How It Works

Camellia Oil

Sourced from Japan

Rich in hydrating essential fatty acids responsible for increasing skin’s suppleness, elasticity and moisture levels.

Sacha Inchi Oil

Sourced from Peru

Renown for being the highest plant-based source of Omega-3 linoleic acid, reducing the occurrence of breakouts and clogged pores.

Amaranth Oil

Sourced from Hungary

One of the few natural sources of squalene, which skin cells produce but decreases as we age, delivers antioxidants and smoothes fine lines and wrinkles.

Prickly Pear Oil

Sourced from Tunisia

Abundant source of Vitamin E, this antioxidant accelerates healing, protects skin from UV damage and collagen breakdown.

Helichrysum Oil

Sourced from Italy

Powerful antibacterial properties of this essential oil keep breakouts at bay as tissue regenerating diketones reduce the appearance of scars and induce vibrancy.

Passionfruit Oil

Sourced from Peru

Contains pro-vitamin A, decreasing appearance of uneven skin tone and enhancing skin texture.

The Process

Premium quality oils are sourced raw, organic, unrefined and non-deodorized for maximum nutrient density. Therapeutic grade essential oils are distilled from wild medicinal plants. Twenty active + skin loving ingredients are hand blended in synergistic quantities proprietary to Root Science. Tried and tested by real people to ensure optimal skin benefits.

The Experience

An intoxicating whirlwind of crisp citrus, sweet floral and warm honey notes arouse senses and invigorate skin. Serum warms in the palm of your hand and nutrients are gently massaged into face and décolleté. Lavish botanicals drench complexion in glow activating vitamins as moisture rich oils quickly absorb, unveiling perfectly primed skin and a new state of health.

The Standard

Housed in stunning dark violet glass for the highest standard in freshness and potency. Concentrated, water-free formula eliminates fillers and preservatives. Pumps instead of droppers reduce oxygen induced rancidity. Violet glass instead of clear prevents light degradation. Purest form of organic + wild crafted ingredients are protected for skin safety and efficacy.


Featured Ingredient: Tamanu Oil

The tamanu tree is indigenous to tropical Southeast Asia. It takes 220 pounds of tamanu fruit; the amount one tree produces annually, to yield only 11 pounds of this cold pressed oil. For hundreds of years, tamanu oil has been used by the region’s natives to heal numerous skin ailments. Studies on tamanu oil have proven it to be comparable to that of an antibiotic when alleviating certain maladies, due to its lipid content, specifically the antibiotic Lactone. Tamanu has also been studied for its ability to reduce the appearance of scars, with results nothing short of a miracle. Valued for its superior healing benefits and skin regenerative properties, tamanu oil also contains anti-inflammatory, antimicrobial and antibacterial properties as well as fungicide and bactericide agents. This incredible oil also promotes new tissue formation, accelerating healing and healthy skin growth. For the aforementioned reasons, tamanu oil is revered as an overall healer of most skin ailments, and that is why WE LOVE TAMANU OIL here at Root Science! You might notice we use it in almost all of our facial moisturizer formulas – how could we not!

    This product is just amazing for your skin. Seriously, try it, you won’t regret it.

    I’ve always had sensitive skin, but when I was pregnant, it was even worse! I didn’t have that natural “glow” everyone says comes along with pregnancy. Instead, my skin teetered between very dry and itchy or oily and broken out. This serum saved me! It helped balance my skin so I could feel my best even when I was feeling my worst (yay morning sickness). I finally ended up getting that pregnancy glow I heard about. I would recommend this product to all the pregnant mamas out there going through the same struggles! And you can feel good knowing that the ingredients are organic and safe for you and baby. Thanks Root Science!

    Best serum I’ve ever used! Leaves my skin well moisturizer and glowing. It soaks right in and isn’t greasy at all. I love the natural all organic ingredients, I like to think of it as “skin food”! All the other products I’ve tried from Root Science have been of the same high quality! For example the facial exfoliant “Polish” is a must!! I love this company!!

    I never write reviews, but I am going to for Root Science Youth Serum. I have been using this product for about a month and my skin has never looked better! I was even asked if I used botox to get me skin so firm – indeed NOT!! It is all this wonderful product! Thank you Root Science for being such a great company with amazing products that I can feel good about using. Your costumer service is amazing – please don’t change!!

    If I could put love in a bottle…it would resemble the feeling of putting this serum on your face. I cannot say enough about how happy I am with this product. I love love love it. I’m not the type to write reviews but being someone that has wasted SO much money on skincare products, I feel it my duty to sing the praises of Root Science. Gah, it’s the best! Do yourself a favor and buy this. My skin went through a short detox period where I broke out a little but once that was over, it was thanking me. My skin has never been better and I finally feel like I’m actually nourishing my skin for the first time! My only complaint is that the bottles are so dark that you can’t see how much product you have left. I have no idea when I’m going to run out. A little goes a VERY long way but it’d still be nice to know when I need to get more before it’s gone…because there’s no way I’m going again without Root Science in my life. Thank you, thank you!!

    This is a lovely product that delivers results! This one product has replaced my moisturizer and serums and simplified my routine a great deal! Love all my RS products!

    I’ve recently transitioned to a more natural skin care regimen and after testing more serums than I want to admit and paying top dollar for the “game changing” claims that are nothing more than an eau de perfum for your face, I have finally found, as all of the reviews like to call it, my liquid gold! This serum delivers on every promise and I can visibly see the difference with every application. Lines have softened, skin tone is more even, and hormonal breakouts are a thing of the past. I’m not one to take the time out to review but I know Root Science is a small family run company, and they send the sweetest letters with every order, so a small gesture, like a review, matters in the grand scheme of things. Thank you Team RS, you guys are just as fabulous as your products!

