Routine step
Serum step after cleansing, toning and exfoliating, before emulsions and creams.
Why it works
B-Bomb is a light, hydrating 10% niacinamide serum designed to support pores, oiliness, blemish-prone skin and uneven tone without drying out the skin.
Pore appearance support
10% niacinamide helps improve the look of enlarged pores. Skin looks smoother, more refined and more balanced.
Oil-balancing support
Zinc PCA and sarcosine help support balanced oil production. This helps reduce the look of excess shine without making the skin feel dry.
Barrier and tone support
Niacinamide supports the skin barrier and helps improve the look of hyperpigmentation-related unevenness. Skin looks calmer, clearer and more even over time.
Key Ingredients
10% Niacinamide
A multi-functional form of vitamin B3 that supports the look of pores, blemish-prone skin, uneven tone and barrier function. It helps skin look smoother, calmer and more balanced.
Zinc PCA
A zinc-based ingredient that supports oil balance and blemish-prone skin. It helps skin look less shiny while keeping the formula non-drying.
Sarcosine
An amino-acid derived ingredient used for oil and pore appearance support. It helps skin look more balanced and pores appear more normalised.
Glycereth-26
A hydrating humectant that helps the serum feel comfortable on the skin. It supports lightweight hydration without adding richness.
How to use
Apply a few drops after cleansing, morning and/or evening, before moisturiser. Use alone or mix into a simple hydrating serum, such as hyaluronic acid. Do not mix directly with exfoliating acids, direct acids or pure vitamin C.
With vitamin C:
Use vitamin C in the morning and B-Bomb in the evening.
With exfoliating acids:
Use exfoliating acids on alternate evenings, or use B-Bomb in the morning and acids at night.
With retinoids:
B-Bomb can usually fit into the opposite routine or be layered carefully, but for sensitive skin, keep it simple: B-Bomb in the morning, retinoid at night.
FAQ
What does B-Bomb do?
B-Bomb is a 10% niacinamide serum designed to support skin that looks oily, congested, uneven or prone to visible blemishes. Niacinamide helps improve the look of enlarged pores and uneven tone, while Zinc PCA and sarcosine support oil balance so the skin looks less shiny. The formula also adds lightweight hydration, so it supports a smoother, calmer-looking complexion without drying the skin out.
How does niacinamide work in the skin?
Niacinamide is a form of vitamin B3 that helps support several visible skin functions at once. In the skin barrier, it supports the production of important barrier lipids, which helps the skin hold onto moisture and feel more comfortable. For uneven tone, niacinamide helps reduce the visible transfer of excess pigment to the skin’s surface, which can soften the look of post-blemish marks and hyperpigmentation over time. For oily or blemish-prone skin, it helps balance visible oiliness, while Zinc PCA and sarcosine add extra sebum-supporting benefits. This is why B-Bomb can help skin look smoother, calmer, less shiny and more even without exfoliating or peeling the skin.
Who is B-Bomb best for?
B-Bomb is suitable for all skin types, especially combination, oily, acne-prone and blemish-prone skin. It is a good option if you want a lightweight serum for pores, shine, blemishes or uneven tone.
Can I use B-Bomb every day?
It can be used morning and/or evening. If your skin is easily reactive, start slowly and increase use as your skin tolerates it.
Can I use B-Bomb with vitamin C, exfoliating acids or retinoids?
B-Bomb layers well in many routines, but do not mix it directly with exfoliating acids, direct acids or pure vitamin C. To keep the routine simple, use B-Bomb in a separate routine from strong actives — for example B-Bomb in the morning and retinoids or exfoliating acids in the evening.
Is B-Bomb suitable for sensitive skin?
The formula is fragrance-free, essential oil-free and hydrating, but 10% niacinamide can feel active for some easily reactive skin. Start with a small amount or lower frequency if your skin is sensitive.
Is B-Bomb pregnancy-safe?
Yes, B-Bomb is pregnancy-safe. If you are breastfeeding or unsure, check with your healthcare provider before use.
