Pioneered with NASA Zero Gravity Sciences Technology
Made with 3D Botanical Stem Cells
No Added Fragrance
This Face Serum incorporates revolutionary 3D stem cells created in a biomimetic suspension rich in growth factors, cytokines, proteins and other bio molecules to replenish the skin, improve hydration, firmness and elasticity.
It features polyglutamic acid (PGA) and is a next-generation moisture-binding formula that helps skin retain water at the surface — outperforming many conventional humectants in both depth and duration of hydration. Paired with multi-molecular hyaluronic complexes, botanical extracts, and targeted actives, our Celestii™ Face Serum is formulated to deliver visible, lasting results.
After cleansing, pat skin dry. Massage a small amount over the face, neck, and décolleté until absorbed. Follow with moisturizer.
It's out of this world! Powered by biomimetic technology, this Face Serum was inspired by zero-gravity research where skin-supporting bio-molecules thrive. This nutrient-dense serum helps visibly smooth wrinkles, boost elasticity, and deeply hydrate for a plumper, more radiant complexion. Clinically shown to deliver real results, it supports your skin’s natural renewal process for a firmer, smoother, glow-from-within look.

The reason I give this product 5*'s is because I noticed the difference in my skin (face) the next day!! I use this product as part of my morning and evening routine every day! It is a must for fine lines and wrinkles! My dermatologist noticed the care I am taking with my skin...yay!!! Not bad for a 71 yr old!
Just ordered my second tube. People are telling me my skin looks great! No one has ever told me that. I’m 63 years old and when I wake and look in the mirror there is a difference..may I dare say DEWY! Also notice my under eyes are not as dark. I’m using along with the Vitamin C line and couldn’t be happier. I was excited for this NASA Technology product and it’s stellar! Did not disappoint! Highly recommend
I have dermitis, and psorias on my face. Over the course of 3-4 weeks this product has made it almost invisable along with the vitimian C products. Love Naples Soap Company!!
using Celestii seems to be clearing m y face of rosasea blemishes . I have not yet finished the first bottle . It recommends using moisturizing lotion after application.
I am using Face Cream which seems to have added softness. Before using the Face Cream ... one of my friends actually noticed a difference in my face .... which made me feel confident in using the right thing. One downside . I love the liquidity of the lotion , rather than having it as a cream ... but the bottle stands >"on the opening" .... when you get lotion on your fingers , you need to stand it up so more will not flow out when you lay it flat ... while putting on your face. Maybe a stand up bottle will be better with opening on top ....
Thank you Naples
This is amazing! Light and not greasy sets in and makes your skin feel tighter. I also add moisturizer on top of it and it helps it set in and leaves your skin feeling soft and moisturized. We have bought 5! My son who plays football uses it to help his face stay nice after long practice and sweating!
I’ve only been using it for a week, so I haven’t had enough time to notice any change in my skin’s appearance. Other Naples Soap Company products I’ve used over the years have been very effective for me, so I’m hoping this one continues that trend. The product is very lightweight in texture, applies easily and smoothly, absorbs quickly, and is (hallelujah!) fragrance free.
Celestii Serum has done wonders for my skin tone! My face feels tighter, smoother, and looks more polished. I use it day and night, especially under my eyes, and I love the results
Love the texture. It dries quick & is smooth, not sticky. My skin likes it. I’ll keep using.
Thanks for always looking at new technologies to help improve our beauty health. Well done!
I have jsut started using this . It is soft clear liquid and one issue is that it comes from the bottle too quickly ... so I've learned to put some on my finger and quickly stand the tip up .
I am anxious to see how it will improve my facial skin / rosacea in the coming weeks.
Happy for this opportunity .
I have used this face serum for almost two weeks and there is a noticeable difference. The serum feels good on application and absorbs well. Definitely recommend this product!
