I hate to say it because of the price but this is magic in a bottle. My skin was a bit irritated from starting tret and I introduced this serum into my routine. My skin looks incredible. I just got a compliment today that I looked glowing and I was wearing no face make up. It was bare skin and this serum. It does seem like it’s going to last a long time but even if I was going through it quickly I think this is a true holy grail product for me and I’m not going back. It’s forever in my routine.
Star Flower Smoothing Serum
Star Flower Niacinamide Smoothing Serum is a clinically proven 5% Niacinamide treatment powered by micro-pearl technology for visible clarity and calm.

Description
Skin often tells the story of stress fatigue, imbalance, uneven tone. Star Flower Niacinamide Serum was created to restore calm where skin needs it most. Its foundation is scientific precision: a clinically proven 5% Niacinamide concentration paired with innovative micro-pearl technology that keeps actives fresh until the moment they touch your skin.
Each pearl holds a blend of Niacinamide, Hyaluronic Acid, and Star Flower Extract a flower known to thrive in harsh conditions. When the pearls burst, they release a dose of renewal: skin looks smoother, pores appear refined, redness visibly quiets, and hydration returns.
Lightweight and non-sticky, the serum absorbs instantly leaving a finish that feels as calm as it looks luminous. It’s proof that clinical performance and botanical empathy can live in the same formula.
How to Use
Apply 1–2 pumps to clean, dry skin morning and night. Massage until pearls dissolve. Follow with Sun Ritual Mineral SPF30.

Amazing serum!! Live everything this brand makes. We also live that they are clean products!!
Dagan J. 5/5 Verified
I love this stuff! It’s made my skin brighter and softer. The niacinimide in it, along with the Luxury Beauty Serum keep my rosacea at bay! This will be a new subscription for me. It’s also last a long time—I’m just past the second month and there’s a third left—this will probably last me almost 4 months. I put a big drop on my finger, which covers half my face, and another drop covers the other half. You don’t feel any bubbles, so it’s like putting on most serums. It dries really fast. Another Saint Jane item to add to my nightly, and morning schedule. Wonderful serum.

Jessica O. 5/5

Aleigha S. 5/5
I completely obsessed with this serum. I use it all the time now in the cold to hydrate my face. It dries instantly. And it reduces redness and pores. Everyone should use the serum at this point.
Michelle N. 5/5
Ive been struggling with dry skin every winter and this serum has helped my skin so much this time around. Super moisturizing and absord supper fast. Cant recommended enough.
Tuyet T. 5/5
I had high expectations for this product as my goal is to bring some hydration back to my skin. I have combination skin but also dehydrated skin so it's hard to find a product that's going to help me with both and unfortunately, this one brought me nothing. This will be perfect for someone who loves products that feel amazing with no real result at the end of the day
Olivia E. 3/5
I recently got hold of this serum and it feels like a luxury using it every day. The packaging is beautiful looks almost like a perfume and the texture of the serum in the bottle looks beautiful! The serum doesn't have any smell to it whatsoever which i was not expecting as it has flower ingredients but tbh this doesn't bother me. I really like the feel it gives to my skin in the day and at night. I would definitely buy this product again.
Klaudia K. 5/5
LOVE IT! 48 years old with sensitive skin, this serum has been lovely! I was eager to jump on a Niacinamide & Hyaluronic Acid product from Saint Jane. I rarely write reviews but this is deserving. Luxurious, Quality add this to your routine. Bravo Saint Jane, this is going to be a best seller.
Kate P. 5/5
Absolutely gorgeous deep level of hydration and rare star flower ingredient. I discovered Saint Jane after a friend was wearing their SPF and her skin looked amazing.
Jessica D. 5/5
I recently tried Saint Jane's Star Flower Serum, and it's been a game-changer for my skincare routine. It's like a burst of moisture that instantly revitalizes my skin. It's ultra-hydrating without being too thick or sticky, which is a balance that's often hard to find in a serum. It also absorbs so quickly into your skin that you can keep it moving with your normal skincare routine. The pearls are loaded with active ingredients that nourish your skin. If you're on the lookout for a serum that feels weightless, has no scent (perfect for sensitive skin), and leaves your skin feeling incredibly hydrated, Saint Jane's Star Flower Serum is worth a try!
Cassandra H. 5/5

Meredith F. 5/5

Two weeks into using this serum and already my skin texture has improved significantly! Much Brighter. My skin is also very dry on my forehead and always flakey, the Star Flower Serum has kept my face so hydrated and plump! Extremely happy with this product
Janelle M. 5/5
This serum is absolute perfection! The formula is such an amazing consistency as it absorbs into the skin quickly, while leaving you with a glowy finish. Additionally, the niacinamide has been working wonders for my breakouts! It has really helped my skin to fight off acne and leave me with a clearer complexion. Finally, the packaging is so beautiful, such a high end bottle with a good weight to it! Highly recommend
Kieran R. 5/5
I happened upon Saint Jane Beauty at the end of last year, coincidentally when I had just run out of a niacinamide toner that I thought was helping my skin along nicely this Winter. Lately though, I can tell that my products have only been masking that dryness for a few hours. I'm as curious as anyone by nature, and was grateful for the opportunity to receive their new Star Flower Niacinamide Serum. This serum is packed with nutrient-rich botanical actives that aim to give users radiant, hydrated skin. Though I'm familiar with the hyaluronic acid and niacinamide featured in this serum, I've never used anything with star flower, sacred lotus, or beta-glucan on my skin, so I was very much looking forward to seeing how my skin would improve over time. Improve it did; I've always had a bit of texture to my skin from dryness, but now it both looks and feels better after less than a minute of application with a noticeable reduction in any redness I have. (shortened; see Sephora)
Autumn M. 5/5

Sandy P. 5/5
This product is perfect as skin prep for make up application or even just during your skincare routine. It’s non-sticky, lightweight's, and melts away easily! I’ve noticed a change in my skins texture and will keep this in my rotation!I definitely recommend this.
Irma V. 5/5
I recently tried the Star Flower Niacinamide Serum, and it's a skincare gem! The serum's luxurious, lightweight texture absorbs effortlessly without any greasy residue. It glides on smoothly, offering a refreshing feel during application. Star Flower Niacinamide Serum is a must-try for those seeking visible improvements in skin texture and tone. It's become an essential step in my daily routine! Disclosure: I received the product in exchange for this post, but my opinions are genuine.

Brittney C. 5/5
I was gifted this Saint Jane Beauty Star Flower Hydration Serum In exchange for my honest review. Saint Jane Beauty is so luxurious and my skin feels like a million bucks every time I use their products. This Star Flower Hydration Serum is particularly amazing. I love when a product has that little something extra that makes it special and for me, those little micro pearls really are so beautiful. They burst open and add that extra layer of freshness and radiance. Not only that, but it checks all my "beginning stages of aging" skin's boxes by helping to soothe and calm, visibly firm and plump, diminish pores, smooth uneven texture, and significantly brighten and rejuvenate. This serum has been the emergency aid my skin has desperately needed since I hit my 30s, without a doubt.
Blair B. 5/5
I have dry sensitive skin and have been using this for the past few weeks. It’s really hydrating and doesn’t leave a sticky film feeling on my skin and helped reduce the looks of my pores. Will continue to use in my skincare regimen!
