Key Ingredients and Formula
The formula behind this serum is what makes it stand out. Bifida Ferment Lysate makes up 42% of the serum and serves as the star ingredient. This fermented ingredient helps break down dead skin cells and improves how your skin feels to the touch.
Galactomyces Ferment Filtrate comprises 21% of the formula. This yeast derived component works to brighten your complexion and boost hydration from within. Together, these two fermented actives create a powerful duo that addresses texture issues at the source.
Beyond the fermented ingredients, the serum includes several supporting players. Niacinamide strengthens your skin barrier and reduces excess oil production. This vitamin B3 derivative also calms irritation, making the formula suitable for sensitive skin types.
Adenosine enters the picture to improve elasticity and firmness. This nucleoside works by promoting collagen production, which leads to smoother, more youthful looking skin over time. You’ll notice your skin feels more supple with regular use.
Butylene Glycol acts as a humectant in this formula. It draws moisture into your skin without leaving a sticky or heavy residue. Your skin stays hydrated throughout the day without that uncomfortable tacky feeling.
The ingredient list keeps things straightforward and focused. There are no unnecessary fillers or fragrance additives that could irritate sensitive skin. This simple approach means fewer potential triggers for reactive skin conditions.
What makes this formula smart is the concentration levels. The high percentage of fermented ingredients means you get maximum benefits without diluting the actives. The supporting ingredients work in harmony rather than competing for your skin’s attention.
The 50ml bottle size makes this serum easy to incorporate into your routine. A little goes a long way, so one bottle lasts several months with consistent daily use. The lightweight texture absorbs quickly, leaving no white cast or greasy shine behind.
This combination of fermented power and supporting actives creates a formula that genuinely improves skin texture. Users report softer, clearer skin within weeks of starting this serum.

Texture and Application
When you apply this serum, you immediately notice its lightweight consistency. The texture feels silky and smooth against your skin without any sticky residue. It glides on effortlessly and absorbs quickly into the skin.
The serum has a thin, watery consistency that resembles a hydrating toner more than a thick serum. This means it works well under other products in your routine. You won’t experience any pilling or layering issues when you combine it with moisturizers or sunscreen.
Application is straightforward and simple. Dispense a few drops onto your fingertips or palm. Gently press the serum into your face and neck using upward motions. Most users complete this step in under one minute.
The non-greasy formula makes it ideal for morning and evening use. Your skin feels hydrated but never weighed down. People with oily or combination skin appreciate that it doesn’t create a slick feeling on the face.
During the first week of use, you might notice your skin feels softer immediately after application. The hydration boost from Butylene Glycol kicks in right away. However, visible texture improvements and pore refinement take consistent daily use for two to three weeks.
The serum spreads evenly across the face without requiring much effort. A little goes a long way, so you don’t need to use large amounts per application. The 50ml bottle lasts quite a while with regular use.
Some users mention a very faint scent that disappears quickly. The formula itself is fragrance free, so any smell comes from the fermented ingredients. This doesn’t bother most people, but sensitive noses might notice it initially.
The gentle absorption means you can follow up with your next product almost immediately. No waiting time is necessary between steps. This makes the serum convenient for busy mornings when you’re rushing through your routine.
Skin Types and Suitability
Numbuzin No.3 works well for several skin types, though it shines most for people with specific concerns. Oily and combination skin find this serum particularly helpful because the fermented actives gently refine pores without adding weight or grease.
Normal skin types benefit from the hydration boost. The serum delivers moisture without overwhelming your skin barrier. You get softness and smoothness without any sticky residue.
Dry skin can use this serum successfully, but layering matters here. Apply it to damp skin, then follow with a richer moisturizer to lock in the hydration. The fermented ingredients support skin barrier health, which helps reduce dryness over time.
Sensitive skin needs caution with this one. The fermented lysates are generally gentle, but always patch test first. If your skin reacts to fermented products, this may not be your best choice. Start with a small amount twice weekly before increasing frequency.
Acne prone skin often sees improvements because the serum addresses texture and pore congestion. Many users report fewer blackheads and smoother skin after consistent use. The niacinamide content also supports skin that struggles with breakouts.
Mature skin appreciates the adenosine content. This ingredient supports elasticity and firmness, making the serum useful for people targeting fine lines alongside texture concerns. The hydrating formula helps plump skin and reduce the appearance of wrinkles.
People with rough, bumpy texture should absolutely try this serum. The bifida ferment lysate concentration of 42% targets this issue directly. You’ll notice your skin feels noticeably softer within days of starting.
Avoid this serum if you have active severe acne or open wounds. The fermented ingredients may irritate inflamed skin. Also skip it if you’re allergic to any fermentation byproducts or yeast.
The key across all skin types is consistency. Apply morning and evening for best results. Most people see meaningful improvements within two to three weeks of daily use. Your specific skin type determines how quickly you’ll notice changes, but the serum adapts well to different needs.

