  • Full Ingredients List



Kleem Organics Vitamin C Serum is formulated to fight the look of dullness, uneven skin tone and hyperpigmentation at the source, while diminishing the signs of premature aging. Skin looks firmer and plumper, as youthful skin bounce is restored and the skin barrier is repaired.

Kleem Organics Vitamin C Serum uses the sophisticated Stay-C® 50, which is the most stable form of Vitamin C available. In fact, Vitamin C is highly effective in its pure form, but it can degrade with exposure to oxygen, water and high pH and this is why it is essential to have a form that is more stable and to store it in an airless packaging.

This serum is also enriched with a blend of botanical ingredients such as Hyaluronic Acid and Aloe Vera that are well-known for their significant hydrating properties and anti-aging benefits, including visual improvement in loss of firmness, the appearance of lines and wrinkles, age spots and dullness.


Coping with city life, pollution, stress and general environmental hazards causes the skin to be dull and to lose its natural glow. For those of you who want to get that gorgeous healthful look back, you have found your guardian angel in a bottle. Prep your skin with this highly concentrated Vitamin C serum and be ready to notice an instant shot of skin magic.

  • Repair hero: Helps to protect skin from pollution and other environmental aggressors
  • Youth Booster: Helps to reduce fine lines, wrinkles, age spots and uneven skin tone
  • Baby-Soft Enhancer: significantly improves skin smoothness and overall texture
  • Nourishment Powerhouse: it promotes healthier and more naturally glowing skin

Whether you looking for a brighter complexion, a more even skin tone, protecting your skin from stress and free radicals or reducing the appearance of fine lines, wrinkles or age spots, this highly concentrated Vitamin C Serum will address your concerns and deliver the results your skin deserves.

Liquid Gold

I'm sold, I'm a new convert, but boy I am converted! I was already using Kleem moisturizer, but when I added this, it became a whole new world. The difference in my skin is amazing and I'm 63 and a smoker so my skin was showing abuse. Not anymore. The serum has improved everything, wrinkles, sagging, dk circles, it's woken my face up. I can't think of anything I've used in my life that had made such a drastic difference!

Makes your skin radiate youthfulness and freshness

It is not easy to find a simple and effective product for male skin but this Kleem's Vitamin C Serum is the best I ever had. I use it every day before going to work and under my regular moisturizer (I like Kleem's anti-aging cream). My 79-old mother and my sister love it too. A winner all around!

- Yuri



What an amazing serum. I have dry, sensitive skin and after having used for more than a month I can definitely see the results. My skin seems brighter, more hydrated and I have seen a great reduction in my pores. I have been complemented by many on my skin after using this serum. Very satisfied with this product and would recommend to everyone.

- Samerah


I love this serum so much!!

After one week I could see a difference. Now in week 3 and I am over the moon. After radiotherapy to my head and neck (add age in as well lol) I thought I would be wrinkled for life. This really has given me back my confidence. I am now into my second month on the serum and retinol cream. I cannot believe the change in my skin tone and wrinkles. It out ranks all the other products I have tried by miles in performance and price.

Very Special

I have very fair, sensitive skin. This is clear, not creamy. It goes on smoothly and distributes evenly. It has no sensation on my skin other than soothing coolness: no prickliness, no burning, nothing irritating. It has a beautiful light, natural scent that is perceptible for a short while, then fades as the serum is absorbed. I’m so pleased I’m placing it on auto ship.

How To Apply

Step 1 of 5

Cleanse your face, neck and décolleté with a 5.5 pH level cleanser that restores the skin's barrier and helps keeping your skin hydrated and nourished. (Kleem Organics’ Turmeric and Vitamin C Facial Cleanser is recommended.)

Use lukewarm water in order to melt away pollutants, dirt, sebum and fragrance. The temperature of water is important as cold water can tighten your pores and this can trap bacteria and debris and won't clear out your skin as easily as using warm water. As a consequence, unclean skin will not absorb effectively all your skin care products. On the other hand, hot water causes capillaries to burst, resulting in redness and inflammation.

How To Apply

Step 2 of 5

Apply your toner as it helps to remove any residue of make-up left after cleansing, it also protects your skin, removes chlorine and minerals present in tap water and it increases absorption of your next skin care products.

How To Apply

Step 3 of 5

Dispense one/two drops of our Vitamin C Serum onto your fingertips and rub them lightly together. Gently tap the surface of your cheeks, forehead, chin and neck with your fingers for 30 seconds. Do not stretch, pull or rub the skin. The tapping action encourages the serum to sink fully into the deeper layers of the skin for utmost efficacy.

How To Apply

Step 4 of 5

Let the Vitamin C Serum absorb completely into the skin for a couple of minutes. If you feel any tingling sensations – don’t worry. Tingling is a sign that the bio-active ingredients in our serum are getting to the dermis – where they need to be if they are going to work.

