Kojic acid is often used topically to treat a number of different cosmetic conditions. It's been approved for use in cosmetic products in concentrations of 1 percent or less. It's most often used as a skin-lightening agent.
Skin bleaching is the act of using steroid- and chemical-containing products to lighten the skin. Hydroquinone and kojic acid are often used in skin bleaching creams.
Researchers found Niacinamide is an important ingredient in skin lightening, which works to stop the transfer of melanin pigment (responsible for the darkening of the skin) to skin cells (keratinocyte). Niacinamide decreases hyperpigmentation and lightens skin gradually after using it for a long duration.
It is impossible to change your constitutional skin tone. However, it is possible to medically treat concerns like tan, dark spots and post-acne pigmentation with safe and effective skin lightening solutions. These advanced aesthetic treatments can improve the health of your skin and restore its natural glow.
Kojic acid is not cytotoxic (that is not harmful to living cells) and therefore cannot permanently lighten your skin tone. However, you can enjoy the results as long as kojic acid or kojic acid dipalmitate are used.
For as long as kojic acid skincare is used, a person's natural skin tone can be lightened. This brightness will not reverse as soon as you stop using kojic acid skincare, but instead will take months to return.
Chemical peels, laser therapy, microdermabrasion, or dermabrasion are all options that work similarly to rid skin of hyperpigmentation. These procedures work to gently remove the top layer of your skin where the dark spots lie.
There is no safe or reliable way to lighten someone's skin tone. Products or DIY recipes that claim to do so carry numerous risks. Even legal and over-the-counter options, such as hydroquinone creams, can sometimes lead to permanent discoloration.
Green tea is known to have antioxidants, to reduce redness and lighten skin tone. Method:Rice flour mixed with aloe vera extracts makes a soft gel and can be applied to your face as a face mask. First, put the mask on your face, wait for it to dry, and wash with cold water. Then, apply the mask once a week.
Answer: Skin Lightening without bleaching
The safest approach is to use sunscreen multiple times daily to prevent any sun related pigmentation and to use mild agents like glycolic acid, vitamin C, or other fruit acids to help exfoliate the skin and help even out pigmentation.
You can use topical products to lighten your skin. These products reduce melanin and are commercially available. Prescription or over-the-counter skin lightening products often have the following ingredients: hydroquinone, kojic acid, vitamin C, glycolic acid, azelaic acid, retinoid.
Skin Bleaching Creams are Not Permanent
The truth is skin bleaching creams do not get rid of the melanin permanently. This is because the skin is constantly being renewed, and this includes formation of new melanin by melanin-producing cells known as melanocytes.
As per studies, products with Hydroquinone, Vitamin C, Kojic acid, glycolic acid, azelaic acid, retinoid, and many more ingredients with tyrosinase suppression properties are preferred. They help in slowing down melanin production. And eventually reducing it.
Vitamin C is a naturally occurring substance and an essential nutrient. It has various biological and pharmaceutical functions. It inhibits melanin synthesis through downregulation of tyrosinase enzyme activity.
Use of strong oxidizing agents, such as permanganate, chlorate, chromic acid, peroxide, and peracetic acid, will bleach melanin, although the process is slow, taking 16 hours. The blacker the melanin, the longer the bleach takes to decolorize the pigment.
In the clinical studies, niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use.
