ELS serum can be used directly on the skin as a daily rejuvenating serum. Apply the desired amount of serum to clean skin on the face or body daily, or as needed to nourish dry skin. You can also layer ELS with other serums and creams when extra moisture is needed.


Alternatively, you may add some of our other actives to create a world class serum targeted to your needs. This serum is the perfect base for CoEnzyme Q10 and our other lipophilic actives.


Please note that Alpha Lipoic Acid is already included in the serum and additional quantities will be difficult to dissolve.

Lipids are biomolecules grouped together not because of chemical structure, but on the basis of their insolubility in water and solubility in organic solvents. Lipids can have very different chemical structures and also diverse functions. They are the primary component of most cell membranes, energy storage molecules, signaling compounds, and enzyme cofactors.


Lipids are "built" from fatty acids and can be subdivided into two groups: 1) open chain structures including fatty acids, triacylglycerols, glycerophospholipids, sphingolipids, and glycolipids and 2) closed or fused chain structures: the steroids (including cholesterol).


Fatty Acids: Fatty acids have two major roles in the body: as components of more complex membrane lipids and as the major components of stored fat in the form of triacylglycerols. Triglycerides, sometimes called oils, are triesters of glycerin with three equivalents of fatty acid. Fatty acids are formed from two carbon units, therefore they usually have even numbers of carbon atoms. Hydrocarbon chains contain from 4-36 carbons. Although they are hydrophobic, they are amphipathic because of the -COOH group which can ionize so that shorter chains are slightly soluble in water. Fatty acids can be fully saturated or partially unsaturated; double bonds are usually in the cis configuration.


The properties of fatty acids are determined by the length of the chain and the degree of saturation. Fatty acids tend to aggregate with the extended chains packed next to one another. This close association promotes many interactions.


Saturated Fatty acids (e.g. animal fats, like butter) tend to be flexible due to rotation around the carbon single bonds. They have relatively high melting points due to the high degree of packing between adjacent unsaturated chains.


Unsaturated Fatty acids (many vegetable oils) tend to be more rigid and have relatively low melting temps due to the disruption of packing by the introduction of double bonds (fewer van der Waals interactions).


Other lipids that you will find in our ELS:


Glycerophospholipids or phospholipids (Phosphatidic acid is the precursor, there is no head group, just phosphate). They are made of glycerol backbone plus 2 fatty acids plus phosphate plus a head group (can be choline, serine, inositol). The head group is usually charged at physiological pH therefore these compounds are amphipathic, contributing to the stabilization of lipids in bilayer membranes.


Sphingolipids. Here sphingosine is the backbone, plus a fatty acid and the headgroup (choline or carbohydrate).


Sterols are formed by a steroid nucleus plus a charged head group. Steroids are amphipathic but -OH is the head group. Sterols, especially cholesterol, are the precursors for many important signaling molecules such as hormones. Cholesterol is a sterol in membranes that regulates membrane fluidity.


The steroid nucleus prevents crystallization of lipids at low temperatures, increasing the fluidity of membranes at low temperatures. The steroid also intercalates between fatty acid chains that have kinks due to double bonds, increasing non-covalent, molecule to molecule interactions at higher temperatures, so the presence of cholesterol decreases fluidity at higher temperatures


FAQ: What are omega 3? Why are they important?

Omega-3 fatty acids (also called ω−3 fatty acids or n−3 fatty acids) are fats commonly found in marine and plant oils. They are polyunsaturated fatty acids with a double bond (C=C) at the third carbon atom from the end of the carbon chain. The fatty acids have two ends; the acid (-COOH) end, which is considered the beginning of the chain, thus "alpha", and the methyl (CH3) end, which is considered the "tail" of the chain, thus "omega". The nomenclature of the fatty acid is taken from the location of the first double bond, counted from the methyl end, that is, the omega (ω-) or the n- end. Long-chain omega−3 fatty acids seem to have anti-inflammatory activity.

Omega-3 fatty acids are considered essential fatty acids, meaning that they cannot be synthesized by the human body but are vital for normal metabolism. Though mammals cannot synthesize omega−3 fatty acids, they have a limited ability to form the long-chain omega−3 fatty acids including eicosapentaenoic acid (EPA, 20 carbons and 5 double bonds), docosahexaenoic acid (DHA, 22 carbons and 6 double bonds), and α-linolenic acid (ALA, 18 carbons and 3 double bonds).

