Love this review, Kelly, thank you! For my purposes, I actually like that this is a lower-potency booster product, as I really just wanted something to mix right into my toner step for supplemental support rather than adding another high-octane formula to what I've already got going on. You sold me!

I love the way you describe things: a kiss of moisture, a whisper of emollienty... 😊❤

Thanks for covering this item! I recently bought it and have been using it as my AM essence to rehydrate my skin.

I have so many essence, toners and peptides, so I’m not in a rush to try it …..yes please Kelly a deep dive into single products. As always very informative ❤️

I wouldn’t mind seeing like 2 or 3 products in one video. Like detailed of each one like this one and I wouldn’t mind longer videos from you either ❤ love the sweater

I enjoyed the deep dive, thank you! 😊 definitely up for more like this 👍

I ordered this so fast once it released, and I've been using it religiously twice a day every day since. And I LOVE it. It is such an affordable product, and it is soooo light and hydrating.

Love your reviews, as always Kelly.

I've been using this toner and have really enjoyed it. I've found it both hydrating and plumping. It doesn't leave a sticky residue.

I am always amazed how deep down and thorough you approach to every product and in the end i have all my questions answered when im thinking whether to buy product or not. Keep up, you are the best skincare youtuber we have ❤

Great review Kelly much appreciated 👍 iv added it to my skincare range as i love essence and toners ❤

🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍 LOVE this one!!!!!!! It’s perfect to put on first!!!!and it just sinks in and vanishes!!! And my following serums soak in so nice!!!

Is it ok to combine with retinol and can be use everyday?hoping for your reply,Thanks in advance

I love this serum, been using for 1 week and my skin is so smooth and plump, and it does help boost other serums works better that you apply after this serum. I only got the 30ml version to try, very impressed with the results and will repurchased a bigger bottle.

It works as a great serum for both face and body given the size. I felt the brightening and plumping effects within a few days of use.

Just picked this up at my local Marshalls, too soon to see real changes but my dry, dehydrated skin feels much better. Thanks for the in depth review!

Hi Kelly, I love your detailed review of this product. Your choice of descriptive words enables viewers to understand how the product feels on the skin, and thereby make a choice whether the product is suitable for their skin type and their skin concern. I would also love to see in future videos that a few similar products (maybe 3) can be done together in the same review. For example, in this skin booster review, Torriden booster can be done together so that viewers have a good understanding which product is for their skin type. I think it would really be interesting. However, I still love your review in this video. It helped me made my choice on my "skincare wish list". Thank you!

Great review! I just received this product and can't wait to try it. On another note, your hair looks gorgeous! Please share and review the hair products you use :)

I feel like the obvious solution to the limitations of this product being less concentrated is to layer it to achieve a more effective dosage. If it's half as concentrated as other products but you do 2 layers that should accomplish similar results. And it seems to be decently hydrating and not too heavy. So how do you feel it would be if you did multiple layers in terms of comfort and elegance?

every skin is different, and how those skincare goes to your skin depends as well on your living lifestyle. but for me it works better. just wanna say this influncer is base on her skin. and we have differemt kind of skintype. but this serum hits different when you added it in your skimcare routine

kelly, just winder what your thoughts are on Paula’s Choice peptide booster?

I’m so glad you brought up the issue w peptide concentrations in this review, also thanks for the breakdown of these specific peptides. So many products now have a few peptides listed at the bottom of the inci. My skincare skeptic says that is more for the purpose of marketing and internet searches than efficacy. Are peptides (generically) the new hyaluronic acid? It also seems their acceptance as a must have ingredients is probably ahead of any independent evidence. Doesn’t mean the claims are false but I do wonder how much some of the results people get is due to their hydrating properties rather than collagen building, especially the plumping effect. However, my skincare skeptic isn’t in charge of my skincare purchases 🙄. I do use a dedicated peptide product am and pm. I use the timeless CoQ10 serum with matryxl 3000 (the OG) in the morning. In its faq, they say the matryxl is used in the manufactured recommended concentration range. I’ve recently purchased Stratia’s Interface. I trust that brand to us ingredients within recommended concentrations. I’ve been using Acures radically rejuvinating night cream after my retinoid. They don’t disclose percentages but the list of peptides (which are identical to drunk elephants protini) are in the middle of the inci. Like @lilm1018, I’d be very interested in learning more about the specific peptides, their recommended concentrations and if there is any research beyond what the manufacturer or skincare company releases. Also multi-peptide products that could stand alone for anti-aging. Very useful review on this. I’m not going to replace any of my peptide products with this but I may give it a try in the summer as a hydrating toner/essence (with possible additional benefits).

