Booster powder with 10% niacinamide for balanced skin
In recent years, niacinamide has become one of the most sought-after ingredients in modern skincare — rightly so, given its effects on skin tone, sebum regulation, barrier support, and pigment control. The problem for many lies in the choice: ready-made serums often have a fixed, sometimes too low concentration, while pure powder formulas rarely exist. Those who want to maximize the benefits of niacinamide without changing their entire routine therefore need a booster that adapts to existing products.
Cosmedix B Complex is exactly such a booster. The lightweight, silky powder contains 10% niacinamide combined with biotin, dehydrated coconut water, yogurt powder, and inulin — a prebiotic ingredient. By mixing a few 'shakes' of the powder into your regular serum or moisturizer, you get a high concentration of niacinamide and a microbiome-friendly boost in one application without having to change your routine. An innovative product in 'mixing crystal' form that is rare in skincare lines.

Active ingredients
10% Niacinamide (vitamin B3): The core ingredient and at a remarkably high concentration. Niacinamide is one of the most researched skincare ingredients and works on multiple fronts simultaneously: it regulates sebum production, strengthens the skin barrier, reduces the visibility of pigmentation spots by blocking pigment transfer, and soothes redness. At 10% concentration, it delivers targeted action for those who want visible results — a higher dose than in most classic moisturizers.
Biotin (vitamin B7): A lesser-known but important B vitamin for the skin. Supports cellular metabolism and helps maintain a healthy skin barrier. Works synergistically with niacinamide in a B-complex approach.
Dehydrated coconut water (Cocos Nucifera Liquid Endosperm): An innovative ingredient — coconut water dried into powder form — that hydrates the skin and helps purify. Provides minerals and amino acids that nourish the skin without weighing it down.
D-trehalose: A natural sugar known in science as a 'survival molecule.' It enables the skin to retain moisture under harsh conditions — dry air conditioning, cold wind — making it a valuable addition to a product mixed with other serums or creams.
Yogurt powder: An ingredient with natural milk acids and skin-friendly properties. Helps soothe, balance, and contribute to a smoother appearance. An ingredient long valued in Asian beauty tradition.
Inulin: A prebiotic ingredient that nourishes the natural skin microbiome. The microbiome — the community of billions of bacteria on the skin — forms the first line of defense against impurities and environmental damage. Inulin actively supports this balance.
Tapioca starch and maltodextrin: Plant-based base ingredients that give the powder its silky texture and ensure it dissolves effortlessly into other products without clumps or grains.
Capryloyl Glycine: An amino acid derivative with mild antimicrobial action that helps balance the microbiome and keeps the skin in equilibrium.

Frequently asked questions
How does a booster powder actually work?
A booster powder is a concentrated form of active ingredients that you add to another product (serum, cream, SPF) at the time of application. Unlike a ready-made serum, you can control the dosage yourself — more powder for a stronger effect, less for a lighter boost. The powder formula also has a longer shelf life because the active ingredients are only activated upon contact with moisture, which prevents oxidation and degradation.
How much B Complex should I use per application?
Cosmedix recommends 'a few shakes' — typically two to three short shakes of the bottle, which corresponds to about 1/8 teaspoon. This is enough for the entire face, whether mixed with serum or moisturizer. When used on face and neck, you can add a little more. For those experimenting: start with less and gradually increase to the amount that shows visible results.
Which Cosmedix product works best with B Complex?
Cosmedix itself recommends combining with Affirm Antioxidant Firming Serum for maximum effect. Other excellent combinations: BrillianCy Face Oil for brightening, Surge Hyaluronic Acid Booster for extra hydration, Cell ID for anti-aging, or Hydrate+ SPF for a simple morning routine. The powder blends effortlessly with almost all aqueous or cream formulas.
How long does 6g last with daily use?
With daily use (one application per day), the jar usually lasts two to three months. Using it morning and evening shortens this to about one and a half months. Although 6g seems small, the powder concentration is so high that only a fraction per application is needed.
Is B Complex suitable for sensitive skin?
Especially suitable. Niacinamide is known as one of the most tolerable active ingredients in cosmetics and has a calming effect on redness and sensitivity. The absence of retinol, salicylic acid, or fragrance also makes B Complex a safe choice for reactive skin. However, when in doubt, do a patch test on the neck before introducing it into your daily routine.
Can I use B Complex during pregnancy or breastfeeding?
Yes. The formula contains no retinoids, salicylic acid, or other ingredients discouraged during these periods. Niacinamide is one of the most widely accepted anti-aging and brightening ingredients during pregnancy and breastfeeding. B Complex is therefore an excellent choice for those seeking an effective booster without concerns during this phase.
Can I combine B Complex with other active ingredients like retinol or vitamin C?
Yes. Niacinamide is known for its excellent compatibility with other actives. In the morning: B Complex mixed with your vitamin C serum (such as Simply Brilliant or BrillianCy) followed by SPF. In the evening: B Complex mixed into your retinol product (Define, Refine, Serum 16) — niacinamide even soothes the possible sensitivity caused by retinol.
Does the powder really dissolve completely in my serum?
Yes, if well mixed. The fine texture based on tapioca starch and maltodextrin is specifically designed for optimal solubility in both aqueous and oily products. First squeeze the serum into your palm, then add the powder and mix thoroughly with your fingers until the texture feels homogeneous. When in doubt: knead a little more — a grain here and there is harmless but not ideal for the skin.