    "This product works great on my psoriasis symptoms which is something I expected because it's so well formulated. Usually doctors here in the UK recommend creams that have mineral oil as the key ingredient and not much more really;but I've always thought that psoriatic skin needs much more to be able to heal itself more quickly and efficiently and this serum definitely does the job.I've been layering ELS with the collagen and the CHAS serums and I'm more than happy with the results. If you wish to improve the health and appearance of your skin,this product is a must-buy!"
  • Author: Susan
    Can't do without this one. Use it right before Canvas Moisturizer Cream and then apply makeup. I have had sooo many compliments! Everyone wants to know what I do to get that glow!
  • Author: Mark
    Im in love with this product, it has made my skin very soft, in fact more so than anything I have ever bought at the department store. However I feel this product is more of an oil than a serum.
  • Author: Erin
    I have exceptionally dry skin. Previously I had been using Emu oil but it really was to heavy and I didn't see any improvement in wrinkles or age spots. I have only used this for several days but can feel the difference. Instead of sitting on top of my skin like some oils, ELS sinks in below the surface. It acts as a nice supplement to the eye cream and moisturizer. I will continue this as part of my routine. I am so glad I found Skin Actives.
  • Author: Marlena
    Great serum for dry skin, or skin that need replenishment. It is oily but absorbs fast and leaves skin smooth and nourished, without heavy feeling. I use it usually afternoon as a mask/night moisturizer.
  • Author: Angela
    Wonderful lipid serum. I use it every morning and evening, after applying my serums and creams. Locks in the moisture, leaves my face soft. I wait a minute until fully absorbed, then I apply my organic mineral make up.
  • Author: Jeanine
    With my very dry skin, this is a mush have for me. I apply this over my serum but putting a bit in my hand and rubbing my hands together and then patting the product onto my face. Then I apply my SA cream of choice over that. I'ave also added just a few drops to my moisturizer, mixed and applied. Either way works well, but laying it under the moisturizer seems to give a bit heavier coverage. I've also discovered that this serum (more of a oil in my opinion) is wonderful for healing tattoos. I used to use emu oil but have switched to this and I love it. It keeps it nice and moist wihout clogging my pores and making my skin break out. I use it as many times a day as I need to keep the tattoo from drying out. Rating: Can't live without it!

    Wonderful.. Love love love it!

    I've ordered many bottles of this, it works great for keeping my under eye skin in great condition. Love it, great moisture and packed with nutrients.
  • Author: Bee
    I've never used an oil serum before and I'm officially hooked! I added a bit of CoEnzyme Q10 which made it even more golden. It sinks in and feels like my skin is sighing happily. I can even use it around my ultra-delicate eyes! Sometimes I layer it on top of my Skin Actives night routine for extra emolliency (and sometimes I use Dream Cream). This definitely gives my face a dewy (not oily!) glow. Love it!
  • Author: Vanessa
    This product is so AWESOME it's inspired me to write my first ever online review! - and then I accidentally went and gave it 4 instead of 5 stars- I'm crushed. My skin is OSPW and I never thought an oil serum would be for me- I got this in the sample serum pack a few months ago and had never used it (I tried a little bit in my palm and thought 'eww that's like rosehip oil and no way am I putting that on my face'- and chucked it in the fridge). So it sat there and meanwhile I went on holidays, wore way too much makeup, drank too much alcohol and generally did everything you shouldn't for your skin including forgetting to take my skinactives. Let me tell you I was having the skin day from hell at the end of the skin month from hell. My skin had developed all these small red, non-sebaceous type pimples as well as areas of redness and cracking in all my creases, and whenever I got too hot it would burn and prickle--so basically my first bout of rosacea -yayh. I tried some of the other SA's on my skin but they only seemed to help so much. I'd bought them all for pigment control and wrinkles so they all seemed a little too harsh on my damaged skin. Anyway, enter skin day from hell (my face HURT and looked like a bad after shot from a chemical peel) and in desperation I washed my face and neck and just slathered this stuff on. I then immediately wanted to remove the oil slick (yuck) thinking that it was sure to give me real pimples rather than just rosacea type ones- but then I noticed it seemed to be absorbing a little bit and I decided to leave it on rather than subject my poor face to another washing. Another thing I did (and not sure if this made a difference) is to use a LED device I have on my face which I hadn't used in forever. Anyway the rest is history, 2 or three hours later my skin GLOWED and you could barely see the pimples as they had lost all of their redness. I went out without makeup and my friend complimented me on my fantastic skin! A week later now and the pimples are not just faded, they're actually gone, and even I (we're always harshest on ourselves right) think my skin looks fantastic, it looks and feels like velvety silk (not oily at ALL) and I think it actually looks better now WITHOUT makeup with nary a sight of acne. So verdict = this stuff is awesome, will definitely be buying the big bottle next time:)

    I layer this over the t-serum+antioxident serum in the morning before I apply makeup, and over the the t-serum+collagen serum at night before I go to sleep. Better than any moiturizer I've ever used. Best part= it does not break me out!

