This is the best form of vitamin C! My combination skin is prone to pigmentation and post-acne marks. After using this serum at night, I noticed my skin looked lighter and fresher in the morning. For the price and volume, it's exceptional! I've even ordered more for friends and recommend it highly.

Improved closed acne
71 people found this helpful
It took some time before I began to see results. The closed acne on my chin had lingered for quite a while. After researching online about retinol, I purchased a retinol essence alongside vitamin C and hyaluronic acid. I apply retinol, hyaluronic acid, and a moisturising cream at night, while using vitamin C and sunscreen during the day. Now, my closed acne has significantly improved, and my skin feels firmer and smoother! I hope this experience proves helpful to you.

Reduces redness
10 people found this helpful
This serum has been a revelation for me. My skin is prone to rashes, but this serum effectively heals and reduces redness associated with acne. After just a week of use, the spots from long-healed pimples have faded considerably. It’s now my favourite product and I intend to continue using it, as I've heard it can also help with wrinkles! The texture is pleasant and I only use it at night, followed by my cream. Overall, I’m delighted!

Reduced acne visibility
7 people found this helpful
This vitamin C might be the best I've purchased! After about ten days of use, my skin looks less dull and more transparent. A colleague even noticed my bright skin! I observed a reduction in acne around my chin and fine bumps on my forehead. It feels smoother, and while the texture is thick, it blends well and leaves a pleasant citrus scent. I’d recommend getting it while available!

This serum effectively reduces acne marks and brightens my skin. When I apply excess on my cheeks and nose, it noticeably diminishes whiteheads. With regular use over a month, my acne marks and pigmentation have significantly lightened.

Scar disappearance
11 people found this helpful
To be honest, I used this for my acne scars, and within two weeks, they had vanished due to the Vitamin C serum. It’s essential to refrigerate it to prevent the smell from oxidising. I apply it every morning on dry skin. The quality is superb; with a large size, it lasts between 3 to 5 months. The formula is gentle and does not provoke sensitivity or recurrence, which is a significant benefit.

Glowing skin
5 people found this helpful
This is a fantastic product! I ordered it for the first time; the large darkened bottle is well-packaged. I'm 39 and have pigmentation, acne, and wrinkles due to oily skin. I use it each morning after my tonic by applying directly onto my skin, and after a few days, my skin has visibly glowed! Even my husband noticed. The pleasant scent is addictive, and its delicate composition suits my sensitive skin perfectly. After using it consistently, I noticed my acne started to clear up within a week. This product truly is a gem!

Scar reduction

I absolutely love this vitamin C; it truly works! I’ve been using it consistently for a couple of months and am thrilled with the results. My acne scars have vanished, my skin has brightened, and it has helped dry up my acne. My fine lines on my forehead are also fading, which amazes me. With no adverse reactions on my combination skin, I pair it with a niacinamide serum for enhanced results. Three drops cover my entire face, and the bottle lasts over three months.

Less acne appearance

This will be a repeat purchase. Using 5% niacinamide from the same brand has resulted in fewer acne occurrences and quicker healing when they do appear. I'm pleased with my skin's improvement, and my dark spots are fading. Just be careful with any facial scratches, as they may stain temporarily. I find the serum very effective!

Lightens marks

Great value for money! This product effectively fades my acne marks. I initially tried it following recommendations, and after seeing results, I now recommend it to others. The vitamin C absorbs quickly, without feeling heavy on the skin, and astonishingly, it truly lightens my acne marks. I can see a slight difference in my complexion as well. Definitely planning to repurchase for a long time!
