Low molecular, multi-weight Hyaluronic Acid for an intense hydration burst.
Lightweight serum leaves skin plump and supple.
Non-sticky texture glides on like silk and looks like glass.

4D Hyaluronic Acid (HA) will revolutionise the way your skin holds water. Feel the bounce as your skin transforms under the silky veil of our betaine-enriched blend. We've designed this serum to instantly absorb and target each layer as it works to defy the limits of hydration. Four multi-molecular HAs replenish water from the outside and hold water from the inside for plump and supple skin, going deeper and working harder to deliver transformative results that can be felt from the first touch.

Love ST.SAJ
I have been using ST.SAJ since it first launched and my skin has never looked or felt better! I am a post menopausal woman and my skin was so dry before, not anymore, since using ST.SAJ my skin is so hydrated and younger looking and my make-up just glides on now, absolutely love the products and couldn't recommend them highly enough! Everyone needs to be using these products.

Perfect!
I have tried lots of different hylaronic serums and this hands down has been a top pick.. I have always had problematic skin, and st saj products have blown me away - despite my initial skepticism.

ST.SAJ - fantastic products
I have been using this product along with other St.SAJ products for a few months now. You only need a small amount and it feels so nice on my skin. My skin is looking fantastic since using the ST.SAJ products!

Think of it like a BIG drink of water for your skin. Hyaluronic acid (or HA) can hold up to 1000 times its molecular weight in water. Epic, right?! We’ve used four different molecular weights of HA in our HYALURONIC SMOOTHING COMPLEX. One sits close to the surface of your skin to maintain bounce, one sits much deeper to draw in and maintain water then we’ve added a few more in between for good measure!
Yep. HA is a great way to prep your skin for makeup and our formula is packed with betaine and glycerin for the ultimate in long-lasting hydration. Don’t forget to lock it all in place with a moisturiser before you start on your makeup!
Nope. It’s just gonna leave you looking and feeling hydrated to the max. Our science-backed HA complex is all about promoting smooth, plump, dewy skin.
Yep. ST.SAJ is proudly registered with the Australian Made Campaign Ltd. We're excited to rock the iconic Australian Made logo on our packaging!
Yes! The entire debut collection of ST.SAJ products is safe for breastfeeding women and those who are pregnant (do not apply products directly to the breast).

We’re all about working with your skin, not against it. That’s why we only recommend cleansing at night. While you sleep, your skin is busy doing its thing: repairing, replenishing, and building up a healthy, protective acid mantle. This magical overnight process leaves your skin coated in natural oils and nutrients that keep it hydrated, balanced, and glowing. Cleansing in the morning can strip away all that overnight goodness, leaving your skin less protected and more prone to dryness or irritation. We recommend rinsing your face with water in the morning, then go straight in with your essences, serums, moisturiser and fave SPF.
We proudly offer Free Shipping on all Australian orders over $99.
Shipping on Australian orders under $99 is a flat rate of $10.00. We also offer express shipping for those that need their skincare in a hurry!
Yes, we do. See our shipping rates at checkout if you are one of our amazing friends abroad.
Please check our Returns Policy for information on returns.
If you believe you’ve had an allergic reaction to a ST.SAJ product, please email glow@stsaj.com straight away. Stop using the product for now, but don’t throw it away. If you’ve used less than 20% off the product we can discuss a refund after our team assesses the images of your reaction.
The clever people at Chemist Warehouse know a good thing when they try it. That's why we're thrilled to announce our partnership with the home of Australian skincare. Head down to Chemist Warehouse in South Wharf DFO (Melbourne), where you can touch, smell, try and buy the entire ST.SAJ range for yourself. Or shop online here or at Chemist Warehouse now!