    I am 49 with dry, extremely sensitive, Lupus skin. I have tried everything to get moisture to my face. Everything has caused me severe distress, I.e. burning, flaking, redness. I read about this product on a forum for illness and it was recommended. I was skeptical as I can only use baby products. HAPPY to say to the world I have FINALLY found THE perfect moisture for my skin. I glow with beautiful skin now and absolutely NO irritation. Thank you SAS,,
  • Author: Christina McCarthy
    Wonderful product! Makes my face soft and gives it a dewy glow. Does NOT cause my face to break out. Also add it to some of your other products to boost moisture.
  • Author: Grace Castillo
    I started using this serum a week ago and already know I won't ever want to be w/o it. My skin has always been very dry and I have tried all kinds of creamy moisturizers I could think of with no success. I hated wearing makeup as it will only collect on my dry patches. Now, its been a week of using this serum and my skin is no longer dry! My skin is now so soft and plump instead of dry and withered. My makeup now applies beautifully but I feel there's no need for makeup now maybe only for special occasions as this serum has also given me a beautiful glow. I had my boyfriend use this for his rosacea too while we wait for the rosacea control serum to arrive. His face had cleared 90% and he has only used this for 3 days. This is a truly a wonderful serum! Please don't ever change it!
  • Author: Julia
    I have used this serum or oil, for a while and then didn't buy it again till recently. The formula much be a little different because although it works just as well, it smells like cod liver oil or some sort of fish and I have to make sure I only use the tiniest bit and mix with something else or my face smells awful and I can't stand myself. Due to this development I can't buy it again sadly. Since I see no where to actually rate this I will just say I give it three stars due to the odor.
  • Author: Lauren Carpenter
    This serum makes me feel like I am feeding my skin a super health meal. It does smell a little weird, and it took some getting used to for me, but it's a great product.
  • Author: Karina Andone
    Great product! I love it! I apply it before bedtime on top of the collagen serum all over my face and the eyes area and on my lips as well and they are not cracked anymore. I regret I did not discover SAS products before, I am a client for life and I will never use something else on my skin.
  • Author: barbara stoffel
    I love this serum. The only thing that plumps the under eye area for me as I have hollows under there. I need plumping action. this does it. it also put in folds between cheeks and nose and plumps there as well. I then add a bit to a chlorella serum I have and apply to face and chest and also hands. love love love.

    Amazing. I love it!!!!!!

    Hi Benjamin and thank you for the free sample of ELS serum with my order. I've only used it a few times over the past few weeks, and I don't have any issues with my lips, but when I have used it I like it. And yes it would be something I would order in the future. I'd prefer this over Burts Bees lip balm or things like that. Hope this was helpful. Have a good day!

    I never liked to use the older version of ELS on my face. I used it in many body potions, but I didn't like it on my face. This new version is another story. It just disappears into my skin. Love it! Yes, I would reorder it.

    I had never used ELS before. I have used it for the dry skin under my eyes,it is remarkable and very addicting. I always use undereye cream, but this is such an added bonus. It also seems to relax the wrinkles. I am 68 years old and loving it..Again, thanks for offering this..Carolyn

    I am new to skin active products and the last order I placed was my very first order with your company. I am so amazed at the results that I am getting from your products, not just a few but all of them.
    The ELS Serum is simply wonderful, I have a very oily complexion that is also dry, I have been using the ELS Serum for almost 2 weeks now. My oily complexion is no longer an embarrassment, my skin is now moisturized, and I have a shiny healthy looking complexion that I am proud of. Thank you so much.
    Sincerely, Michelle

    I recently purchased the Exfoliation Set and tried the new ELS serum right after using the Pumpkin Peel with Exfoliation Powder. Thank you for letting me try the sample! I would definitely consider purchasing the full size in the future as my skin was left super soft, supple and moisturised without any greasy feeling. I usually have dry patches on my cheeks with raised bumps, but after exfoliating and following it up with the serum i think it was a great way to treat my skin. I didn't even feel the need to follow up with a moisturiser so i think it is a testament to how nourishing the serum really is.

    I like that it seems like a rich oil at first but doesn't make my skin feel greasy afterwards. A little goes a long way, Ive had the 1 ounce size for about 6 months, using on my husbands face too and theres still some in the bottle. Makes my skin feel relaxed.
  • Author: Sedonia Sipes
    I love this oil! I use it in the winter time especially, right after washing my face. It absorbs into my skin within a few minutes. I have very dry skin and this helps me get through winter with no flaky skin. I use it under makeup and sometimes I layer it with plain canvas base cream.
  • Author: M.L.
    This serum is absolutely amazing! It quickly penetrates your dermis hence it doesn't feel oily at all. I now have a glow that makes my make-up look super polished and well-done! Beyond the superficial benefits, it, along with the Vitamin C, antioxidant serum and collagen serum (my morning ritual), have changed the texture of my skin and have definitely reversed the effects of my aging skin. Skin actives - Keep doing what you're doing. You are my mirror, mirror on the wall!
  • Author: Ally
    It definitely does what it says in terms of replenishing your skin with lipids. But what irked me was the fact that layering it with ANY serum would make them pill. Cream were even worse.

    This tends to happen when combining oils with silicons and is a big problem for most of us layering skincare under makeup --but this has never happened to me before sans makeup. (I used vitamin A, collagen serum and then this. It pilled but I just learned to tolerate it. But if I tried to add a cream, oh boy, it would come off in strips!)

    I found the same issue with A LOT of SAS products and since I wear makeup daily this is huge deterrent for me.
