I really love this serum, it is very effective for my combination and sensitive skin, my skin with it looks more even in color, less age spots and a more elastic texture. I use 2 drops on dry clean skin, after it absorbed cover it with moisturiser, but don’t mix it with Acids or Vit C , but it’s compatible with Niacinamide I definitely recommend

value for money.....with a big bottle, I bought when discounted. I am always satisfied with this Korean manufacturer. I have used this product before and had a hard time finding it in my country. but I'm happy to find it here. So far I've used several retinol serums, but I like this serum the most, it doesn't dry out my skin and My skin tone is getting better

I've been using it for a couple of weeks, so far I can say good things about it. Easy to absorb, no greasy feeling, pleasant to the skin. it doesn’t irritate my skin even though i use it every night in my routine. I notice that it smoothes the skin. It doesn't smell. Its packaging is also very hearty. So far proven, I'm glad I was able to buy it in action.

I love everything retinol. This makes my skin instantly tight and smooth. The result lasts for hours and is visible. I wish they made a product with more than 2.5% retinol! For some reason, all serums are topped at this number. I would buy a product with more than 2.5% retinol for sure.

My mature, resistant pigmented combo skin did't experience any bad reactions, in fact I noticed my pores reduced, my melasma is clearing up a little bit and skin feels more supple. I've been using 1 drop for my entire after tonic every night before bed. No night cream needed. Wash my face in the morning and apply sunscreen after moisturizing. It's oily-like texture when it comes out of the bottle, but skin absorbs it well after applying. No scent. Exccellent size for the price!

I got this because I was having trouble finding a retinol night cream with a nice essential oil fragrance. Most are fragrance free or perfumed. So I use this in conjunction with a non-retinol night cream, and I have noticed a smoothing of fine lines. The scent is pleasant and lavendery, but very mild. The dropper is not the greatest.

I've been using this product for about more than a month now and I have yet to see some great results like softening of thin wrinkle lines. However, I do have very sensitive skin and some of the strong retin-a have caused reactions and I was so happy this didn't cause any reaction or irritation to my skin given that it's quite strong (2.5). I will wait and see if over time it will show better results before I order another bottle.

This is my second purchase of this product. I liked the texture (oil that may be used on top of the toner), I use it each night. I did not feel any discomfort or dryness if my skin, however my skin is usually fine with retinol products and they don't cause any irritations. I liked the effect after using my first serum, so ordered again

r I really like this product but I can't use it in summer because my skin is gentle and sensitive. I use once a week only before bed

It's quiet strong serum, my skin got used to it after a few weeks, was sensitive from the beginning. However I feel it's working, I use 3 times a week at night. DO NOT use in the morning routine.
