I've been using this for two weeks as my only moisturizer. I have really dry skin and I absolutely love the way it makes my face feel. All my dry skin has disappeared.
Sweetgrass Nº 1 · Active Oil Serum
Ancient Medicine for Modern Skin
Every formula starts
Every formula starts
with the land.
The Northern Plains tribes have used sweetgrass, sage, cedar, and echinacea as medicine for centuries. Not as trend ingredients. As the foundation of how they cared for their skin and their people. TATANGA starts there.
Every formula begins with wild Montana botanicals, slow-macerated directly into the oil. Then we add plant-derived actives that modern skin science says actually work. Every ingredient comes from the earth. Ancient tradition and modern precision in the same bottle.

The Process
The actual plant.
The actual plant.
In the actual oil.
No extract. No shortcut. The whole plant, submerged and drawn out by heat and time. This is how plant medicine has always been made.
Montana
What they said.
What they said.
Real people. Real results.
The texture is really light and it didn't irritate my skin at all. I deal with eczema and after about three weeks the flaking and redness had pretty much gone away. My skin feels calmer than it has in years.
After a bad reaction a few years ago my skin has been so sensitive that almost everything irritates it. This is the first thing I've put on my face that didn't burn or flare up. It actually made my skin feel softer and calm.
