Retinol Serum High Strength for Face and Skin, Unique Double Active Ingredients of 5% Retinol & 2.5% Vitamin E, Outstanding Synthetic Effect to Reduce Wrinkle, and Dark Circle (1 PACK)

Very decent quality serum. I actually ended up using it on my fore arms cause of my KP because I got something different for my face, but I really like how it works. It's mild and doesn't cause any irritation, but I can still see visible results after a few weeks of use. Leaves skin feeling soft and almost kind of hydrated. My favorite part is that it's not at all sticky and doesn't leave any yucky residue afterwards. Definitely will consider buying it again in the future.

Seems to work well on the Milia around my eyes.

So before finally getting prescription tazarotene 0.1 retinol, I was using this twice a day never skipping a day. In my opinion there should have been at least some side effects during the initial "purging period" when I first started this product. With real retinol, almost everyone has a period of flaking, irritation, breakouts, etc. It's called the "purge". Sure enough with my prescription retinol my skin was very irritated (because it's very real and very strong). If this product was indeed "5%" which is very very strong, I would have most definitely had some irritation... I didn't at all. 😐 I would say it's probably equivalent to Carave over the counter products. It's hard to say.

I'm not too sure about this product. There are several reasons for this. The first is me, l'll be the first to admit it. I'm a natural born skeptic. When I read the ad for this product it seemed way too good to be true. An over the counter product that has 5% retinol instead of the normal limit of 2%. In the back of my head I thought well, it comes from overseas. Maybe this could be a loophole. Also Amazon had it as Amazon's Choice! The price was right so I bought it a bottle of 3erum 1ab's "Retinol Plus Serum" Double Active formula. I know it's only been a week, so I can't see any changes now, good or bad. I know it takes time. I can say I have been reading up on retinol products in general. What I found out is that retinol is a skin irritant & can cause redness, dry skin & peeling until the skin becomes used to it. I've been using this product - supposedly 5% retinol. There's been absolutely no problems at all. Don't get me wrong, I'm definitely not complaining, but was thinking that there would be some sort of skin issue since there's a higher percentage of retinol in it. Especially if retinol is listed as the second ingredient, right? In every U.S. product when you look at the ingredient label, retinol is usually somewhere between the 8th to 20th ingredient listed. I'm thinking if they didn't mess with the percentages, and it does actually have 5%, then maybe there is a strong possibility this product could be diluted with a lot of water (1st ingredient) and other ingredients. I will give the product a chance & finish this up bottle and reassess my findings. I will keep my fingers crossed & hope there will be an improvement in skin, and not turn out to be snake oil. ***UPDATE*** I first first wrote my review back in May. I meant to get back to update. I feel this product is a total scam. Maybe all these people raving about how good it is are experiencing a placebo effect, I don't know. All I know is that it didn't work for me. It seems that this product consists mostly of water, regardless of what the label on the packaging says. There has been no change in my skin from using this product. I gave it a fair chance, I used up the entire bottle with no change. I can tell you what has helped with fine lines and wrinkles. You have to start with a clean slate and clean your face, then moisturize, moisturize, moisturize. Another very important thing to do is to use sunscreen. Sunscreen is a very important skin regimen. UV rays can even pass through car windows as you're driving. That said, it's also important to find products that will not clog your pores. Some are definitely greasier than others. It's definitely a trial and error. Save your money and don't buy this product. Do your research and find a good moisturizer and a sunscreen that will work for you. Unfortunately there are no miracle products that are sold over the counter.

I only apply it lightly, with night moisturizer, once a week. Very strong stuff. Wait for it to fully dry before laying on a pillow. Sunscreen is an absolute must!

This product works so well I've ordered 3 more bottles. It has reversed wrinkles and pigmentation on my face. Just be sure to add sun block if you plan to go outside.

Inexpensive and works great!

Love this product for my face. Has helped wrinkles.

un peu inquiète au départ car j'ai choisi un sérum au rétinol. apparemment il faut être prudent quant à son utilisation. et bien, tout va bien. j'ai une peau mixte, 53 ans, une tache brune sur la tempe, sans rides prononcées. après 15 jours d'utilisation, sans aucune irritation, je remarque une belle amélioration de mes pores, un bel éclat et un petit éclaircissement de la couleur de la tache brune de la tempe. j'en applique également sur les taches de ma main gauche qui diminuent également. c'est pourquoi j'ai recommandé à nouveau deux sérums. je recommande donc. je précise avoir pris conseil par un autre évaluateur d'amazon qui expliquait que le matin il faut appliquer la vitamine C et le soir le rétinol sous forme de sérum, de contour des yeux et de crème de jour ou de nuit. bien entendu sans oublier le double démaquillage le soir et le nettoyage léger le matin.

Tengo 41 años y la piel seca y sensible con lo que pensaba que quizás me irritaria la piel pero no, yo lo utilizo para acabar con el acné (si habéis leído bien) que me sale en los primeros días de menstruación. Por la noche (por la mañana no es recomendable utilizar retinol) después de limpiar la cara con agua micelar me doy este suero dejo que la piel lo absorba y después me pongo mi crema nutritiva de noche. A la mañana siguiente se ve una clara mejoría de ese acné, a veces en solo dos noches de aplicarlo desaparecen. Como hidratante por sí solo no es suficiente para mi, siempre debo ponerme mi crema habitual. Le doy mis 5 estrellas porque para lo que yo lo quería es inmejorable.

Questo siero è davvero una sorpresa secondo la mia compagna, lei lo utilizza la sera e la mattina si sveglia con una pelle morbidissima e liscia, ne ha provati moltissimi e nessuno aveva dato risultati tangibili, ha detto che questo siero è il migliore che ha mai provato e che lo riprenderà sicuramente.

Using this for about 2 weeks now and can visibly see a difference on my face. My face looks and feels more fresh, smoother and brighter. Buying my second bottle while on offer! Defo a new addition to my skincare routine that I will be continuing. The product is very light feels a bit like water and doesn’t leave a sticky effect.
