I have finished a bottle last time and this I remember this serum is pretty good, it doesn't breaks me out and have seen effect in fading my scar/post acne pigmentation gradually.

It works well on combination/dehydrated/bumpy skin like mine. It leave my skin feeling kind of matte (not dry) not sticky after applied. I will usually top up with another hydrating product to use together.

The only complaint is it's smell of citrus is quite strong and if I have some open wounds (due to acne) and it will stings.

I have losts of red blemish and dark spot from acne scar and this definitely cures it.
EFFECTIVENESS: Not as effective as other ascorbic-acid serum (like The Ordinary) but has noticeable imrpovement. Lighten skin and darkspot. Calm my reddish acne blemish. Suitable for all skin type especially oily skin
TEXTURE: Very,very light,fast absorb,so u need to quickly spread before it absorbs.
SMELL: Very citrus-y,like mandarin orange u eat during Chinese New Year lol
HOW LONG A BOTTLE LAST?: Its only 60ml,so it last about 3 months. If u want it to last longer, use it only at problematic area. for example, most of my blemish is at jawline (hormonal acne) so i only use it there. And I manage to make it last longer for about 4 1/2 months.

i have a really oily skin and acne prone skin, i breakout so many times. there a lot of blemish in my skin. so i decide to try out this product, end up I LOVE IT SO MUCH. with all the ingredients, how can you not love it? i love the texture, its super lightweight and the smells is so nice. ADSORB TO MY SKIN REALLY FAST, FADE MY BLEMISH, AND CONTROL SEBUM PRODUCTION. maybe its not that effective as ascorbic acid, but still its work without irritation your skin. for those who searching for a good serum that can help reduce your blemish but not sting your skin, YOU GUYS SHOULD BUY THIS.

Yuja niacin serum has an amazing smell that I favour a lot. It smells like a mandarin orange. Once I apply it on my skin, I could feel that the serum absorbs faster and would make me feel like I haven't apply it yet. As I have combination skin, it doesn't feel sticky but it's not really hydrating so I guess I would not recommend it to dry skin type.

Basically my face is dry to normal skin type, and super sensitive one that i have to properly choose and doing lot of reviews reading and googling every single time before buying a new product. So from my reading, i found this Some By Mi Yuja Niacing Series - Serum and its Sleeping Mask.

As for the serum, it was so light and easily absorb onto my face, doesnt leave any stickiness and does wonders on my redness and some small pimples. In my pimple case, i once wore a sheet mask and some pimples pop up on the next morning, so i just dotted the serum and by evening, the pimple was dried out and vanished.

Face also feels tightened than before so yeah, sensitive fellas, no worries if you wanna try this out. But, in case youre still worrying, when you bought this serum (any products you wanna try for the first time), please please please for the first day, only use just a few dots or small amount of it, then add the amount on second day, at least take 3 to 4 days to really wear it full face thus your face can adapt with the product. Best of luck in taking care our precious face!
