Do you have oily skin? This product is for you.

Most oily skin comes down to one root cause: overproduction of sebum. And when your skin produces too much oil, it shows up as real, visible problems — acne and pimples, whiteheads, enlarged and more visible pores, shiny or greasy-looking skin, dull skin tone, rough or bumpy texture, and redness.

If you're struggling with any of these, this is for you.

Here's what the NVBS does:
It is a lightweight, fast-absorbing serum that is built around niacinamide, which helps regulate excess oil production, refine the look of enlarged pores, and calm redness.

It's paired with 3-O-Ethyl Ascorbic Acid, a stable form of vitamin C that helps brighten dull skin tone and even out texture, while Panthenol (vitamin B5) soothes redness and strengthens your skin barrier so it can better manage oil on its own.

Glycerin draws in lightweight hydration without adding grease or heaviness, keeping the formula fast-absorbing with no residue.

Collapsible content

WHAT'S INSIDE AND WHY?

Niacinamide (Vitamin B3): The core of this formula. Helps regulate excess oil production, visibly minimize the appearance of enlarged pores, calm redness, and support a more even, balanced complexion over time.

Vitamin C (3-O-Ethyl Ascorbic Acid): A stable form of Vitamin C that actually reaches your skin without breaking down. Helps brighten dull uneven skin tone and supports your skin's natural defence against daily environmental stress.

Panthenol (Pro-Vitamin B5): Absorbs deep into the skin to restore lightweight moisture, soothe irritation, and soften rough or bumpy texture — leaving skin noticeably calmer and more comfortable from day one.

Every ingredient in this bottle has a reason to be here. Nothing more, nothing less.

Full Ingredient List: Water (Aqua), Glycerin, 3-O-Ethyl Ascorbic Acid, Niacinamide, Panthenol, 1,2-Hexanediol, Xanthan Gum, Sodium Citrate, Sodium Phytate, Polysorbate-20, Citric Acid

THE 28 DAY DEVELOPMENT JOURNEY

Because your skin follows a natural 28-day renewal cycle, results build with consistent use:

  • Day 1: An immediate surge of hydration and a calmer, more balanced complexion.
  • Day 14: Visible improvement in oil balance and a more refined skin texture.
  • Day 28: A stronger skin barrier and a noticeably brighter, more uniform skin tone.

Your skin is always developing. This is where that development begins.

HOW TO USE

  1. Apply: 2–3 drops to clean skin, morning and/or evening.
  2. Massage: Gently press into the face and neck until fully absorbed.
  3. Follow: With your favourite moisturizer. Always apply SPF during the day.

New to niacinamide? Start every other day for the first two weeks to give your skin time to adjust. Most people tolerate it well — we just believe in giving your skin the time it needs to develop.

WHO IT MAY NOT BE FOR

  • If you have a confirmed niacinamide sensitivity: Some people experience initial purging or sensitivity when introducing niacinamide into their routine. If you've previously reacted to niacinamide we recommend consulting your dermatologist before use.

  • If you're looking for instant results: This serum works with your skin's natural 28-day renewal cycle. If you're looking for an overnight fix this isn't it — but if you're ready to commit to your skin's development, the results are real.

  • If your skin is currently broken out or compromised: We recommend waiting until your skin has settled before introducing any new active ingredients including this serum.

We'd rather tell you upfront than have you disappointed. That's what skin development actually looks like — honest, informed, and consistent.

Research

The Science Behind NVBS

Clinical research supporting our formulation

Oily Skin & Acne Connection

A cross-sectional study of 419 people in the Jazan Region, Saudi Arabia, found that more than half of participants (66.8%) had acne — and those with oily skin were twice as likely to have acne as those with dry skin.


Severity Linked to Skin Type

A study of medical students found an acne prevalence of 80.9%, with skin type significantly linked to both the likelihood and severity of acne — those with oilier skin experienced more severe breakouts.


Sebum as a Key Driver

Two South Korean studies comparing women and men with and without acne found that participants with acne consistently had higher sebum (oil) levels than those without — reinforcing oil production as a key driver of breakouts, not just a side effect of them.


Pore Size & Oil Production

Separate research on facial pores found that sebum output was the strongest predictor of enlarged pore size — more oil, more visible pores.


Niacinamide at 5%

A landmark study by Bissett et al., published in Dermatologic Surgery, tested 5% niacinamide over 12 weeks and found statistically significant improvements in pore appearance, skin texture, and fine lines. Research also shows 5% is where niacinamide delivers the majority of its clinical benefit — sebum control, pore refinement, and calming inflammation — while remaining gentle enough for daily use.

FAQ's

How Long Until You Notice a Difference?

Your skin follows a natural 28-day renewal cycle — meaning real, visible results take time to build. Here's what most people experience:

  • Day 1: Skin feels immediately more hydrated and calm
  • Day 14: Texture starts to improve and pores look more refined
  • Day 28: Skin tone is visibly more even, brighter, and clearer

Consistency is everything. 2–3 drops every day is what gets you there.

Is Déve Suitable for Sensitive Skin?

Yes — the formula is designed to be gentle enough for daily use on all skin types including sensitive skin.

However if you have a known sensitivity to niacinamide we recommend starting every other day for the first two weeks to give your skin time to adjust. If you're unsure consult your dermatologist before use.

Can I use this with my existing skincare products?

Yes. The Déve Vitamin Boost Serum is designed to work as part of your existing routine. Apply 2–3 drops to clean skin before your moisturizer. Always follow with SPF during the day.

One thing to be mindful of — if you're currently using a retinol or strong exfoliant introduce this serum gradually rather than all at once to avoid over-activing your skin.

What makes this different from other niacinamide serums?

Most niacinamide serums either use an ineffective concentration or pack so many ingredients in that nothing works at its optimal dose.

The Déve Vitamin Boost Serum uses 5% Niacinamide — the clinically studied concentration — alongside a stable form of Vitamin C that doesn't degrade in the bottle, and Vitamin B5 to support everything your barrier needs to stay calm and receptive.

Three vitamins. Nothing unnecessary. And we explain every single ingredient so you always know exactly what you're putting on your skin and why..

How long does one bottle last?

One 30ml bottle typically lasts 4–6 weeks with daily use of 2–3 drops morning and evening. With once daily use it lasts closer to 8 weeks.
