Wow, my skin looks SO much brighter

I honestly wasn't expecting this much of a difference. My skin was looking really dull and uneven and after about a month it looks completely refreshed. I've actually stopped wearing foundation most days because I like how my skin looks without it. My old acne marks are fading too. Absolutely keeping this in my routine.

Acne marks are fading

This is what sold me on it. I had three dark marks left from spots on my cheek that seemed to have been there forever. They're still visible but much lighter now, after about six weeks. I use it every night, and SPF religiously in the daytime.

Nice for sensitive skin

My skin reacts to basically everything, so I was expecting some stinging or redness. Nothing. I've been using it every second night for about five weeks and my skin looks much calmer and more even. So far I'm impressed.

Finally something for my dull skin

My skin always looks tired no matter how much I sleep, and this has actually helped. Not overnight. It probably took two or three weeks before I noticed anything. Now my face just looks fresher and a bit more even. I've started using it on my neck too.

That glow

I bought this mostly for old acne marks, but the first thing I noticed was the glow. my skin just looks healthier even without make-up. Some of the marks on my cheeks are starting to look lighter too, but I've only been using it about five weeks.

I didn't realise how dull my skin was

I honestly thought my skin was fine before. Then after using this for a month I looked at some older photos and realised how much more even my complexion looks now. It isn't a massive dramatic change, just less grey and tired looking, if that makes sense.

My skin looks brighter

I've been using this around a month and my face definitely doesn't look as dull as it did before. I wouldn't say my dark spots are gone, but everything looks more even somehow. Really nice serum.

My freckles haven't disappeared, and that's fine

I wasn't looking to erase my freckles or completely change my skin colour. I just wanted the patchiness and old acne pigmentation to look less obvious. After roughly seven weeks that's exactly what I'm seeing. My complexion looks more even but still like my skin. Very happy with that.

Obsessed with this serum

Finally!!
I've tried SO many products for pigmentation and most did basically nothing. This is the first one where I can genuinely see my darker marks getting lighter. I'm about 7 weeks in and the difference in my overall complexion is amazing. Brighter, smoother, more even... just really good skin days lately.

Really surprised by this

I bought it because I had a patch of pigmentation on one side of my face that was driving me mad. I'm not going to say it disappeared, because it didn't, but after around two months it is definitely less noticeable. What I wasn't expecting is how good the rest of my skin looks. Much brighter and smoother. I've actually been wearing less foundation lately.

It makes my skin look alive again

I'm 50, and pigmentation isn't even my biggest issue. It's that my skin has started looking dull and tired all the time. This has really helped with that. There's more glow to my face now and my skin tone looks cleaner and more even. Hard to explain, but I look less exhausted.