@KellyDriscoll

7 ай бұрын

Peptides are usually used in concentrations lower than 1%, so they often appear near the bottom of the inci regardless. Of course, there are exceptions, but peptides are actually effective at low concentrations, and depending on the formulation and how the peptides are delivered into the skin, a very low % can show good benefits. So it's less important to know the % of individual ingredients and more important to get an understanding of the overall formula, especially when more than one peptide is being used.

I've been using about a month, AM and PM. Usually four pumps to take down my neck, and between my toner and essence. My essence is thicker/has more body. How many pumps do you use?

Would you recommend this to rosacea prone skin?

Thank you for your review. I recently tried this booster. Upon the first application, I experienced buring around my mouth and chin. I didn't use it in my PM routine. The following morning, I had a LOT of white pimples on my chin, around my mouth, on my forehead, and the outsides of my eyebrows. I plan to return the booster. This has never happened to me in the past with skincare.

Just bought this .. can I use it before minimalist multi peptide serum? ❤

What product do you recommend for brownish spots under and the side of one’s eyes? Hence…I’m a 54 year old male.

Kelly, maybe you could try to use it as a first essence rather than a first step-serum? It's how I have been using it based on my understanding (though not sure if I'm using it correctly haha), the benefits it gave me is helping my hydrating toner dive more deeply and also significantly cleared up my texture in less than a month! (I'm also on tretinoin) Though I don't know if layering it on first before toners would make a difference.

I guess it depends on the texture of your toner and how your skin absorbs the product, but I think it might be a touch thick as a first step before toner. But if it feels good, do it that way; it won't affect the benefits one way or the other. Just depends on your products and how your skin soaks it up!

I've been using it as my "toner" step on dry skin after cleansing (I have combo acne prone skin and my steps are double cleanse, toner (thinner, more for hydration), essence (thicker, optional, more for moisture if skin needs it), barrier support serum of some kind, treatment serum of some kind (higher concentration active, usually retinal), and moisturizer). This is my first time using peptides in my routine, and I have noticed a big difference in my texture (skin is much smoother) and elasticity (skin has way more bounce)), in just a few days! What I like about it: - good for peptide beginners and for oilier skin, versatile and fits easily into am or pm routine - gives you ability to combine peptides with other actives as opposed to many peptide products where you can't use them with retinol for example

You'll want to pair it with your favorite serum and possibly a hydrating toner. Always order your products from thinnest to thickest, it would generally be Toner -> Cosrx Peptide -> Serum -> Moisturizer -> SPF (AM)

Kelly I would love if you could talk about the concentration when we discuss peptide products. I've used this product a couple times and I like it, but I wonder if the amount/% of peptides in it are even in the efficacious range to act as a "booster". If it had other extracts or actives I'd be okay with a mild peptide cocktail, because there is other support, but because its sells peptides, I question the amount.

@KellyDriscoll

7 ай бұрын

Peptides are usually used in less than 1% in all formulas, so it's hard to talk about percentages/concentrations when it's so low and the info is usually not publicized. That being said, that low amount doesn't mean they aren't effective; they do work at very low concentrations. But due to the price and amount of product, you can make an educated guess that it's not going to be as concentrated as a similarly costing product at, say, 30ml vs the 150ml cosrx has.

Are you using retinoids? Those would be the very best for firming the skin. Peptides help but they aren't the best single ingredient for your concerns. A good retinoid product is the first step, along with daily sunscreen. You can add a peptide to your routine after that. I prefer copper peptides like from NIOD or Peach and Lily.
