Numbuzin No.3 Bifida Bakuchiol Zero Pore Serum Review – Unlocking Glassy Skin

Numbuzin has launched into the 2026 season with a vibrant new addition to their famous no.3 skincare line. Their No.3 skincare line has always been about improving skin ‘texture’ and improving large pores, fine lines and creating a glassy, nourished finish. They were challenged to take pore care to the next level and have switched it up with a vibrant blend of bifida ferment (for rich probiotics) blended with galactomyces ferment (for brightening) and bakuchiol for a boost in natural elasticity. 

This strengthening trio has been carefully formulated to deliver rich hydration and pore care without the risk of irritation and was so adaptable they’ve completed a whole skincare routine with it. Not only is the main trio of active ingredients gentle, balanced with silk, goat’s milk extract and gentle panthenol, it’s carefully designed to be compatible with sensitive skin types. 

Bifida ferment lysate is an old-school and beloved Korean beauty ingredient that is essentially a probiotic that is carefully cultured to cultivate skin-healing ingredients and molecules, before being spun down and purified. It is an ideal ingredient for damaged or inflamed skin as it has natural barrier repair, improves hydration, reduces redness, irritation & improves your skin natural defense. 

Galactomyces Ferment Filtrate (GFF) is naturally produced as a fermented byproduct of sake, that was first noticed when experienced sake makers had youthful hands despite their age, due to being submerged in the mixture. Rich in antioxidants, its a powerful skin-protective ingredient that helps seal the moisture and form protection against environmental pollutants. It is a combined skin treatment that helps reduce large pores and balance oils, whilst improving natural elasticity and brightening skin texture. 

So, is this trio of bifida extract, galactomyces and bakuchiol enough for deep pore care, compatible for sensitive skin and (most importantly) does it give results? Let's put it to the test!

Bifida Ferment: forming the base of this soothing serum, it is rich in calming, hydrating molecules that help boost the skin biome for refreshed, clearer skin texture. 

Galactomyces Ferment: by-product of sake production that is rich in natural antioxidants and probiotics that helps soothe the skin, improve skin barrier function and deepens hydration, whilst balancing oils to reduce large pores. 

Niacinamide: brightening vitamin B3 that helps reduce dark spots and smooth uneven textures, whilst leaving skin with a radiant glow.   

Alteromonas ferment: deep marine extract that helps boost natural collagen synthesis and protects skin deeply against environmental pollutants and stressors to prevent daily damage. 

Silk extract: rich moisturizing extract that helps stimulate skin cell healing and boosting collagen for plump, dewy skin. 

Goat’s Milk extract: nourishing, fatty extract that helps stimulate deeper layers of moisture, clearing dead skin cells and helping balance the natural pH. 

Lactobacillus ferment: deeply soothing probiotic extract that helps stimulate skin repair, resets immune function to reduce redness and inflammation, whilst providing naturally healing peptides. 

Bakuchiol: plant-based retinol derivative that helps stimulate skin elasticity, regenerating underlying structures for skin firming and improving fine lines and pores. 

Panthenol: hydrating and soothing vitamin B5 that helps improve skin strength and re-balance and protect sensitive skin.   

Adenosine: revitalizing molecule that helps stimulate cell energy and boost collagen production for smoother and more youthful skin.   

Kojic Acid: vibrant, brightening extract that helps treat dark spots and improve skin glow, evening skin texture and appearance. 

Allantoin: moisturizing cell agent that helps exfoliate away oils and dead skin cells, whilst boosting skin repair underneath.   

This gentle, hydrating serum is designed for sensitive skin, oily skin and gentle moisture. It's genuinely compatible with a wide variety of skin types and the only contraindication is if you are allergic or sensitive to one of the ingredients.

It's a skincare line designed for texture improvement; making it great for fine lines, large pores, pigmentation and dry spots.

I have skin with fine lines and pores and always love a well-designed serum. I was hoping that this serum would improve pore appearance (as per the advertising) and added it to my daily routine (AM) to see if it could bring out true results.

The serum itself is gently hydrating and incredibly lightweight. It has that classic bifida base, which is a misty, refreshing texture that helps cool the skin as you use it. Without harsh active ingredients, this serum is also incredibly compatible with a range of skincare ingredients & routines.

After two weeks of use, you can see the gentle glow to my skin. It helped improve pore texture and helped plump the skin around my eyes for a firmer texture.

As with any gentle formula, you will not get dramatic results on the fly. But if you are after an incredibly skin-compatible, gentle and nourishing formula; this serum is very well formulated. 

It's a holistic serum that will fit into a variety of routines to help improve skin texture, tone and reduce uneven spots & patches.

This lightweight, velvety serum is a great addition to any routine looking to improve skin texture (from dark spots, to scars, to fine lines and dry patches). It's soothing, cooling and well suited to sensitive, oily and dry skin types.
