What Is Niacinamide Used For?
Niacinamide, also called nicotinamide, is the water-soluble, active form of vitamin B3. DermNet New Zealand notes that it is used in many topical products, including sunscreens and cosmetic products.
- Barrier and moisture: DermNet states that topical nicotinamide can improve skin barrier function by decreasing water loss through the epidermis, which increases hydration.
- Tone: DermNet reports studies in which hyperpigmented spots and red blotchiness improved.
- Oil balance: DermNet states that nicotinamide also reduces facial sebum production.
- Tolerability: DermNet describes topical nicotinamide as generally well tolerated.
These points describe niacinamide in general. They are not test results for this specific serum.

What Does 10% Niacinamide Mean?
A 10 percent niacinamide serum contains 10 g of niacinamide in every 100 g of product. Ingredients present above 1% must be listed in descending order of weight, and niacinamide appears second on this serum’s INCI list, directly after water (Aqua). That order is consistent with the 10% stated on the front of the pack.

How to Use It and How Often
- Cleanse the face and neck and pat the skin dry.
- Apply a few drops to clean, dry skin on the face and neck.
- Gently press into the skin until absorbed.
- Use once daily.
- Use SPF protection during the day.
- Optional: Herbalife suggests gently massaging the serum in with its White Jade Gua Sha Tool.
The label says the serum is for external use only, should be kept out of reach of children, should not touch the eyes, and may cause irritation on initial use. Many people patch-test a small area first. DermNet notes for topical nicotinamide in general that use can be reduced if the skin becomes too dry.
Who Is It Suitable For?
Herbalife states that the serum is suitable for diverse skin types and for use under makeup. It is intended for adults who want a daily serum that supports the skin barrier and a bright-looking, even-looking complexion. Anyone with a skin condition, a known allergy or questions about suitability can ask a pharmacist or a doctor before use.

A serum normally sits between cleansing and moisturising:
- Morning: cleanse, serum, moisturiser, SPF
- Evening: cleanse, serum, moisturiser
Because the directions allow one application a day, either slot works. DermNet states that nicotinamide does not work as a sunscreen, so SPF remains a separate step.
