What independent lab testing found
-
Up to 3x
Our technology penetrated skin's outer layer up to 3x more effectively than a standard body lotion, at every depth measured.*
-
41% more hydration
41% higher hydration in the outer layer than a standard lotion, and more than double untreated skin, after a single application.*
-
Deeper, not just more
The tracked active traveled further into the outer layer instead of pooling near the surface. Lab imaging showed a visibly denser band of moisture inside the skin.*

Questions, answered
What is Mini Molecule Technology™?
Rich moisturizers like petrolatum are made of large molecules that sit on top of skin. Our proprietary Mini Molecule Technology™ breaks them into ultra-small molecules that travel past the surface, into the layers where dryness actually starts. In independent lab testing it carried moisture up to 3x deeper than a standard body lotion.*
Serum or lotion? Where do I start?
Both, if you can. Down Deep HA Body Serum goes on first to target deeper into the skin barrier; Down Deep Body Lotion goes on second to lock in moisture. If you're picking one: lotion for dry, tight, flaky skin; serum for dull, dehydrated skin that wants a lighter feel.
Is it safe for sensitive skin?
Yes. Every formula is dermatologist-tested and tested on sensitive skin, with no dyes, phthalates or sulfates. Both products come fragrance-free.
Will it feel greasy or stick to my clothes?
No. Both absorb in seconds and leave no film. Velvety, weightless, skin soft to the touch, dressed right away.
