The skin lightening effects of Kojic Acid Soap
Kojic Acid is an excellent skin lightening ingredient in both food and cosmetic products; however, being an acid it is imperative that its use is monitored carefully in the cosmetic industry so as to prevent any side effects. The manufacture of Kojic Acid is found in certain types of fungi, and also as a by-product in the fermentation process when making the Japanese rice wine, known as sake, and in the soy sauce industry. In the food industry it serves as a preservative, whereas in the cosmetic industry its main function is to lighten skin where various skin conditions have left the skin discoloured such as in acne scarring, sun damage spots and dark spots caused by aging. In cosmetic products Kojic Acid is included as an ingredient in creams, lotions, soaps and face masks used in the skin lightening process. It is important for any person wanting to use these amazing products to first consult a dermatologist to ensure that Kojic Acid products are the correct products to use in that person’s particular skin condition.
The active ingredient in Kojic Acid prevents the formation of tyrosine, the amino acid that is required for the skin to produce melanin. Once tyrosine is eliminated from the skin, then melanin production ceases and Kojic Acid will aid in the skin’s lightening process. Only a very small amount of Kojic Acid is necessary and the dilution in all skin products is in the region of 1 to 2%. A higher concentration would probably result in rather unpleasant side effects such as contact dermatitis, itching, rashes and other side effects which could be painful. Even using a low 1-2% concentration can cause side effects, but generally this would manifest as slight tingling or burning which should subside after a short time. However, should there be any side effects which are constant, the use of Kojic Acid products must bediscontinued immediately. Any irritation can be soothed by using a hydrocortisone over-the-counter cream.
Ideally Kojic Acid Soap is the first product to try for hyperpigmentation, acne scarring, dark spots and even freckles.
It helps to exfoliate the skin leaving the skin smoother, while at the same time preventing skin darkening by reducing melanin production. The moisturising properties of coconut oil aid in the absorption of Kojic Acid, and with added Vitamin C and natural sweet orange extract the lightening properties are enhanced.
The value of vitamin c
The value of added Vitamin C has many other advantages besides its lightening properties. Vitamin C boosts the production of collagen, thus smoothing wrinkles as it evens out skin tone and reduces redness; being an anti-oxidant it helps protect the skin from sun damage
together with regular sunscreen applications; it speeds up the healing process and reduces inflammatory conditions and improves hydration and moisture retention.
Using Kojic Acid Soaps
It is important to use Kojic Acid soap correctly so as to avoid any complications or side effects. The latter may appear as tingling, itchiness, rashes or any other form of contact dermatitis. If the reaction is severe, and if pain is part of this, then discontinue using the product immediately. Before applying Kojic Acid soap to your face, it should be mixed with water – massage the soap solution gently into the facial and neck skin and leave this on for no more than 30 seconds. Rinse off with cold water to close the pores and dry gently with a towel. Apply a moisturising cream as this soap can have a drying effect on your skin. Initially you may feel some tingling, but your skin will adjust to this, and as time goes on the amount of time the soap can be left on your skin can be increased to three to five minutes. Start off soaping once a day and then when you no longer have any side effects such as tingling, then increase use to twice a day.
Your skin may feel dry after using the soap, so use a good water-based moisturising cream after soaping. It is preferable not to expose your face to the sun but if you intend going into the sun, always apply a sun screen and wear a hat to protect your lightening skin from the sun’s rays. The use of lightening products makes your skin very sensitive and thus more likely to get sun-damaged as the level of protective melanin has been reduced. In general, the longer you use the soap, the lighter your skin will become. Be patient as it will take many weeks, at least eight, before you see a significant change in your skin tone. Ideally the recommended time span for using Kojic Acid soap is four months.
