Oral zinc and skin clarity
Clinical research has examined the role of zinc in skin health and in supporting the body’s normal inflammatory response. Research and reviews indicate that zinc is involved in the regulation of immune activity and inflammatory processes, suggesting it may help support balanced inflammatory function.*
In a controlled study of healthy individuals, zinc supplementation was associated with changes in skin-surface sebum levels, suggesting it may play a role in supporting balanced skin oil levels. Zinc is also a foundational trace element involved in skin renewal, contributing to enzymatic and structural processes that support overall skin health.*
Oral niacinamide and skin barrier support
Clinical research has evaluated oral nicotinamide (vitamin B3) and its effects on skin physiology. In a randomized controlled study, nicotinamide supplementation was associated with reduced transepidermal water loss (TEWL), a measure of skin barrier function, suggesting it may help support the skin’s ability to retain moisture.*

Is it safe to take while using niacinamide and zinc topical products?
Yes. Because topical skincare stays primarily on the skin's surface it has negligible absorption into the bloodstream. Our formula is designed with dosages so that it can be used as a core part of your daily skincare together with your existing routine.
How long does it take to see results?
Inner skincare requires consistency. Internal support works alongside your skin's natural renewal cycle, and we recommend a minimum of 90 days of consistent daily use (two capsules a day) to see optimal improvements.
Is it right for me?
If your goal is to support a clear complexion, calm the appearance of the skin, refine texture, and moisture balance — and you want the benefits of niacinamide and zinc in your skincare routine in ingestible form without topical characteristics, this formulation is designed for you. It is the ideal supplement for anyone looking to elevate their skincare routine without sacrificing what your skin could benefit from.
Why is it recommended to take with food?
We use safe but effective doses of active ingredients, including 30mg of elemental zinc. While we specifically selected Zinc Bisglycinate Chelate to be gentler on the stomach, taking any potent zinc supplement on a completely empty stomach can cause mild, temporary nausea. Taking your capsules with or immediately after a meal ensures optimal absorption and digestive comfort.
What is a "niacin flush"?
A "niacin flush" is a common physical reaction to high doses of standard Vitamin B3 (nicotinic acid), which temporarily expands blood vessels and leaves the skin feeling hot, red, and itchy. This is not a concern with our formulation as we strictly use niacinamide — a completely non-flushing form of Vitamin B3. This ensures you receive all the clinical, barrier-supporting benefits without any of the uncomfortable heat or redness.
Is this vegan and cruelty-free?
Yes. Paucal is 100% vegan, cruelty-free, and formulated without gluten, major allergens, or synthetic fillers.
