Jan Marini Skin Research C-ESTA Serum - Antioxidant-Rich Beauty Product for Dry, Oily & Normal/Combo Skin - Lifting & Firming Serum with Vitamin C - 1 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 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.

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

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 🥰

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!

Definitly makes my skin more clear.

I am a licensed esthetician and this is one of my favorite Vitamin C formulas. It is a gentle, yet effective form of Vitamin C. I have combo, acne-prone and sensitive skin. It has a bit of a floral scent that I ended up getting used to.

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.