    I can’t say enough about this serum. The moment I received it as a sample and I instantly feel in love with not only how it made my skin feel but the smell. It gives my skin a healthy glow and the texture is so soft. I thank you from the bottom of my heart, I’ve been looking so long for this liquid gold and all along it’s been here and I’m so thankful.
    I highly so highly recommend this wonderful serum. I promise you won’t be disappointed.
    Thank you so much.

    This product is amazing. Ever since I’ve started to incorporate this into my skincare routine faithfully I started to wear significantly less makeup. It wears amazing alone or under makeup. Most people would call me a hard core beauty addict. Instead of buying a new pair of shoes or a killer outfit I would shop for skincare (which is crazy to my colleagues since I work in high fashion). As most people with skincare woes there is always a search for a product that will bring the confidence that is needed. This product brought me that confidence by giving me healthy, happy and glowing skin! No more sephora trips for me (unless they start to carry root science)!

    I am hopelessly in love with this serum. It has completely changed the health of my skin. I have less breakouts and dryness and a more even, glowing skin tone. I also use the Beauty Bar, the Face Scrub and the Reborn and Detox masks, all of which are incredible. This recovering green beauty addict is now officially a Root Science addict! Thank you Gigja for making such beautiful and effective products!

    I use this serum right after cleansing, while my skin is slightly damp. My skin feels so soft and looks noticeably more plump. I love the scent of this serum so much I find myself re-applying it throughout the day in small amounts around wrinkle prone areas such as my under eyes just to get a sniff!

  14. Rated 5 out of 5


    Best serum I’ve come across in a long time! Scent is not overpowering, sweet with an undertone of earthy and the texture is spot on! The oil is not too light or too heavy yet super hydrating. I’ve used it for 2 months now and my skin is loving it as my monthly breakouts have decreased and my skin tone is noticeably more even and healthy. A+ product!

    Where have you been my whole life?! I’m a self proclaimed green beauty addict so it takes a lot for me to fall in love and for it to last! My skin has been transformed after using the serum along with the reborn mask, beauty bar and face scrub for the last few months. I started with the detox kit and have since purchased the spa kit. I love the kits as they cover all my skin care needs without getting lost in a maze of products. Thank you for making amazing products and please don’t ever stop!

    I was very happy with my skin care routine when a friend suggested I try the sample of the youth serum…the sample lasted 2 weeks and I was hooked. I didn’t want to go back to my old moisturizer while I waited for my bottle to be delivered. It feels weird at first to use an oil instead of a lotion but I got used to it quickly. I put this on first and then I use a BB cream over it for coverage and SPF and I have never gotten more compliments on my skin!

    Fell in love with one use! The smell is intoxicating! I use this day and night and my skin literally drinks the oil! My skin looks and feels AMAZING!. I’ve had this one bottle for over 2 months now and i still have about half left, this really does go a long way. I need only one pump for my entire face, including my under eyes.

    I have completely rid my cabinets of everything I had been using for my face, including what my dermatologist recommended to me and began using the RS Youth Serum only. In the past two weeks I had two friends comment that my skin looks really great !~ I too see the difference when I awake in the morning. My skin doesn’t look tired, it has a healthy glow to it. I am very pleased to have found a product that I truly believe in and now Root Science is a part of my everyday life. Thank you for the time, care and commitment to creating a product I can truly trust.

    What an amazing product! My skin is visibly smoother and healthier now (and I only been using it for a month). I refuse to go back to any other products after trying this serum. Love, love, love it!!

    Absolutely ADDICTED to this product! Thankful that you send a sample before purchase – its like gold in my house. I cannot go without it now. I not only use it on my face but I also started using it on the eczema on my hands. It fixes the bleeding cracked skin on my hands within 24 hours… something my prescription medication used to take at least 7 days to do. My manicurist even mentioned how much better the skin on my hands was.
    LOVE that its organic as well. So happy to have heard about this product. Liquid gold ! Kris Ann

    This serum was my very first product with RS and it got me hooked! You really only need 1 or 2 pumps and its enough to cover your face and your skin just drinks up! I ordered a sample and then the bottle and that was almost three months ago and I still have a small amount of product left! And I’ve spent the big bucks on tiny bottles of face lotion that didn’t last this long. I love the value of this product and the handcrafted care that goes into it.

  22. Rated 5 out of 5


    I have extremely sensitive skin so I’ve gone to great lengths to find a product that doesn’t irritate my skin. I ordered a sample of RS Youth Serum and knew immediately this was gold in a bottle! No alcohol, no irritating fragrance, and all organic ingredients! It’s was almost too good to be true! My order was made to order, the batch date handwritten! I never imagined my skin care products would be made to order, with fresh ingredients! I can never go back to buying a moisturizer off a shelf again! I’m a super fan Root Science!

    Love Love Love this moisturizer! I’ve used a number of different organic/natural products out there and none compare! My skin literally drinks this stuff and the results are amazing! It’s like a facial in a bottle! Highly recommend!

    I’ve had instant results and I could not be happier with not only the product but also the amazing customer service from Root Science! This serum is light in texture and absorbs into my skin very quickly, which is what I need when I’m running out the house in the morning. My complexion is smooth, even and my skin stays hydrated throughout the day. THANK YOU A THOUSAND TIMES OVER AND OVER!!