For best results, apply the Vitamin C Serum twice a day, in the morning and evening. If it’s your first time using a Vitamin C based product, start with a once a day or every other day application until your skin has adjusted to the new ingredients before switching to the twice a day application.

How To Apply

Step 5 of 5

You can now apply your eye cream, moisturizer and facial oils. Kleem Organics Peptides Eye Cream and Retinol Moisturizer are recommended.

Face oils give additional emollients that dry or dehydrated skin may need.


Frequently Asked Questions

Yes, the Vitamin C Serum is cruelty free at every stage of production.

Yes, the Vitamin C Serum is vegan-friendly.

The product contains 25% of Vitamin C.

Yes, the concentration of active ingredients, especially Vitamin C in combination with Ferulic Acid which potentiates the effects of Vitamin C, allow the cells to turn over faster and to produce more collagen therefore contributing to clearer and more even skin.

For best results, we suggest to apply the product twice a day in the morning and in the evening before your moisturizer/spf. If you have never used a Vitamin C based serum before, start with a 4/5 times per week application to allow your skin to adjust to the new ingredients.

Sunscreen is fundamental always, regardless of the skin care product you are using, so, yes, absolutely, you need to wear sunscreen after the application. Vitamin C fights against the effect of both UVB which mostly effects the external layers of the ski and UV, which are the most dangerous as they can penetrate deep into the skin cell, altering and destroying collagen, elastin and other skin cellular structures. As UVA can penetrate 30 – 40 times deeper than UVB it is responsible for causing skin aging, hyper pigmentation. On the contrary, UVB is mostly related to sun burn, production of free radicals and skin cancer. The use of a properly-applied sun cream can only stop around 55% of free radicals produced by UV rays. The 45% of free radicals left, responsible for photo-aging can be blocked by the application of the powerful antioxidant vitamin C. Vitamin C doesn’t create a protective shield against the UV rays, since it doesn’t absorb them, instead it neutralizes the dangerous free radicals. This highly beneficial and desirable effect cannot be provided by any solar cream. That’s why it’s so important to use both solar cream and vitamin C serum for best protection.

If this is your first time using active ingredients as Vitamin C in high concentration, you may experience slight dryness and/or slight tingling sensation at the beginning of use. Allow your skin to adjust to them by applying the product only 4/5 times per week before passing to the once-a-day/twice-a-day application.

No, this product is parabens and silicones free.

The Vitamin C Serum has a very delicate citrusy scent deriving from the plant-based ingredients.

The product has a 12 months shelf life from opening.

With regard to rosacea, absolutely. Vitamin C, Vitamin E and Ferulic Acid are rockstar ingredients when it comes to improving this concern.

No, all our products are genderless.

Yes, the bottle can be re-used and recycled too.

We have two sizes of Vitamin C Serum. The smaller one contains 1oz/30ml of product; the larger size contains 1.7oz/50ml of product.

Yes, absolutely.

This very much depends on the improvements you are looking to obtain; for instance, smoother and brighter skin can be achieved after a few days of application, reduction of sun spots and wrinkles take at least a couple of months, improvements in the clarity and overall health of your skin can take from two to six weeks. For more specific answers based on your skin goal, please email us at: customersupport@kleemorganics.com

Yes, usually serums need to be followed by a moisturizer to guarantee your skin with the right amount of hydration it needs. The Vitamin C Serum has a lightweight consistency and delivers actives into the skin. To achieve best results and to keep your skin properly hydrated we do advise to always apply a moisturizer to both “lock-in” the treatment and to create a physical barrier that retains hydration and prevents skin from drying out. Our most felt advise in terms of skin care is: follow what your skin tells you.

Yes, the blend of active ingredients contained in the Vitamin C Serum can work well in conjunction with Retinol, which is an anti-aging powerhouse. Research has shown that a combination of vitamins in cosmetics will provide optimal results—including vitamins A (that is retinol), C, and E. Pairing Retinol and Vitamin C creates a better environment for Retinol by stabilizing it, extending its effectiveness.

Yes, the formulation has been studied to be suitable for sensitive skin too. You may want to do a patch test before and keep in mind that if you have never used a Vitamin C based skin care product before, it is best to start with a 4/5 times per week application until your skin has adapted to the ingredient.

The Vitamin C Serum should be stored in a cool environment (during summer we do suggest to keep the product in the fridge away from high temperatures).

Unless the product arrives damaged or defective, we generally encourage people to apply the product consistently twice a day for a period of 30 days before notifying us about their unsatisfaction. In any case, we are always available for offering our suggestions and support. You can always reach out to us at: customersupport@kleemorganics.com
