Your skin is a barrier. Care for it from the outside and from within.
A stressed skin becomes a barrier, so even an expensive cream disappoints. Working from within only counts if what you swallow reaches the cell. That is where ABSORPTIX® comes in.
Three actives, one capsule a day.
Stated per capsule, delivered with ABSORPTIX® to the skin cell.
What stands between a good ingredient and your skin cell.
Six barriers between the capsule and your cells.
Formulated with doctors and pharmacists, followed in the clinic.
The skin forms a barrier. We get through it with peelings and lasers, but also from within.

Frequently asked questions.
What does ‘from within’ actually mean?
Creams work from the outside. A supplement supplies the skin through the bloodstream, provided its ingredients survive digestion. ABSORPTIX® is built to make sure they do.
Does SKIN FUEL™ replace peelings, lasers or sun protection?
No. Dr. Argento combines both: treatments and protection from the outside, SKIN FUEL™ from within. The two reinforce each other.
What is ABSORPTIX®?
BRONN's patented formulation logic (BE 2026 / 7260): every ingredient gets its own transport route and the energy to be taken in, so it reaches the cell.
What is inside SKIN FUEL™?

Skin renews in cycles of about four weeks. Count on at least three of them, around 90 days. The 2+1 bundle covers exactly that window.
