EXPERIENCE

A serum that helps your skin find its balance

  • Product

    Our lightweight Vitamin B3 serum absorbs quickly into the skin, delivering hydration without feeling heavy or sticky. The aloe-based formula feels soothing and comfortable, making it ideal for sensitive, reactive, or blemish-prone skin.

    The natural golden color comes from our blend of botanical extracts, while plant peptides and comfrey work alongside 12% Vitamin B3 to support calmer, healthier-looking skin.

  • What to expect

    Short term

    Your skin feels calm, hydrated, and comfortable without heaviness or irritation.

    Over time

    With consistent use, you may notice less visible redness, smoother texture, a more even complexion, and skin that feels stronger and more resilient.

    If you have sensitive or reactive skin

    Many high-strength treatments can cause stinging or dryness. This formula is designed to provide the benefits of 12% niacinamide while remaining gentle enough for daily use.

  • Use

    Apply a few drops to clean skin morning or evening after cleansing.

    Gently massage into the face and neck until absorbed.

    Follow with moisturizer. During the day, finish with sunscreen to help protect against UV exposure and support long-term skin health.

    Use morning and night as your daily targeted treatment for redness, uneven tone, texture, and skin barrier support.

APPROACH

Healthy skin starts with a stronger barrier

Many common skin concerns - including redness, irritation, uneven tone, and blemishes - can be linked to a weakened or stressed skin barrier.

While many products focus on aggressively correcting these symptoms, healthy skin starts with restoring balance. Niacinamide helps support your skin’s natural barrier by encouraging the production of essential lipids, allowing it to retain moisture and better defend itself from daily stress.

Our formula combines 12% Vitamin B3 with soothing botanicals and plant peptides to calm irritation, improve texture, and support a healthier, more resilient complexion over time.

Strengthens your skin barrier

Vitamin B3 supports natural ceramide production, helping your skin hold moisture, stay balanced, and better resist irritation.

Calms sensitive, reactive skin

Comfrey, aloe, and botanical extracts help soothe visible redness and support a calmer, more comfortable complexion.

Improves tone and texture

Plant peptides and niacinamide work together to help smooth skin, reduce the appearance of pores, and promote a more even-looking complexion.

I also use this product along with the Vitamin C serum on my hands

I also use this product along with the Vitamin C serum on my hands. Love it! I recently saw an add for a hand cream with bakuchiol, Vit B3 and Vit C. Instead of buying the hand cream, I decided to just use the serums on my hands every night. I just use one drop of each serum on the top of each hand. I love it!

Just Amazing

With rosacea-prone skin, I’m always skeptical about trying new products. But the OM Botanical Niacinamide serum didn’t trigger a single flare-up. In fact, my redness has visibly calmed down, and my skin texture has improved dramatically. Love that it's gluten free and alcohol free too.

Ordering my 3rd bottle...

I love this Vitamin B3 Serum! I use it every morning as a light moisturizer. I'm 56 so I need hydration after washing my face, but regular moisturizers are too heavy for me. And I can't use oils because they make my face too shiny (hello large pores!). This Serum does the trick. My face doesn't feel tight and I can wear makeup on top if I like. My 2 favorite Om Botanical products are this Serum & the Magnesium Body Lotion.

Amazing Product. I bought it at the Conscious Life Expo in LA. Been using it daily. It definitely improves my skin within 3 days. Just made another order.

Has lightened my hyper pigmentation and reduced the size of my pores. Saw a difference in just a few days and am continuing to see changes.

I used this product before and really like it. However recently the container switched from plastic pump to glass dropper. I travel often so the glass dropper doesn't work well for me. It is heavier, breakable and harder to dispense the liquid.

This product is so smooth and refreshing to put on my face. It has a wonderful light texture and absorbs quickly. The scent is fresh and light. Absolutely love this!

This toner was shipped as a freebie to my order. And I'm delighted; I'll order it from now on! The product is very concentrate so it takes very little to cover my face and neck. It smooths and tightens gently while leaving my skin soft to the touch. I shopped for a line of skin care products that are plant based, environmentally sensitive, and made in the US. OM Botanical met those criteria, and I was delighted to learn they're based in my own back yard! Now I shop local too!
