Repeat customer very happy with the product

Such a great product. My skin is spot less and even toned. Started working after 1 week of use. Would definitely recommend for hyper pigmentation and uneven skin tone.

Fair

Today is just my 4th night applying this serum on my face and I think its good.No rashes,no redness and I think it’s suitable to my skin the product is original

Second time buying this serum! Really helps even my skin out!!!

I have just used it for a week and find it quite sticky specially after applying the sunscreen or thé moisturizer, too soon to comment if it’s working , will continue till the product finishes

I like quick results

3-MONTH RESULTS (2x day): Slight fading of deep dark acne scars and age spots. Evens out skin tone. Gentle and not irritating. I am guessing this will take 6 to 9 months for deeper scars to fade. The pamphlet on Yesstyle.com shows 9.65% improvement in Blemishes after 4 weeks and 18.9% for even skin tone (this means expect slow steady results). They recommend also using the toner pad for faster results (165% improvement) but the combo irritated my skin. Overall, I like that it is gentle and will continue using it, right after the Toner. KEY INGREDIENTS: Contains the right chemicals known to fade dark spots like Glutathione, 4% Tranexamic Acid, 5% Niacinamide (both suppresses melanin), Alpha-Arbutin, Vit C, 3-0-Ethyl Ascorbic Acid, Tumeric etc. TEXTURE: Light serum, not sticky, absorbs quickly after Toner. Tap face gently for a few seconds after applying to help the skin absorb quicker before adding the next product (tip from korean skincare companies that works). ACNE PREVENTION TIPS: Best way to see improvement of skin is to keep the pores clear and acne from re-surfacing. I have not had a single breakout in 3 months using this routine. Also changed my skin type from Oily Combo to Normal. STEP 1 (2x day) - Use SEBUM CONTROL TONER to regulate skin oil production (I use NUMBUZIN No. 1 blue bottle) STEP 2 (2x day) - Use ANTIBACTERIAL SERUM to reduce inflammation (I use Beauty of Joseon Glow Serum w/60% propolis, Tea Tree) STEP 3 (2x week) - EXFOLIATE to keep pores clear, as clogged pores breed acne. I use Beauty of Joseon Ground Rice and Honey mud mask. Leave on face and neck for 15 minutes; this is a very gentle product. STEP 4 (Optional) - EAT food that aide the digestive system and help prevent acne like Yogurt, Kimchi and Sauerkraut (eat small amounts 2-3 times a week). I hope these tips are helpful to everyone.

He estado usando el Numbuzin Nº5 Serum y me ha gustado mucho. Tiene una textura ligera, se absorbe rápido y no deja sensación pegajosa. Con el uso constante he notado la piel más luminosa y uniforme. No me causó irritación y funciona bien dentro de mi rutina diaria. Buen producto.

i have used a number of vitamin c serums and i just havent been able to get on with any so far. L-ascorbic acid can be very aggravating to many people, causing sensitive skin that can flake and peel before getting used to the active ingredients. the way numbuzin has formulated this No.5 serum is incredible. It still has a slight hot dog water smell (if you know you know!) but its very mild, but it feels amazing on the skin. its left looking glowy but not artificially so, and i have seen a definite improvement to my skins texture and radiance. Best of all, there has been absolutely zero irritation. Amazing product and one that i will buy forever i expect!

I love it actually.i have been using this serum since last year i also recommend to my friends and my mother and she love it .she repurchased this like 7 times .its great for hyperpigmentation and skin discolouration and also dull skin .give it a try
