Here’s what to know: Niacinamide is generally considered safe when consumed within recommended limits. During pregnancy and breastfeeding, the maximum daily intake is 30 mg for individuals aged 14–18, and 35 mg for those aged 19 and above[1].
This leads to an important question: Does the same apply when it is used in skincare? The answer is not always as straightforward as it seems, especially when factors like absorption, formulation, and skin sensitivity during pregnancy are taken into account.
Niacinamide vs. Niacin
Before diving further, it is important to first clarify what niacinamide actually is and how it differs from niacin.
- Niacin is a water-soluble B vitamin essential for maintaining overall health.
According to Ministry of Health Malaysia, the recommended daily intake of niacin is around 18 mg per day during pregnancy[2], reflecting its importance in supporting maternal health and foetal development.
- Niacinamide (nicotinamide) is a derivative of niacin, produced when there is an excess of niacin in the body.
In modern formulations, niacinamide is commonly used in:
- Skincare products (for acne, pigmentation, sensitivity)
- Dietary supplements (in controlled doses)
Unlike some active skincare ingredients, niacinamide is known for being gentle, non-exfoliating, and non-photosensitising. This characteristic makes it particularly suitable for sensitive skin conditions, including those experienced during pregnancy.
Niacinamide Usage During Pregnancy
Niacinamide is a gentle, non-irritating ingredient known for improving overall skin texture and tone. It offers several clinically supported benefits[3], including:
- Reducing redness and inflammation associated with acne
- Helping to improve the appearance of fine lines and other signs of ageing
- Minimising the appearance of dark spots and uneven pigmentation
This makes it a versatile option for maintaining balanced, healthy-looking skin.
Topical niacinamide is generally regarded as low risk and suitable for use during pregnancy. Dermatological consensus and clinical understanding indicate that:
- It has minimal systemic absorption
- No studies suggest topical use causes harm to the foetus
- It is widely considered safe by skincare experts and dermatologists
Importantly, niacinamide is derived from vitamin B3, a nutrient already recommended during pregnancy for normal metabolic and cellular function. This distinguishes it from certain active ingredients, such as retinoids, which are associated with developmental risks and are typically avoided during pregnancy.
It’s worth noting that during pregnancy and breastfeeding, the skin often becomes more delicate and reactive due to hormonal changes. This makes ingredient safety and tolerability even more important when selecting skincare products.
As with any skincare product, it is advisable to follow usage instructions carefully and consult a healthcare professional before introducing new products, particularly when the skin is more sensitive than usual.
Myths vs. Facts About Using Niacinamide During Pregnancy
Myth 1: All forms of niacinamide are safe without limitation
Fact: The route of use matters
Not all forms of niacinamide carry the same safety profile.
Topical niacinamide:
- Minimal absorption into the bloodstream
- Widely considered safe during pregnancy and breastfeeding
- Suitable for daily use
Oral supplements or high doses:
- May cause side effects such as flushing, liver stress, or blood sugar changes[4]
- Should only be taken under medical supervision
Myth 2: Niacinamide is only suitable for oily skin
Fact: Niacinamide is not limited to oily skin.
While it is well known for helping regulate sebum production, reduce excess shine, and refine the appearance of pores, niacinamide is suitable for all skin types, including dry, sensitive, and combination skin.
Its versatility comes from its ability to support multiple skin functions at once.
Niacinamide helps:
- balance oil levels,
- soothe redness,
- strengthen the skin barrier,
- and improve overall hydration.
This feature makes it particularly beneficial when the skin is experiencing fluctuations, such as during pregnancy.
How to Use Niacinamide Safely During Pregnancy
To ensure optimal safety and effectiveness:
Recommended guidelines
- Use products with 2–5% niacinamide concentration
- Apply once or twice daily as part of a gentle skincare routine
- Pair with hydrating and barrier-supporting ingredients
Best ingredient pairings
Niacinamide works well with other pregnancy-safe ingredients[5] such as:
- Hyaluronic acid – for hydration
- Ceramides – for barrier repair
- Vitamin C – for antioxidant protection
- Panthenol and glycerin – for soothing and moisture retention
Avoid combining with strong actives like retinoids or harsh exfoliating acids, which are generally not recommended during pregnancy.
