point in particular is brand-agnostic advice the brand itself won't tell you.
Yes - BUT unless you have procedures regularly you're just as well off with the TNS recovery complex which is $65 dollars cheaper. Another trick with all the Skinmedica products is using half a pump - it's really all you need and it will last you a much longer time. I'm on my third eye cream, but everything else has lasted months using a half a pump 2x a day. Also, do not buy this from Amazon or Sam's Club - if it doesn't cost around $200 it's not real.
