This serum has a lightweight, watery texture, and it absorbs almost immediately. My skin loves ferments, so I knew immediately this was going to be a new favorite! Leaves skin bright, hydrated, and improves overall elasticity.

This is great because it has such good ingredients! Everyone should try

I love it! Especially right now when Im breaking out and it just softens my skin and leaves it so soft and moisturized.

This is the first time me using this serum but I must admit it has worked like magic on my skin. I have smaller pores ,my skin texture looks better, acne is reduced,it has not irritated my skin but helped with hydrating it. I highly recommend this serum .

It make my face glow and healthy in the morning after use

It is a cloudy-lightweight serum that smoothens skin roughness and sagging pores. It has a mild scent and is easily absorbed. No sticky/greasy feeling when applied. Leaves the skin hydrated and moisturized.

This is a really moisturizing serum. It's a bit on the thicker side but it doesn't feel heavy. I only need a couple drops to sufficiently moisturize my skin. It has gentle effective ingredients in it that are great for all skin types. It deeply nourishes and rejuvenates my skin. My skin looks and feels much healthier now. I definitely recommend it.

Best serum I tried, leaves my skin soft

Light, fast absorbing consistency, layers well. Reminds me of typical hyaluronic serum. It is softening and moisturizing, but doesn't help much with skin texture. Contains a lot of good ingredients. I only don't like it does contain goat milk. It is good serum, but not special.

soy de piel mixta, pero mi piel lo lleva a los extremos o muy grasa o muy seca y eso me genera un problema al usar productos por que pude que me mejoren ciertas zonas pero otras todo lo contrario y este producto me dio mucho brillo y a la vez hidratación sin ser grasosa, me encanto el balance que conseguí, no es pesado y se absorbe super bien

It absorbs quickly, is not tacky. It doesn’t pill as well. Leaves the skin hydrated and moisturized. Helps oosts skin elasticity subtly. Reduces fine lines and smoothes roughness.

I feel something, but not yet give me the best

After making the switch to kbeauty, I realised the worth in gentle on the skin products versus the typical harsh formulas of western skincare. I like to use this in my regimen after (double cleansing, first treatment essence, hydrating toner) because it’s lightly exfoliating without over stripping my sensitive skin. I’ve noticed my skin brighter and clearer without any hints of dryness and any acne breakouts I have, heal faster and reduce overtime. Definitely worth repurchasing in the future for me.

Serum is concentrate and provide skin moist and healthy look. I used it and also recommend to my friend.

This made my skin so soft! I have combination sensitive skin and it did not irritate or caused any breakouts!

It's still a little to early to see any effects for texture improvement but I love how soft this serum makes my skin and how it has good ingredients. Can't wait to see how my skin improves with this.

Not bad so far. Too soon to tell but absorbs well and is hydrating. Leaves behind glowy finish.

One of the best. I recommend this it's will make your skin glowing

Been using this for months now and this is gonna be my second bottle and it’s super good timing coz i badly want to repurchase it and for $3.33 heck yes! Obviously i love it so much! I’m using Numbuzin products from serum, tone up sunscreen to masks and i love them all!

I have dark spot under eye zone and skin tone not smooth. After use this serum a while I feel dark spot look lighter and skin so moisture.

I was hoping to love this but I can’t see any Duffy in my skin and it doesn’t dry down completely and leaves me sticky

A must have in every house of fashionista's and those who simply love to take care of themselves! Can not say enough of a good stuff about this product. The serum is ideal for very sensitive skin as it works getly on it and has no smell. It is very ligh weighted and easu to apply, adsorbed in seconds and ideal for under makeup. Highly recommend this product

It's not heavy and doesn't make my skin sticky which is nice. I haven't noticed any difference yet though.

I love that this serum is 50ml which is more than some other serums that are only 30ml. Some of the key ingredient in this serum is the fermented galactomyces-bifida and is supposed to help smooth out rough dry skin and bumpy skin. While they compare this to the SKII Essence, I do think they are quite different and I see result only after regular long time use for brightening and smoother skin. There’s also niacinamide that helps with acne and skin texture, and squalene/glycerin that helps with moisturizing skin. This serum can be used day and night time and it took about a few months of continual use to see results. I love how this serum is not sticky after application and leaves skin glowing.

This serum left my skin glowing even just after a few uses! It is slightly moisturising without it being tacky or too drying, or not viscous enough. I chose this as one of my item for RSG because I heard really good reviews about it. Definitely a repurchase for me.

I love the number 3 Serum and masks as well! makes my skin feels like baby butt!

Numbuzin was not a name I'd heard that much about but now there is no stopping this brand. It does what it says on the tin. Does soften your skin along with leaving your skin feeling very refreshed. It applies well, absorbswell, and the softness really impressed me.

Enjoy using this product love it, definitely will repurchase
