Concentrated Vitamin C Serum Derma E Vitamin C Serum (miniprodukt)

This serum is excellent and effective. It evens out skin tone and adds a healthy glow. It even helped clear up some of my breakouts. I'll definitely be purchasing a larger bottle.

The serum is decent and offers some brightening effects, but it doesn't help with breakouts. I tried the 15ml size. My favorite is still the Acne Blemish Control Treatment Serum—it soothes, heals, and dries out blemishes, leaving my skin almost perfect by morning! It's a shame it's not available.

I purchased this serum to even out my skin tone and achieve an antioxidant effect. I'm very pleased with the results. After using the serum once a day regularly, my skin looks noticeably better, and the number of breakouts has even decreased. It didn't cause any negative reactions.

The serum is quite good. It has a light consistency similar to a liquid fluid. I personally don't experience any stickiness from it. I apply it in the evening under my moisturizer, and in the morning, I skip the moisturizer. It doesn't pill, and makeup products apply beautifully over it. As for the effect, there's nothing extraordinary, but it does provide moisture and care.

I have a full-size bottle of the serum, containing 60 ml, which I purchased elsewhere. The serum has a cloudy white-yellowish color and is quite nourishing. During the summer, it feels too heavy for my skin, so it would be more suitable for fall and winter. Currently, I don't apply a cream over it; I just follow up with SPF, and it already feels like too much. Despite this, I like the effect it has on my skin—my complexion has become more even, and I've had no breakouts at all.

I really liked the serum. My skin has become brighter, and it has a pleasant scent. I've been using it for 10 days. I'm over 50.

I really liked the serum. I use it exclusively at night and follow up with a night cream. My skin feels smooth.

This is a pretty average serum. I didn't notice any significant effects—neither good nor bad. I'd rate it a 4 out of 5.

I liked the serum. If you apply just a little, it doesn't leave a film, and it makes your skin feel nice.

I purchased all the products in mini sizes. I didn't like the Vitamin C serum. It leaves a noticeable film on the skin, which starts to roll off after a few hours. I also didn't see any visible improvements in my skin. The toner from this line was also disappointing; it leaves a similar film and doesn't cleanse the skin. However, the night and day creams are effective and show visible anti-aging benefits. Unfortunately, the scent is unpleasant, like an old expired cream. If it weren't for the labeling on the packaging, I would be hesitant to use it.
