numbuzin No.5 Vitamin Concentrated Serum, Glutathione & Vitamin Serum, Korean Skincare, Tranexamic Acid 4%, Niacinamide 5%, Glutathione + Vitamin C Complex for a Radiant-Looking Glow 1.01 fl oz

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.

I have sensitive, dry skin that is prone to hyperpigmentation from the sun. I've been using this serum for about two months now so I feel confident discussing what it can (and can't) do for my skin. The serum is very hydrating and gentle, and I was surprised to find it NEVER irritated my skin - even when my skin barrier was compromised and I was dealing with irritation from another product. That alone is enough for me to be impressed! It's also got a very rich, gorgeous texture. I'd say it's on the thicker side, and has a lot of glide to it as you apply it across your face. I find it to be hydrating and moisturizing, but because it's so rich it does take a second for it to sink in. I usually wait about 30 seconds before it dries down completely. Something I also appreciate is how dewy it makes my skin. Over the past two months I've noticed some modest but definite brightening from the serum. My dark spots have faded a bit and my skin is more plump and smooth. I notice less redness and irritation around my nose as well. But you shouldn't expect this to work miracles - this serum seems to work best as a gentle, progressive brightener rather than an intense active. It's perfect for someone like me who wants to benefits of a brighter skin tone without the irritation of harsher actives. This is very easy to integrate into almost any skincare routine, but here is a breakdown of who I think this serum is good for based on my own personal experience with it: This is for you if: -If you deal with hyperpigmentation from the sun or post-acne marks -If you want a brighter complexion but don't want to use harsh actives -If you use other more intense actives (AHAs, Retinol, etc.) and you want a little "boost" -If you have dry and dehydrated skin and need a serum that will help hydrate and moisturize This is NOT for you if: -You expect this to make a drastic difference in your dark spots -You have very oil or acne prone skin -You are looking for a vitamin C serum

Best oil so far! After consistent use, I’ve noticed a healthier glow and improved texture. I’ve been using the Numbuzin No.5 Serum and I’m really impressed with the results. It leaves my skin looking brighter, smoother, and more hydrated. The texture is lightweight and absorbs quickly. It’s a 10/10 It leaves beautiful glow on my face.

If you're looking for a brightening serum that delivers results without compromising skin barrier health, this is a good choice. It has a great blend for anyone dealing with hyperpigmentation, dullness or uneven skin tone. It’s gentle yet effective, absorbs quickly, layers well under moisturizer and sunscreen and leaves the skin feeling smooth and hydrated. There’s no irritation or purging and no strong scent. It is slightly pricey though but a little goes a long way. Just be consistent with use.

This product was originally recommended by my Korean mom and I've been using it for yearsss. It's lightweight and works really well for brightening and lightening up my dark spots. I highly recommend especially for the value.

Great product. I didn’t break out and it was easy to absorb

I ended up trying this because Cosrx was sold out of their 23% serum so I decided to try this one and I absolutely LOVE IT it works amazing and feels amazing and is packaged perfectly and gives me a nice and beautiful glow and very hydrating to the skin I love to use it in the morning and helps brighten and even my skin tone I pair it with my dark spot serum from Anua.

Ni vi grandes cambios en mi piel ,se que es bueno pero no ayuda mucho

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

It doesn't have any effect. It's just a waste of money. Also, the customer service is terrible. Although they promised a return, as advertised, the seller refused to process the return. Overall rating is 0, if that were an option. I do not recommend it. You can buy much better products from well-known brands for the same price.
