Use it every morning make this serum more effective and improve brighter.

This product was very allergic for me, cannot use :(

IT HAS A LIGHT TEXTURE. I AM SO HAPPY WITH THIS PRODUCT

I didn't use it I order it for a friend.

The texture is quite thick and there is a head sensation on the skin so I use this serum at night

يغذي البشرة وترطيبه حلو و يخفف التصبغات 

Bought this serum for a friend and she loves it, has really good brightening effects.

I bought this product for my mom.. she loved it.. it's like her daily skin care routine.. highly recommended .. it's concentrated vitamin C

product it is good on the skin and a good moisturizer.

good stuff to purchase again

best product I will purchase this again

On my second bottle--can't beat the price for a real ascorbic acid vitamin c product, with a higher percentage at that. I don't mess with high fuss vitamin c--I kept this at room temp, and it's stayed clear. When I have hormonal breakouts now, any hyperpigmentation left after is minimal, at best, and this fades it quickly. I use it AM & PM for best results--and I only need to use 3-5 drops so it also lasts longer before a repurchase.

Started using the morning glow is amazing. The consistency is a bit a let down heavy and sticky good for night use.

It brighten my skin and minimized my pores. I used it every morning

This is a high concentration of the good stuff--22% ascorbic acid, 2% derivative. Not for beginners. If you need the pure VitC, and can handle a higher concentration, here you go. If you aren't trying to shell out for expensive American Brand (iykyk), & you don't have time for fussy products, this is for you. I'm almost through the bottle, I store it at room temp, and it's still clear--see my photos for the dropper and some on my hand. It handles my PIH from my breakouts like a boss.

Water-free so can feel oily on the skin. Not thin oily, medium viscosity serum. Recommend putting on a soothing toner then apply serum when skin is damped. Combining with Tiam 10 Niacinamide helps fade pigmentation on No. 21-23 skin tone in 2 weeks.

I really really really love these product so so much!!! Absolutely amazing! Obsessed!

لا بأس فيه ترطيبه حلو يقولون انه يفتح البشرة لكن اتوقع بياخذ فترة من التجربة

Excelente formulación Al principio es oleoso al pasar los segundos esta sensación desaparece Me gusta que no se oxide tan rápido Muy tolerable para piel sensible a pesar de su concentración

Very potent serum for hyperpigmentation

It is gentle serum but the texture is quite greasy at first, but it is the common texture of vitamin c serum

so far so good, no major sensitivity problems I get from other Vita C products.

I like this vitamin c, you can feel it right away that is pure vitamin c and the concetration is superb.

Es una vitamina C al 24% adicionada con Glutatione que es un poderoso antioxidante lo que potencia el beneficio para las manchas y para que dure más el producto

This is one of the best products from StyleKorean. While consistency is key, this Vitamin C bottle will make your face look healthy, brightened, and it does not irritate or have any side effects. I have eczema and a dry/combination skin and this product has been great so far.

I had a blister on the side of my nose that had already healed a few weeks prior to use and it disappeared after using it. I was worried of scarring or discoloration, but I think this product helped even out my blister wound. I would use this twice a day, before applying a Neutrogena rapid wrinkle repair retinol (every other night) and/or Skin1004 Mad. Cent. Soothing Cream.

The 22% vit C and 2% derivative will make your skin bright with even skin texture and you, more comfortable with yourself! The powers of Vitamin C are marvelous and after patience and time you will dive into a blissful world of youthful radiance and flawless glow! It wasn't a surprise for me as I have been using serums with high percentage of actives, so I use this one at night as it have oily finish. No irritations at all!!

I recently tried Tiam Vitamin C24 Surprise Serum, and it has truly transformed my skincare routine. The lightweight formula absorbs quickly without any greasy residue, leaving my skin feeling refreshed. The powerful blend of Vitamin C, hyaluronic acid, and antioxidants worked wonders in reducing fine lines and evening out my complexion. After just a few weeks of use, I noticed a remarkable improvement in the radiance and texture of my skin. The serum's gentle formulation didn't cause any irritation, making it suitable for my sensitive skin. The convenient dropper bottle ensures easy application, and the sleek packaging adds a touch of elegance to my skincare regimen. Overall, Tiam Vitamin C24 Surprise Serum has become a must-have for achieving a brighter and healthier complexion, and I highly recommend it to anyone looking to elevate their skincare game.

This serum has a liquid texture with a clear liquid. There is no orange aroma that is typical of vitamin C. Selin is also comfortable when worn and is indeed good for antioxidants