Results and Effectiveness
This serum delivers visible improvements in skin texture within the first two weeks of consistent use. Most users report noticeably softer skin after just a few applications, with the effect becoming more pronounced over time.
The fermentation complex works by gently exfoliating dead skin cells while simultaneously hydrating deeper layers. This dual action explains why people see such dramatic texture refinement. Your skin feels smoother to the touch, and rough patches gradually diminish.
Blackheads and enlarged pores show significant improvement with regular application. The Bifida Ferment Lysate penetrates pores and removes trapped debris without harsh scrubbing. Users with congested skin often notice their pores appear smaller and less noticeable after four to six weeks.
The hydration results are immediate but build over time. Your skin feels plumped and refreshed right after application. After two weeks, this hydration becomes more lasting because the serum strengthens your skin barrier. You’ll notice your skin looks dewier and feels more resilient.
Firmness and elasticity gradually improve thanks to the adenosine content. This isn’t an overnight transformation, but consistent users see subtle lifting and a more youthful appearance after six to eight weeks. Fine lines appear less pronounced when skin is properly hydrated and firm.
The serum works exceptionally well for people with bumpy texture or uneven skin tone. These concerns often fade within three to four weeks. Your complexion looks more polished and refined overall.
Results depend heavily on consistency. Using it once or twice won’t create lasting change. Daily application morning and night delivers the best outcomes. You must also maintain a complete routine with moisturizer and sunscreen to maximize benefits.
Most users reach peak satisfaction around the eight week mark. By this point, texture improvements become undeniable, hydration feels natural to your skin, and pore appearance has noticeably improved. The serum essentially trains your skin to maintain better health on its own.
The 4.9 star rating reflects these real, measurable results across hundreds of users with different skin types and concerns.
How to Use for Best Results
Start with clean, dry skin. Pat your face gently with a towel until it feels slightly damp, not soaking wet. This step helps the serum absorb better into your skin layers.
Dispense 2 to 3 drops onto your fingertips or directly onto your palm. The serum’s thin texture means a little goes a long way. You don’t need much product to cover your entire face and neck.
Gently press the serum into your skin using your fingertips. Use upward motions on your face and downward strokes on your neck. Avoid rubbing or tugging, as this can irritate delicate areas. The key is to let the serum sink in rather than spread it aggressively.
Wait about 30 seconds to one minute before applying your next product. The watery consistency means it absorbs quickly, so you won’t experience a long wait time. This brief pause allows the Bifida Ferment Lysate and Galactomyces Ferment Filtrate to begin working on your skin.
For morning routines, follow with a lightweight moisturizer and SPF. The serum pairs well with hydrating creams and doesn’t interfere with sunscreen application. At night, you can layer it under your regular night cream or sleeping mask for enhanced hydration.
Use this serum twice daily for best results. Morning and evening application ensures your skin gets consistent exposure to the fermentation complex. Consistency matters most when targeting texture issues and pore congestion.
If you have dry skin, consider layering two applications of the serum before moisturizing. This technique, called “layering,” boosts hydration without feeling heavy. Apply the first layer, wait 30 seconds, then apply the second layer.
Don’t mix this serum with vitamin C or strong actives like retinol on the same night. The gentle formula works independently and doesn’t need boosting. Mixing products can reduce effectiveness or cause irritation.
Track your progress over eight weeks. Most users notice softer skin within two weeks, but peak results appear around the eight week mark. Taking photos helps you spot improvements in texture and pore appearance that daily observation might miss.

You should buy this serum if you struggle with blackheads or enlarged pores. Many users see visible reduction in pore appearance within the first two weeks. The results keep improving as you stay consistent with your routine.

This serum suits anyone looking for a hydrating alternative to stronger exfoliants. You don’t need a prescription or professional treatment to use it. Simply add it to your morning and evening routine for best outcomes.
Sensitive skin types should proceed with caution. While the formula is gentle, sensitive individuals may want to patch test first. Start with one application daily if your skin reacts easily to new products. You can increase to twice daily once your skin adjusts.
Skip this serum if you have active severe acne or open wounds on your skin. Wait until your skin heals before introducing it. The fermentation ingredients work best on healthy skin without compromised barriers.
People with dry skin can still use this product effectively. Layer two applications before moisturizing to boost hydration levels. The serum contains enough water content to support drier skin types.
Avoid mixing this with vitamin C or strong actives like retinol during nighttime use. Your skin needs time to adapt to new ingredients separately. Once you’re comfortable with the serum alone, you can experiment with layering strategies later.
Track your progress over eight weeks to see full benefits. Most users reach peak satisfaction around this timeframe. Consistency matters more than anything else with this product.
