about our complete serum


The base of this powerful serum is 15 x concentrated cross-linked high molecular weight hyaluronic acid – a super-ingredient which can hold up to 15 000 times its weight in water which is then gradually delivered into the skin for day-long hydration while softening fine lines and providing an immediate plumping up effect on the skin.  But this is no short-term fix, it is specifically designed to give you deep, long-term results.

(I think of it a Beau-tox.  A booster in a bottle – no needles required.)

Overflowing with peptides which both relax as well as smooth wrinkles while rebuilding the main framework of the skin, this is the product our frown lines and crow’s feet will love.

This is our healthy ageing powerhouse.

With high concentrations of Niacinamide and Resveratrol, the serum offers a powerful antioxidant defense against free radicals from pollution, as well as those damaging UV rays … all this while brightening the skin and regulating oil overproduction. There is a reason we have called it the Complete Serum!

*The colour, scent and texture of our products may vary owing to natural compounds used.

Our exclusive complex of Chlorophyll, Malachite, Curcumin and Spirulina lightens sun spots and improves skin texture. Nothing short of extraordinary.

How to Use


Apply one pump of product to clean, still damp skin on the face, neck and décolletage. Wait thirty seconds for the serum to be absorbed before applying the Eye Crème Solution followed by the Face Crème Originale. Use this hyaluronic acid serum morning and night before applying oils or heavier creams. Pay particular attention to those areas of the face developing fine lines and wrinkles.


what people are saying

“This one is more of a cardinal rule than a tip … hyaluronic acid is a water-grabbing humectant holding up to 1000 times its weight in water (and root 4 uses a 15 x concentrated HA with even greater humectant properties) so it is important to layer it with a moisture-rich cream for longer-lasting firmer, hydrated skin. Apply to damp skin and seal off with a moisturizing cream or oil.”

The absolute best!

This is the best serum ever. Leaves your skin feeling clearer, softer and just amazing. After trying out so many serums before, I will won’t be changing. I’ve always battled with my skin and this range and serum WORKS! Thank you Root 4!

Best ever

Love this silky soft serum, my skin has never looked better since using the whole Root 4 range.

The best on the market and I tried them all

This serum has saved my skin. After countless alternative products I have tried and money wasted, I have finally come across the only serum I will ever need. Literally nothing I have tried before compares to how this serums nourishes my skin and leaves it feeling soft and smooth. My redness has gone down and my acne is so much better since I started using this product. I can only recommend it for everyone to add to their skin routine.

This product will become your next "go to" serum

Once you have tried this serum you will view it as a necessity rather than a luxury. It has changed my skin texture for the better. Also cleared my acne. I absolutely love the fact that I am applying antioxidants to my skin. It's also anti-aging so it addresses many of my concern relating to aging skin. Thank you Dr. Vanessa for this amazing serum!!
