What makes our Collagen Serum essential for skin health?

Magnesium ascorbyl phosphate- This stable form of vitamin C is necessary to promote the synthesis of  collagen.*


L-carnosine- Helps prevent cross-linking of collagen, one of the causes of wrinkles and loss of elasticity brought about by aging and exposure to sunlight.*


Hydrolyzed collagen- These peptides are obtained by the hydrolysis of fish collagen. They help supply your skin with amino acids that can be used in collagen synthesis. This is one of the few animal derived actives we have because plants don’t make collagen. That is why “phyto collagen” (a marketing invention) does not exist.*


Boswellia serrata- promotes collagen synthesis and is also an inhibitor of elastase (protease) and hyaluronidase (breaks down hyaluronic acid), a real life preserver for the dermal matrix.*


Betulinic acid- Helps to stimulates collagen synthesis and actively inhibits the enzyme elastase to prevent/correct the loss of elastic fibers responsible for skin suppleness.*


Hyaluronic acid-  Made of long chains of N-acetyl-D-glucosamine alternating with glucuronic acid, it can stabilize the intercellular space in connective tissue.*


Niacinamide (vitamin B3)- Can decrease melanin synthesis (important for hyperpigmentation), inflammation, itching (pruritus), UV-induced skin cancers, and prevents immunosuppression by UV irradiation. By increasing NADPH, the donor of reducing power in cell biosynthesis, it will increase synthesis of collagen, involucrin, filaggrin, and keratin.*


Epidermal growth factor (EGF)- Can increase protein synthesis. Excellent anti-aging active.*


Sodium PCA- This derivative of glutamic acid is very hygroscopic. It is naturally produced by our bodies, and one of the components of "natural moisturizing factor", which our skin produces to slow down water loss to the environment.*


Sea Kelp Coral- Contains fucoidans which are polysaccharides that can increase collagen synthesis. Fucoxanthin, a pigment unique to brown algae, can protect skin from UV caused aging.*

    I love the texture. So smooth. I made the mistake of adding it to my sonoran face cream and now I can only use it at night because makeup will not cooperate with this serum.
  • Author: linda mccann
    This is amazing; perfect. It goes far, absorbs with no residue or balling up. No colour, smell or irritation. Definitely feels richer than the old version, but no greasy feel at all, so also ideal for oiliest skin. I use it at night. You could wear make-up over it, but I prefer the Dmae celestrine spritz if I'm going out, for the perfect instant 10 year rewind - again, with no residue or balling. It really works long-term too. This is now one of my favourite products. See my Skinactives reviews on Make-up Alley - I've had so many emails thanking me for them. I am brutally honest, and I go into detail! Grab yourself a miracle! Get this and get your old, young face back!

    I loved the results of the original collagen serum but didn't like the texture. The texture in this is what you old one should have been, it doesn't dry as like a layer on your face and seems to absorb more. I got a sample of this and will be buying more! I used collagen serum throughout my pregnancy layered with rosehip oil on top and didn't get any stretchmarks. Stretchmarks are a genetic trait in my family, my mother and all my aunties have very bad stretchmarks, I truly believe this along with rosehip oil saved my skin.

    I can't ever be without this serum again. I went through my first bottle in 2 months, but the two bottles I re-ordered should last longer now that I've got the hang of application. I really only need 3-5 drops on a damp face & it soaks in beautifully. My pores have gotten smaller, if I need to extract comedones, they remove much more easily now &my facial contours have definitely gotten firmer. I will always make sure to have this serum on hand.
  • Author: Lauren Carpenter
    I use this product as a mask, because otherwise my face is super sticky all day/night. I didn't like the smell at first, but now it smells pretty good! It feels really great on my skin.
  • Author: Dariya Stoyanova
    I really like this serum. I purchased it mainly to fight the acne scars, but it definitely adds an additional glow and healthy look to my skin. I apply it after cleansing my skin in the evening (before moisturizer). Great product!
  • Author: Karina Andone
    I love this serum. I use it before bedtime because my face feels sticky. I do not like the smell, but it does not bother me. I like the texture and I apply it all over my face, including the eyes area and a bit on my neck. I used to have a kind of acne (little red points, I am not sure how to describe them on the right side of my neck) and it just simply disappeared since I am using this serum. In the morning my face glows and I am happy to see this. I find it gets absorbed nicely after the shower. I became a client for life of this serum.
  • Author: Glen Young
    This is a fantastic product. I cocktail it with dmae serum and antioxidant serum in a.m. At night I cocktail with every lipid serum(els). Doesn't get any better than this and sooo reasonably priced

    40yrs old, 6 children and 1 Grand child. I live in New Zealand and the NZ sun is the worst in the world due to our lack of ozone protection, so I do have the beginning signs of sun damage from being out on the boat fishing. In saying that I have used the same organic skin care line for the past 5 years and people still think Im 26-27yrs. After doing some research I decided I wanted to try some new actives so I could see if I could remain looking that age for the next 10yrs (Fingers crossed)!! Stumbled across SAS and just received my first order today and excitedly cleaned, toned and dried my skin and first applied the DMAE serum, used my blow dryer to dry it faster and then applied the Collagen Serum over top. 20mins later I look in the mirror and I swear I look a year younger 25 maybe? My skin had an amazing glow, firmer, yet supple and my pores seemed to be visibly smaller. So, SAS Im impressed so far and will continue to update my reviews with continued use and as I try the other serums. Thanks so much!!

