fading concerns

Recommended Posts

There are detailed threads on this subject.. search for a member called HatingHats, a biomedical engineer who has written extensively on the matter. I have pasted below a reply he gave to an almost identical question a few months back. Hope it helps: Please bear in mind this answer is specifically true for the pigments that HIS use... pigments that have been developed by HIS over years.



pigments are held in the collagen micro-forest of the second layer of
your skin (the dermal layer).  Imagine trying to hold some mayonnaise in a
cross weaved salad bowl made out of thatching. At first, the salad bowl
will hold a big lump of mayonnaise just fine. However, as time passes,
the mayonnaise can leak out a bit from the bottom as Earth's natural
gravitational field presses down on the mayonnaise (equal to 9.81 m/s^2)
and because the mayonnaise degrades a little bit. (its viscosity
changes as the UV radiation from the sun changes its chemical structure)
The same is true of the pigment being held in a client's collagen
micro-forest, and normally, it would leak out into surrounding tissue
and bleed out, so to speak. However, the reason this does not happen is
that your immune system constantly removes particles that float free
from the collagen microforest. (and from there are removed to the lymph
nodes) Therefore, with regard to SMP, there is almost no "bleeding".
There is fading, where a more densely packed area over time degrades due
to immune response or UV radiation, but there is not bleeding or

     Your next question is probably, "Then why do regular tattoos
seem to bleed and merge after many years?"  The answer to that is that
regular tattoo inks are exactly that, ...inks. (they are not monomeric
pigments) They are made of the pigment molecules but are usually
combined with binders, carriers or additives. When that tattoo ink is
subjected to the UV radiation of the sun for many years and Earth's
standard gravitational field, the various components' are separated or
their covalent bonds are broken and they break down and "bleed out", but
at separate rates, which show as a stain bleeding together, or as a
smearing. All the while, the immune system is working to remove this
degradation. In comparison, the HIS pigment is a monomeric structure
that does not break down any further, which is why you do not see a
bleeding or smearing. The only thing you see with HIS is fading.

      Then, your next question is likely to be, "Will the individual
dots eventually fade away?"  The answer is yes. If given enough time,
the dots will fade down until they are no longer distinct dots (at least
from an observer's point of view). And, that is the exact reason why
all clients, at some point in the future will need an occasional
touch-up. It is so new sharp dots can be laid down which keep the
appearance ultra-realistic. For some, this might be every four years,
but for another, it might be once every eight years. (I would say the
average is about once every five years)
