For me this C-spurte is Ok, i didnt used it that much because i have something in my face that if i put these c-source it only itch...but i will continue to used this later when my skin is free from itchiness. And one thing this c-source applied to skin Its like your wearing mask on your face it dried up ur skin so better wash your face the day you wake up. Yes, i put this at night time. And that white stuff in cover area is just normal from it.

@tiam_global My Signature C Source - this fizzled up as soon I opened it (wasn’t shocked because I saw it happen to other people and the brand says it’s still safe to use) has 20% L-Ascorbic acid and 6000mg of 100% pure vitamin C for gentle peeling, exfoliation, and clearing out dark spots. Haven’t used this consistently so I can’t say how effective it is yet but will definitely give an update!

this actually really helped with my acne scars!

I bought this and I finished it but I dont remember it. I think the klairs vitamin c was better. I do appreciate they have amber glass packaging though.

I haven't tried it yet. hopefully it turns good for my oily and acne prone skin

I love this product. It has 20% of ascorbic acid which really work. I so the difference on the next day. It your skin is not super sensitive and you want to brighten your complexion this is the great choice for its price. Highly recommend it.

I'm veryyyyy recommeded this product. Love this product so much ❤❤❤

Little bit hurt on my face. I got acne when I use this. I have combination skin. Maybe this product not for me.

i liked this serum because i felt like it did brighten my skin and fade away from scars. i didn't use it consistently enough to know for sure though. i remember seeing a brightening effect the next morning when i first started to use this product. If you have really sensitive skin, it might burn (it burned a little for me, but only at first and went away so it was bearable). i stored mine in the refrigerator after opening. overall, affordable product and i liked it!

I think it helped with skin tone, but I feel like it does not.. Not really sure how I should feel about this product.

keeps the glow of my skin and radiance.

it's smell so good, but so sticky in first time I try. but this product makes my skin soft and bright. I love this :)

I have tried it for 1 month and I dont see any improvements. I'll keep trying it.

This one is highly recommended. I like this product, it reduces my dark spots and lighten my face. I will definitely buy this again

I guess it’s ok, I just don’t like that it make skin sticky for quite some time

Have been using this for awhile now. Can't remember how many bottles I've been through. Still works the best for me and will always repurchase :)

It is a bit stronger than Klairs Vit C, but it's still mild and effective! I love it!

I really love this product. I noticed that after 3weeks using it, my dark spot lessen and now it fades away. i surely buy this one more time. highly recommended

you cant beat the price on this one

 

it cleared my skin .. am happy with this one

try to use it quick and keep in in a dark place coz it will go bad quick 

 

its great and the price is a ++

use it quick or it will go bad on you and yes keep it in the fridge 

Yeyyy repurchase. I buy again for stock because i love this so much

Tiam signature C serum. Best vitamin C serum

It has an exfoliating effect which lightens my acne scars and brightens my complexion. Will definitely repurchase!

The expired of this serum is quite fast which is 1 year from production date

i love the smell. but in my case, it doesn't give meaningful changes :( it's second time I using this

This is my go to Vit. C serum. I tried to substitute it with the Purito Vit. C serum but it doesn't have the same brightening effect.  

First time using a Vit C serum... Apply a light layer of this otherwise feels sticky to touch Better for night use

First vitamin c I bought from Korea. It’s not easy to oxidise but the texture is sticky. Have to wait for a while for it to absorb into my skin. Not gonn repurchase

It’s good vit c product but effective wise it’s kind of okay

the claims are true that it really does a good job with brightening your skin. The only down side was that results dont appear fast. You really need atleast 2 weeks to notice great results.
