What the gurus are saying

This serum delivers immediate plumping that holds up with regular use, and gurus praise it especially for anyone steering clear of snail mucin or needing deep hydration. The vegan growth factors and copper peptides earn consistent marks for firming and soothing effects, though one expert notes it hydrates and calms rather than actively boosting collagen production, so it pairs differently with other actives than some alternatives do. One caution from dermatologists: don't layer it with ascorbic acid vitamin C in the same routine, though gentler ester C works fine.

"I'm almost out of my elastic skin from In Beauty, but that's another great option for a vegan version. Not as affordable though, I will say that."

"This is the In Beauty Elastic Skin Serum, and I absolutely love this serum. It's vegan snail mucin plus some copper peptide, and I really think In Beauty did an absolutely incredible job on this product. I think it proves that you don't have to feel like you're missing out if you prefer to go the vegan route instead of using snail mucin."

"The elastic skin is such a great vegan alternative to snail mucin."

*Mindfully* Shopping the Sephora VIB Sale

"I like this product, but I went into it because of the copper peptides since I'm a big peptides fan, and ultimately I found that [...] this did not replace my favorite peptide serum, which is the Peach and Lily peptide serum. [...] I can still see how you could like this more than the Peach and Lily. The texture really does feel like Kosterx snail mucin, but it's a fully vegan product, and I've come to really appreciate that category."

"I do like the texture they came up with for this serum to mimic the [...] snail products, but ultimately I feel like I saw a lot more in my skin from the Peach and Lily copper peptide serum. I liked this overall, I like In Beauty as a brand, they're cute and [...] the price point is reasonable, but if you made me pick between Ulta and Sephora for a peptide serum, I would go to Ulta for the Peach and Lily."

"It doesn't have a super blue shade to it, but it's not like super blue like some of the other ones, and it's nice and hydrating, feels really nice on your skin. It also contains wild yam root, which is the closest thing to vegan snail mucin, niacinamide, beta-glucan, pineapple, panthenol, and some nice soothing ingredients, allantoin and vitamin E. But I will mention not all of my viewers on this channel are a fan of this brand. They've had some issues returning products."

"The second you apply it, your skin instantly looks plump, plumper, and with long-term use, it also helps to firm skin up as well. [...] It's got kind of a lotiony texture to it. A little bit goes a long way. It feels a little bit like snail mucin on skin, and it's really nice because it's got that wild yam extract, which is called vegan snail mucin. [...] It's got copper peptides in here. It's got [...] a plant-based peptide that improves skin density as well as elasticity."

"I think it's yam root. So if you are vegan and don't like snail mucin, or you're allergic to snail mucin because some people can be, this is a really nice option. It's great, it's got a nice plumping effect and it's great for soothing and barrier repair. It's got kind of a goopy texture to it. [...] Doesn't that texture remind you of a snail mucin serum? It does, because it's so hydrating and kind of goopy. I don't know how else to describe it."

iNNBEAUTY PROJECT Elastic Skin Firming & Plumping Refillable Serum Review, How to, and Dupes

"For what it promises, visibly firm plump skin while targeting aging and intense hydration improving look of facial contours for skin that feels elastic, I would say this does most of this. It doesn't do much for facial contours, I don't really know that there's a topical product you can use to help with your facial contours, maybe the plumping helps a little bit, but otherwise it delivers on all of those. It's quite wonderful in terms of hydrating, soothing, anti-aging."

"Another product, the In Beauty Project Elastic Skin Firming and Plumping Growth Factor Serum. I really enjoy this one, and if it's 20% off, that's even better. I think I got this at regular price, but it's a really nice brand and this is a really nice serum. The packaging is nice, it's got good ingredients, there's no scent to it. I really enjoy it. If you're vegan, it's a nice alternative to snail mucin."

"I just absolutely love this formulation. This is definitely more advanced than The Ordinary in my opinion because it contains more ingredients to improve the skin. This is great for all skin types, but if you have dry skin, sensitive skin, or let's say you're someone that really loves that deep hydration, that plumper, bouncier looking skin, then you're going to absolutely love this. It has peptides as well as copper peptides."

"If you're looking for a nice hydrating plumping serum that helps to rejuvenate the skin then I would say look into this. It has a nice pump, you can purchase a refill once you're finished, and you are getting 30 mls of product. I've paired this up with retinol, with other types of peptides, I did use this with vitamin C a handful of times in my morning routine, I've never experienced paling, and everything layered up so nicely."

"I was using this with truth serum, copper peptides, regular peptides, vitamin C, and honestly this layered and paired up nicely with everything I used with it. There was absolutely no pilling, especially when I got to my moisturization stage, my sunscreen, and my makeup. Everything was just layering so nicely. There's 30 mLs of product here, it comes with a nice pump, and you can purchase a refill as well, so you can keep the packaging and just take this off, put the new one in, and off you go."

"Next product that I've tried before Allies of Skin is from In Beauty Project. It's called Elastic Skin and it retails for $46 Definitely probably the most affordable product that we're talking about today. This is a vegan derived uh product formulation that contains growth factors along with other ingredients that helps to visibly lift firm and help to deeply hydrate the skin And I really enjoy the hydrating nature."

"The In Beauty Project Elastic Skin Serum is a more affordable option [...] for 42 bucks and it has encapsulated vegan growth factors at 6%, it also has copper and biohacking peptides. [...] Copper peptides help with anti-inflammatory effects and help with the aging process. Just don't use this in the same routine as your ascorbic acid. You can probably use it with Ester vitamin C, so if you're using an active vitamin C [...] use this at night and use the active vitamin C in the morning."

What $295 Gets You in Growth Factor Serums vs. $46....EXPOSED! | Dr. Idriss

"So what does that mean? It means you're going to get a lot of antioxidant effects, a lot of anti-inflammatory effects, good hydrating effects, but it's not necessarily going to boost your collagen, so just be aware. And this is 46 to 48 bucks. If I get asked do you just buy this instead of the other, they're different, it's not the same. It may sound the same, but they're different because they're derived from different sources."

"It is their firming and plumping growth factor serum. It's a silky, lightweight treatment that has peptides, growth factors, and brightening botanicals. It gives your skin this instant, juicy look with the long-term benefits of lifted and smoother skin. This just makes my face feel bouncy and alive."
