Jan Marini Skin Research C-ESTA® Face Serum - 1.0 Fl Oz

I'm 35 and have been seeing an esthetician for several years who carries Jan Marini's skincare line. She uses this C-Esta Serum during my monthly facial, and it is so amazing for brightening my complexion and giving me smooth, even, dewy, radiant skin! Buying a bottle of this product was a splurge for me. It's typically around 100 bucks, which is more than I want to spend on a single skincare product. However, I couldn't refuse Jan Marini's 20% off Black Friday sale here. I bought it directly from Amazon, not a third-party seller, and the product is perfectly fine, smells right, has the correct consistency, etc., exactly the same as what I've purchased from my esthetician over the years (and yes, sometimes it's grainy). C-Esta really does lift and tighten. I always notice in the bathroom mirror how my pores appear smaller a few minutes after applying this serum. The dispenser pump works well. A bottle lasts me several months. The product is indeed watery in consistency and smells a bit like flowers + tropical fruit. It's hard to describe, but it smells amazing. Really happy to have scored this for a discount.

I LOVE Jan Marini! Everything about their skin care line is excellent. This hydrating serum is amazing and helps me look younger as well as doesn’t cause breakouts. It’s smooth and sheer and for someone like me who lives in the desert this product is a miracle! I even get away with a few more weeks between Botox with their regimen. Love it!

Excellent. Using it for years. A Medical Spa recommended. It's expensive for the small amount but lasts a few months.

I also have used this product several times in combination with my facials. I actually like it. My skin looks good. Healthy doesn’t affect my make up. Doesn’t affect other products that I might wanna wear. If you haven’t tried it you might want to.

This serum is amazing! My fav vitamin c serum. I use a lot of Jan Marini products and in combination with others it completes my skincare routine 🥰

Been using this product for 20 years. As a skincare specialist, I recommend C-Esta Serum for daily use. A silky feel and a visibly brightener skin.

A good serum. Expensive, but my skin looks great.

I first purchased the kit from my dermatologist. When I saw that Amazon offers it too, I decided to purchase the products here because of the convenience. Price is the same but I get it delivered to my front door. Do you want to know if it works? Well, judge for yourself. This picture (for work) is me after 6 months of using the product. BTW, I turned 75 in December.

Highly recommended

The C-Esta Face serum had a faulty pump. I got about 6 dispenses from it before it failed. I messaged the supplier via Amazon to enquire about returning it for a replacement but as yet have had no response I would give it no stars if it were possible because whilst I know the product is good - I've been using it for a while - the packaging has changed and is unreliable and so I am unable to access this expensive product

Amazing product. My facial skin much improved and looks healthier

The product arrived in an open box without a lid attached. Its a disgrace for a customer to receive a premium cream like this packed like trash!
