What the gurus are saying

This serum pairs peptides with growth factors in a hybrid cream-to-serum texture that earns consistent praise for delivering visible lifting and anti-aging results, though the plant-derived growth factors are less advanced than pricier alternatives and require patience and consistency to work. The trade-off is real: you're not getting the most potent formulation available, but you're paying a fraction of the cost while still getting peptides, hydrating ingredients, and collagen-boosting actives in one product. Those with oily skin may want to use it as both moisturizer and serum; anyone prone to dryness should layer a separate moisturizer on top.

"It's an amazing option with growth factors and peptides together. This comes at a fraction of the cost of other recommendations, but just know that the type of growth factors used in this isn't quite as advanced as either of the other two. So you are compromising slightly, but for that price point, honestly, I think this is wonderful."

NEXT LEVEL ANTI AGING - 4 Secret Anti-Ageing Ingredients

"If you're looking for a cheaper alternative then the stratia interface is finally back in stock love this serum it was out of stock for the longest time it's back and it's a great affordable growth factor serum"

New ADVANCED ANTI AGING INGREDIENT - Growth Factors Skin Care

"One of my favorites comes from Stratia, which is their Interface moisturizer. Unfortunately this is currently sold out. I spoke to Stratia and they said that we're going to be bringing this back at some point early 2024, so watch this space. But this also contains growth factors in a more moisturizer format. The Allies of Skin is definitely a serum, this is more of a moisturizer, a cream base."

Peptides Are Not Over! BEST PEPTIDE SERUMS 2024

"If you're using a peptide primarily for firming and tightening the skin then the best hands down goes to Stratia and their Interface serum. This uses a potent blend of peptides alongside growth factors which are going to give you that maximum lift and tightening result. [...] Peptides are phenomenal when it comes to anti-aging boosting collagen and elastin but combining with growth factors is like the best way of getting maximum results."

"I think you just have to set your expectations, be a little bit more patient, and keep with that consistency to see those results. If you can do that, you'll get some phenomenal outcomes when it comes to anti-aging. [...] For the price point, which is super affordable, they've put everything they can into this serum. You've got the anti-aging peptides, you've got the pro collagen growth factors, you've got a blend of hydrating and plumping ingredients. It's just such a nice product."

My MORNING SKINCARE ROUTINE At 40 - Better Than Botox

"I think the other is slightly more high potency, but the Stratia one is a lot cheaper, so there's something here for everyone. Don't feel that you have to miss out on growth factors just because you can't splurge. That Stratia one actually is really, really nice. I usually put one and a half pumps and that will do all of my face and I'll take it down onto the neck too. Growth factors are great for boosting collagen and elastin."

SKINCARE LIVE - Celebrating 5 Years On YouTube

"I think having experimented with a lot of neck creams, I genuinely think the one that's had the biggest difference on my neck is the Stratia Interface. It's not even a neck cream, but I just used it on the neck where I get tech neck because I'm looking down a lot, and it really worked. I've tried lots of bougie expensive neck creams, and I think the Stratia Interface hands down has worked better than all of them."

ULTIMATE SKIN FIRMING CREAM - Tighten Sagging Skin and Get Rid Of Jowls

"This is one that I've used very regularly over the years and always always gone back to because again it just works. [...] This gives you that dose of growth factors which is present in the Allies of Skin one but a much lower price point. The difference here is you're going to have to persevere a little bit more for the results so the potency isn't quite as high with the Stratia one versus the Allies of Skin but it's a fraction of the price point."

Worlds Best: ANTI AGING SERUM 2024 (Only $27!)

"I honestly don't think it's possible in 2024 to find a better serum than the Stratia Interface. If your budget doesn't stretch to pairing it with other products and you just want one serum, honestly Next Level results from the Stratia Interface. It's so good. [...] The second I found that it was back in stock I broke my leg like delving to that site to put some on order. I bought a couple because I never want to be without this again."

"I would say reach for the Stratia Interface serum. This is a really really nice serum that contains peptides alongside growth factors. And whilst it might not have the same technology which the Allies of Skin one does, it comes at a fraction of the price. In the long term, you're still going to get some next level results as long as you're consistent with it."

Worlds Greatest ANTI AGING SERUM - Growth Factor Skincare Battle

"The peptides that they've chosen are really clever, really shows that they've chosen quality over quantity in this serum, delivering the peptides that are going to have the maximum impact when it comes to boosting collagen, firming the skin, tightening and lifting. I honestly think it's hard to fault this formulation. [...] To me this is absolute perfection. [...] It's all in [...] one, so you don't have to use a peptide serum alongside anything else to get the maximum anti-aging benefits."

SECRET TO FIRMER SKIN - Best Growth Factor Skincare

"Stratia are an amazing brand known for their next-level formulations and their affordable price point. This comes in at about $28, which is super budget friendly. When you look at the formulation, you're getting a sensational blend of different growth factors alongside great peptides and some other great hydrating and plumping ingredients too. For the price point, this formulation is 10 out of 10. I've recommended this serum on the channel so much in the past and I stand by that."

"The Stratia Interface is a great option if you're looking for growth factors on a budget. [...] It's the same rich velvety cream-like serum hybrid, it's got those growth factors, additional peptides, it's kind of doing everything. I don't think I've skipped a day when it comes to my growth factors for the past 6 months and I don't plan on anytime soon, but I might switch it up to a more affordable option and the Stratia Interface is perfect for that."

Ultimate EVENING SKINCARE ROUTINE - Boost Collagen FAST

"Stratia Interface is a growth factors serum which I think is quite advanced. [...] For me it just works. I'll tend to put two pumps and that'll do the whole face and the neck. [...] I do definitely notice that I've got some lifting and I've got some great anti-aging from including growth factors. I think growth factors are one of the most potent when it comes to anti-aging."

If your budget doesn't stretch to it have a little patience use the Stratia and it will definitely definitely pay off."

"Interface is Stratia's new peptide moisturizer, and [...] I'm quite a fan of peptides. It has repairing peptides in it and it's more of a midweight moisturizer. Mixed with Lipid Gold's ceramide lipid rich formula it covers all my bases, to the point that I really may not need a serum if I use them together."

"I absolutely love this, unsurprisingly, because I do really well with peptide ingredients. The only thing I don't like about it is that I don't know when I'm running low, so before I recycle the tube I'm going to weigh it to try to get an estimate. I did repurchase the upgraded version of this one."

"I do a lot of product comparisons on YouTube and Stratia is one where it's like I don't usually find dupes or like super comparable or like the ingredients are the same but the effects are not, the performance is not. So I think that's actually, I really just have to commend you because like the space is so crowded to be able to kind of figure out what is a different take or something new is just increasingly I think becoming harder, but you're doing it which yeah it's very impressive."

"Very nice moisturizer, no fragrance in it, works well for most skin types. In here we've got seven different peptides including epidermal growth factor, we've got rose hip oil, acetyl glucosamine which is another great ingredient, licorice root and allantoin both for soothing skin, really nice product. This is one you can use daytime or evening, either one or both. It's nice in my opinion."
