Amara G.
I have deep brown skin and hyperpigmentation that's tortured me for years. I've tried countless 'brightening' serums that did nothing for my complexion. LARITZA Niacinamide is the first serum that actually acted. In 5 weeks, my spots are noticeably reduced. I'm stunned.

It wasn't your hormones. It was your melanocytes — and they just needed clearer signals.
— Dr. Nadia Osei, Dermatologist
Hyperpigmentation in deeper skin tones is one of the most under-treated dermatological issues in the US market. Most 'brightening' products use insufficient concentrations of actives — or worse, dangerous ingredients. Niacinamide at 10% is one of the few molecules scientifically proven to inhibit the transfer of melanosomes to the skin surface — without disrupting natural pigment production or causing the rebound hyperpigmentation that hydroquinone can trigger.
Dermatologists increasingly recommend targeted clinical actives over broad multi-ingredient formulas.
Dermatologist RecommendedWhat's Inside Niacinamide Serum 10%
Targeted ingredients working together for your skin.
Niacinamide 10%
Niacinamide (Vitamin B3) acts at a unique cellular level: it interrupts the transfer of melanosomes — the packets of melanin — between melanocytes and keratinocytes. In plain terms, your dark spots stop being 'fed' with new pigment. At 10%, this concentration is clinically validated for maximum efficacy — far above the 2–5% you find in most products. We publish the exact percentage on our label because we have nothing to hide.
Your Journey to Clearer, Healthier Skin
Thousands of women have seen these changes. Here's what to expect.
Things Start To Even Out
Your skin feels more even-toned at the surface. New post-acne marks fade faster than before. Dullness you didn't even fully notice starts lifting. This isn't your imagination — niacinamide starts working at the cellular level in the first 2 weeks. Some customers notice pore refinement almost immediately.
You Feel The Difference
Existing dark spots have visibly reduced. Pores look tighter in natural light. Your overall tone is more uniform — visible even without makeup. Customers who photograph their progress report this is the week the photos start telling the real story.
The Skin You've Always Wanted
Your most stubborn dark spots are significantly faded. Your skin tone is the most even it's ever been. People notice. You notice in the mirror. Some customers share their before/after with their community because the results feel too good not to share. You've finally found what works — and you have the photos to prove it.

I documented every week and the results speak for themselves
I was a total skeptic. I took photos on Day 1 and tracked every week. Week 4: I can clearly see the difference on my post-acne marks. Week 8: some have almost disappeared. I shared my progression in r/SkincareAddiction and people couldn't believe it.

The confidence I've been looking for for 10 years
My dark spots followed me from two pregnancies. I tried products with hydroquinone but stopped — I was scared of long-term effects. LARITZA with no hydroquinone gave me confidence, and the results followed. I wish I'd found this sooner.

Follow these simple steps for best results
After Cleansing — Morning & Evening
Cleanse your face with Charcoal Cleanser (or your current cleanser). Pat gently — leave skin slightly damp. Slightly damp skin enhances absorption of the niacinamide significantly.
3–4 Drops — Pat, Don't Rub
Dispense 3–4 drops onto your palm. Warm slightly between fingers. Apply by gently patting onto your entire face, pressing into hyperpigmented areas. Patting (not rubbing) prevents stretching the skin.
Wait 2 Minutes, Then SPF
Allow 2–3 minutes for the serum to absorb before applying moisturizer. In the morning, always finish with SPF 30+. Without sun protection, UV triggers melanin faster than the serum can inhibit it — and your results will be limited. SPF is non-negotiable.

Effective on very deep skin tone
Ebony skin, severe hyperpigmentation. I thought I'd never find something formulated for me. LARITZA Niacinamide surprised me. Deep spots take longer, but the difference is real and measurable. I'm on month 3 and still improving.

At 46, I'm getting my skin back
I thought age spots were permanent. My derm told me 'it's normal with age.' LARITZA proved otherwise. My sun spots have reduced significantly in 2 months. I feel like I have my face back.

Niacinamide Serum 10%Frequently Asked Questions
Find answers about our products, shipping and returns.
First improvements typically appear in 2–4 weeks. Most significant results on persistent spots come at 8–12 weeks of consistent daily use. Patience + SPF = results.
This serum was formulated with deeper skin tones as a priority. Niacinamide is one of the few actives proven safe and effective across all Fitzpatrick phototypes without rebound hyperpigmentation risk.
Our serum already contains a stabilized Vitamin C form. We don't recommend layering another Vitamin C (especially pure ascorbic acid) — it can create instability. Use our serum alone for this step.
Yes. Non-negotiable. Apply SPF 30+ every morning. Without it, UV produces melanin faster than the serum can inhibit it — and your results will be significantly limited.
Niacinamide is generally considered pregnancy-safe, but always consult your OB or dermatologist before adding any new skincare during pregnancy.
Yes — morning and evening use optimizes results. The serum is formulated for twice-daily application.
30-day full refund, no questions asked.
Yes, on orders of $50 or more.