    This is a really good serum, distinctly better than the ones I've used previously. Smoothens skin and gives it an even glow. This can really turn back the clock!
  • Author: Jennifer
    Love the way this feels, and skin definitely looks nice when in use, but gave me horribly vicious isolated breakouts. I naturally have oily skin and common acne. I'm 30, and was looking to this product to help with my collagen for my light scaring, but the sacrifice of having these monster isolated break outs, one after the other after following the usage directions for 3 weeks forced me stop. I'd love to know why this began happening, as I loved the serum.
  • Author: Mmill
    Great serum. I used it first when I got it in the serum set; visibly smaller pores, smoother skintone. I use it with the dream cream on my face, and sometimes pat a bit of EMUlator oil on top if I need more moisture. Recently I had a surgery, and ordered the 4 oz bottle of this, along with some other SAS products for skin repair. I used scar gel on the scar, and I used this under rosehip seed oil to care for the stretched skin around the area. It seems to help with stretch marks. I bet it would work well for woman who are pregnant, to help with belly skin tone before and after the baby. One thing: you absolutely must keep it in the fridge.

    One of my favorite products at Skinactives.
    It is great for using the morning after having used Vitamin C Serum, the night before.
  • Author: Skye Croman
    I love this serum. It melts into my skin, and I do believe it is working to soften and moisturize. I keep this with all Skin Actives in the fridge.
  • Author: Katie J
    Freaking amazing. Buy the bigger bottle, you'll use it all up. So my miracle story with this product is that I developed crepey skin on my neck and breasts in my late 20s, from being on a ridiculously restrictive diet. Diet was fixed, but some of the crepeyness hung around. I've been using this collagen serum for a couple months now on my face, neck, breasts, and some scars, and the crepeyness is gone, 10 years after I developed it. That's incredible. The skin on my face also feels a lot stronger - it used to be that if I slept on my side, I'd have pillow wrinkles on my face for at least an hour after. That doesn't happen now, which I didn't expect at all.
    Just FYI, I've found it balls up if anything grazes my skin, so I either wash it off before I put on sun block, or just apply it at night. I don't think it's meant to be worn under makeup.
  • Author: Simu Shahin

    I suffer from light pigmentation left over from previous breakouts, I don't have fine lines or wrinkles but I do get a lot of pillow creases on my nose area, and neck from sleeping on my back.

    I have used this for about 1 month consecutively and it's made a huge difference in the overall even-ness of my skin tone as well as my 'pillow creases' in fact I rarely get them anymore.

    I bought the Vitamin A cream in conjunction with this, but in my opinion, as I was using Retin A. The collagen serum works so much better with Retin A.

    My routine is:

    -Wash face with Cetaphil
    -Wait 20 mins
    -Apply Retin A
    -Wait another 20 mins
    -Collagen Serum
    -Rosehip oil(if needed)

    It's quite moisturising on its own and I don't usually moisturise after I apply this serum but my skin is on the normal side.

    Would also like to thank skinactives for their fabulous and amazingly patient customer service! xx

    Miracle wonder in a bottle! I have to admit, I have only been using this product for a short while--but visual results were apparent after only three days of use, something worth talking about. The fine lines under my eyes have truly softened and are not as noticeable after only two weeks of use. I have to admit, I am using Collagen along with several other SAS products but feel the collagen is the primary contributor along with SAS's Anti-Aging to the changes I am seeing. Combined the products seem synergistic. Other changes include smoother skin texture and tone. The only negative is the pump bottle. Because the Collagen becomes very thick when refrigerated, it is difficult to pump. I switched the collagen to a cobalt blue dropper bottle--perfect!

    I love all your products and have used them for years. Over the past month I am experiencing areas of contact dermatitis on my face and neck.
    I think it may be the collagen serum that is causing the irritation, because it is the one product that re-introduced into my regime caused irritation. Which ingredients, in your opinion, would be most apt to initiate irritation? I love the product and am upset if I have to discontinue it's use forever. Any suggestion would be appreciated.
  • Author: Roc
    I have only been using this for a week or so and i love it. It makes my skin glow and look evenly moisturized. I think that some people are saying its too sticky because they are applying too much. A little does go a long way. I do not mind the feeling at all and i even apply it before make up. I just really love how this makes my face look. It also does not seem to irritate at all or cause any pimples. I like this stuff better for under my eyes than the bright i cream with vit k added.
  • Author: Sam
    A perfect product. I bought the LMC formulation years ago but since they have updated it and it feels way better. Less sticky, not sticky at all. velvety in fact. I add allantoin and B5 to this formula. Use it a few hours after the vitamin A serum. Skinactives is the only way to go. All products are fresh and potent and formulated to perfection. Great to be able to add some ingredients to any formula too. Awesome staff who were kind enough to send me a free bottle as they accidentally sent me the 1 oz instead of the 4oz.
    Customer for life.
