Very Healing

Last year I had an infected area on my forehead about the size of a ten cent piece that frustratingly would not heal. Over the course of about 9 months I tried various products to heal the area beginning with natural gentle products then in desperation trying Savlon, Betadine and harsher products. The infection continued - red and weeping. I then tried the BIOMEBALANCE Phyaluronic Serum slathered on the wound morning and night and nothing else. Within four days the wound had dried considerably and wasn't hot nor sore anymore. Within two weeks the wound had completely healed, no trace of it. A year on and still the area shows no sign of the infection. Quite amazing.

Thank you Pia and Team.

Smooth and Refreshing

My very sensitive skin has reacted to every moisturising facial product... until I tried Phyco Health's magical Biomebalance serum. It leaves my skin feeling amazingly refreshed and oh so lovely and smooth.

I also love that it's an Australian innovative product made from naturally abundant resources.

I'm about to try the Nourish range.

Amazing serum

I have found this serum hydrating and non irritating as I find most serums I use on my face make me break out!

This one didn’t it actually had the opposite affect by calming my reactionary skin!

Highly recommend this serum
