The Key Natural & Organic Ingredients


Also known as Vitamin B3, it is a unique skin-restoring ingredient that offers numerous benefits for skin, including its ability to help improve uneven skin tone, reduce hyperpigmentation and enlarged pores. It also strengthens and restores weakened skin barriers.


A beautiful emollient that helps prevent moisture loss and restores the skin from dehydration. It is also an antioxidant and assists skin’ supportive elements.

Hyaluronic Acid:

The most famous humectant, well-known for its ability to help the skin retain water and moisture. It also supports the skin’s microbiome.

Salicylic Acid:

It is a Beta Hydroxy Acid that exfoliates by dissolving the bonds that hold the dead cells to skin’s surface. Salicylic Acid is oil soluble, meaning it can penetrate the pore allowing an in- depth cleanse. This makes it especially effective for reducing inflammation, redness and breakouts.

Centella Asiatica:

It has multiple benefits for the skin thanks to its active compounds, including calming and anti-inflammatory properties. It is also a good hydrating ingredient to soothe compromised skin barriers.

Buy this!!!

I have been using this serum for a couple of weeks and my skin feels so soothed, my rough texture has improved dramatically, and none of my blemishes are painful! The formulation is well balanced and it doesn’t irritate my skin at all. I recommend this product. I look forward to trying other stuff from this brand. FABULOUS.

- Christine


It’s definitely doing some magic

My skin tone became much more even and my nose and forehead less oily – I have combination skin. It also helped to reduce the redness. It is lightweight yet hydrating on the skin. I have just ordered a second bottle and plan to be ordering a third once I run out.

- Rachel


Porcelain skin

I absolutely love this Niacinamide Serum. It visibly brightened my skin while also keeping excess sebum and blemishes at bay – I believe it is the combination of Niacinamide and Salicylic Acid. I’ve struggled with post-blemish marks, oiliness, and breakouts for a long time and I’m so happy I found this product.

- Frederique


Just perfection

It made my skin literally velvety soft! It provides moisture in the dry areas and balances sebum production in the oily areas! How do you do that?!?!! It is helping with my uneven skin while also clearing up breakouts. I all honesty, WOW!

- Anna


Must have for clearer skin!

This serum clears redness, minimizes pores, smoothens bumpy texture and calms crazy breakouts. My skin is sensitive skin and I have not experienced any irritation. Well done. I will be a returned customer.

How To Apply

Step 1 of 5

Cleanse your face, neck and décolleté for at least 30 seconds with a facial wash that cleanses in-depth your skin while also supporting your barrier. Kleem Organics Pro-Collagen Facial Cleanser is recommended.

Use lukewarm water to cleanse your skin. The temperature of water is crucial to protect your skin barrier and keeping it resilient. Hot water can cause a heightened level of skin sensitivity and dry out your skin, stripping it of necessary oils. Cold water is surely better that steaming hot water but still not the best option as it can tighten pores and possibly trap dirt and debris not allowing a correct cleanse.

How To Apply

Step 2 of 5

Apply your toner as it helps remove any residue after cleansing and it preps your skin for the next steps. Furthermore, based on the type of toner, it also helps to hydrate/detox or soothe your skin. Choose a milky textured toner if your skin is dry/dehydrated. Choose a light/watery texture toner if your skin is oily/acne prone.

How To Apply

Step 3 of 5

Pump 2 or 3 drops of Niacinamide Booster onto your finger tips and then pat them delicately on slightly damp skin. This will ensure to get the utmost efficacy and will encourage the serum to penetrate better into the deeper layers of the skin.

How To Apply

Step 4 of 5

Let the Niacinamide Booster absorb fully before applying your next skincare products. If you are layering multiple serums, remember to apply first the one with the thinnest consistency following up with the one with thicker consistency.

How To Apply

Step 5 of 5

You can now apply your Eye Cream, Moisturizer, Spf.

Kleem Organics Firming Eye Cream and Kleem Organics Retinol Moisturizer are recommended.

Include your Kleem Organics Retinol Moisturizer in your night skincare routine.
