What is SEPI WHITE MSH?
Sepiwhite MSH also know as Undecylenoyl Phenylalanine is an excellent skin lightener and brightener suitable for all skin types and ethnicities that promotes a more uniform and radiant complexion with results in as little as seven days. Studies have demonstrated an increase in skin luminosity and decrease in the number and color of hyperpigmented spots, and it can be combined with other active ingredients, such as niacinamide or AHAs. Sepiwhite MSH is a lipoaminoacid or vectorized essential amino acid developed from phenylalanine, an amino acid involved in melanin synthesis. MSH is an alpha-melanocyte-stimulating hormone (MSH) receptor agonist developed from this amino acid that inhibits the process of melanin synthesis from the hypothalamus to produce a reduction in melanic pigments in skin cells.
It is a well-known and well-recognised skin lightening ingredient. Unlike other skin lightening actives, it produces a faster skin lightening response in most users.
This particular ingredient is recognised by dermatologists as one of the safest and most effective alternatives to hydroquinone. A variety of in-vivo tests have proven it's effect in controlling hyper-pigmentation in people of all skin tones. It is an oil-soluble compound.
