The Fab Four

As a dermatologist, I am con­fronted every day with issues that are visible on the sur­face, but whose so­lution often re­quires a look be­neath the sur­face, to where the indivi­dual skin cells com­muni­cate with each other.

Meine Moti­vation: Wenn in der Tiefe der Haut das zel­luläre Gleich­gewicht stimmt, stimmt es auch an der Ober­fläche – das vir­tuelle Gesicht meiner Marke ist also das »glück­liche Leben« einer jeden Haut­zelle in einem har­monischen Umfeld, in dem alle Haut­zellen fein auf­einander abgestimmt und koor­diniert ihren Auf­gaben nach gehen können. Neben den Merkel­zellen, spe­ziellen Sinnes­zellen in der Ober­haut, die für Druck- und Tast­empfindungen ver­antwortlich sind, gibt es 4 wichtige Zell­arten in der Haut, die ich hier kurz und ver­einfacht dar­stellen möchte.

Cell 1/4 The Producer

In the eng­ine room of the skin, the dermis, a relatively un­explored cell, the fibro­blast, calls the shots. It pro­duces col­lagen, hyaluronic acid and many other sub­stances. The acti­vity of the fibro­blast deter­mines the tension, expression and even­ness of the skin.

Cell 2/4 The Colourist

Our skin colour is deter­mined by the pre­sence and activity of pigment cells (melano­cytes). All people, regard­less of skin colour, have approxi­mately the same number and distri­bution of melano­cytes. Differences in skin colour re­present differen­ces in the den­sity and size of the pig­ment granules. Melano­cytes produce the brown pig­ment of our skin, melanin, which is distri­buted to the cells in the environ­ment so that they can pro­tect the sensi­tive DNA from the harm­ful effects of UV light (sun).

Cell 3/4 The Immunologist

One of the most important cells for our health is the Langer­hans cell, which was dis­covered as early as 1867 by a medical student (Paul Langerhans). It lies in an extensive net­work directly under the sur­face of the skin and uses its ten­tacles (dendrites) to catch for­eign bodies that enter the skin. It eats these and travels with them to the nearest lymph node to present them to the immune system. Its in­credible achieve­ment is to encode the for­eign bodies in such a way that our immune system understands that they are for­eign bodies. Only when the immune system has under­stood this can a tar­geted and effective fight against the invaders begin. We must be grateful to our skin that it has such a network of intel­ligent protective cells.

Cell 4/4 The Bodyguard

The covering cells (keratinocytes) of the epidermis are the most impor­tant buil­ding blocks of our body shell. They lie next to each other in a closed band­age that is com­plet­ely renewed once every 4 weeks. We could give every person in this world a covering cell of ours and still have some, i.e. we have many bil­lions of these cells. Every day we lose many millions of them without even noticing it. Good skin care helps the covering cells to do their most important job, which is to maintain a protect­ive barrier and thus prevent valu­able sub­stances from being lost or harm­ful substances from pene­trating our skin.

Cell biology is fascinating and the beauty of the cells shown here is capti­vating. Their harmon­ious inter­action is the linch­pin of healthy skin and thus also the core of vita­lity, radi­ance and beauty.
