Formation of melanin (brown spots) is entirely dependent on UVR exposure and stimulated by UVR. The enzyme, tyrosinase plays a key role in melanin synthesis. Tyrosinase needs an oxidizing atmosphere to work, that’s why antioxidants (in skin care) are so good.
Melasma is a skin pigmentation that masks the face in pigmented mascules usually seen across the forehead, cheeks, chin and upper lip. A genetic disposition is a major factor in the development of melasma and of course sun exposure. It has been researched that more than 30% of people will have a family history of melasma.
It is a hormonal pigmentation that can be caused by:
– Pregnancy
– Mild ovarian or thyroid dysfunction
– Contraceptive Pill and
– Some photosensitizing medications
Melasma will often fade after pregnancy or when the contraceptive pill is discontinued. If there is a repeated and extensive sun exposure, pregnancy or contraceptive pill, the original melasma will return in its original form, therefore continued and complete sun protection is required to prevent future occurrence.
Again, we need to inhibit the enzyme tyrosinase. If you can block tyrosinase, you reduce the formation of pigment granules, melanin, and achieve a skin lightening affect. Dermaviduals concentrates Complexion Care Liposomes and Plant Liposome Concentrate along with Vitamin B and Vitamin C can be put in your daily moisturizer to protect your skin from pigmenting or can be used as a neat (directly on your skin) application.
Protect, protect, protect and prevent then enjoy the summer!
