Reasons?
In a Review of 45 patients with Dark Under-eye circles,
• 35% had Chronic Allergy or sinus disease.
• 2% were Chronic eye rubbers
• 54% had family history of dark eye circles
• 82% had prominent Vascular component

Exclude Anatomical causes:
• Hollow eyes-Lack of fat around the eyeball so the eye is buried
deep inside the orbit.
• Arcus Marginalis deformity-This tissue holds the lower eyelid
skin to the orbital bone. If too tight, it causes the skin of the
lower lid above the Arcus to fall over & downwards creating a
deep shadow under the lower eye-lid.
Can present in childhood & is hereditary.
This shadow follows the lower eye-lid.

Exclude Anatomical causes:
• Tear Trough deformity-Presents in the 40-50 year group. Occurs
due to loss of Malar fat on the cheek bones & descent of Skin &
fat pad .It is much lower than Arcus ring and tends to continue
over the cheek bone.
• Periorbital melanosis (pigmentary demarcation lines) ;
presents as a sharp line between pigmented & light skin
& continue over the cheeks.
STUDY-In 1033 women in Saudi Arabia, 144(14%) had at least one facial (PDL) line with onset at age 16.

Exclude other Medical conditions:
• Nasal or Sinus congestion -Blocked nose, Nasal discharge,
Mouth-breathing patients causes blockage of venous drainage
of under-eye skin leading to congested veins which are visible
through thin, translucent skin.
• Iron deficiency &Hypothyroidism
• Inflammation of skin-Contact eczema, Lupus or Lichen Planus,
which can all cause itching & chronic rubbing.

XANTHUMOL 3% (Humulus Lupulus ext)
• Prevents Release of Cytokine (GM-CSF-Granulocyte
macrophage colony stimulating factor) in response to
UVA&UVB which activates Melanocytes.

20 Patient split face study on Melasma patients in Egypt showed a
70% improvement while only 20% improvement on control side of
face using Liquertin twice daily.

ADVANCED GLYCATION END PRODUCTS (AGEs) &
RECEPTOR (RAGES)
Other than oxidation creating ROS(Reactive oxygen species ie
oxygen atom with a missing electron) & Matrix Mettaloproteinases
(MMPs) there is a very important mechanism causing Ageing.
AGEs are produced when sugar non-enzymically binds to proteins
& lipids eg collagen and elastin in skin.
They activate the Receptor for AGEs called RAGES.
Pharmaclinix.com
ADVANCED GLYCATION END PRODUCTS (AGEs) &
RECEPTOR (RAGES)
AGE bound RAGEs stimulate Nuclear factor –kB & blocks NO
(Nitric oxide) activity leading to increased permeability to
macro-molecules of blood vessels.
This results in up-regulation of Inflammation & tissue destructive
mechanisms in Euglycaemic patients in Ageing.

• Competes with Adenosine for Adrenergic receptors on the skin
under the eyes to cause vasoconstriction. This constriction
reduces the leakage of skin capillaries in the skin under the
eyes-reducing puffiness.

• Easily absorbed into skin
