Is 50mg niacinamide enough orally?

Yes. Oral niacinamide works differently from topical, it's converted to NAD+ systemically. You don't need the same concentrations as a serum because it's working at the cellular level.

Can I use both a niacinamide serum AND take these?

That's exactly the idea. Topical niacinamide handles surface-level pore refinement. Oral niacinamide supports the deeper barrier repair. They complement each other.

I have sensitive skin—is this safe?

Oral niacinamide is generally very well tolerated. Unlike high-concentration topical niacinamide which can sometimes irritate sensitive skin, oral B3 works gently from within.

Which Flexies product has niacinamide?

Our Tanning Gummies contain 50mg niacinamide per serve, plus astaxanthin and beta carotene for additional skin benefits.

your serum needs backup

Topical niacinamide tackles pores and redness on the surface. Oral niacinamide repairs your skin barrier from within.

The surface fix

Your niacinamide serum is great at reducing visible pores and calming redness on contact. But it can't repair the deeper barrier dysfunction causing those issues in the first place.

The root cause

When your skin barrier is compromised from within, it doesn't matter how much you apply topically—moisture escapes, irritants get in, and your skin stays reactive.

The stack

Oral niacinamide supports NAD+ production for cellular repair systemically. Your serum handles the surface. Together: barrier resilience from every direction.

why these work

the science, simplified

Topical niacinamide reduces sebum production and minimises pore appearance on the skin surface. But barrier repair requires NAD+ production, which oral niacinamide (vitamin B3) supports from within.

NAD+ is essential for cellular energy and DNA repair. As we age, NAD+ levels decline. Oral niacinamide provides the precursor your cells need to maintain repair capacity.

Combining topical niacinamide (pore refinement, redness reduction) with oral niacinamide (barrier repair, cellular energy) creates a comprehensive skin clarity protocol.

your barrier repair

Skin barrier repair takes consistency. Here's what to expect.

PHASE 01

Week 1–2

Cellular Fuel

NAD+ levels begin rising. Your skin's repair machinery gets the fuel it's been missing.

NAD+ building

PHASE 02

Week 3–6

Barrier Repair

Skin feels less reactive. Your serum seems to absorb better because the barrier underneath is stronger.

Less reactivity

PHASE 03

Week 6–10

Clear & Calm

Visibly clearer, calmer skin. Pores refined from both directions. Your barrier is actually doing its job.
