Having fairer skin has subconsciously become the standard of beauty in this modern era.

For most Asian women, a porcelain-like white face is the feminine ideal. They will go to great lengths to avoid the sun – fighting to preserve or enhance their pale complexions with expensive creams, masks, gloves, professional face scrubs and medical procedures. ‘Whitening’ or more accurately skin lightening products are also known as bleaching creams, whiteners and skin brighteners, which work by reducing a pigment called melanin in our skin.
Melanin determines the colour of our hair, eyes and skin. Therefore, people with more melanin will have a darker skin tone. And tyrosinase is a type of enzyme that controls the production rate of melanin. The common uses of lightening products are to treat age spots, acne scars, or discoloration related to hormones.
Dr Paul Chia, Specialist in Dermatology & Consultant, Raffles Skin & Aesthetics, sheds some light on decoding some of the common ingredients in whitening products, and dispenses tips on how we can achieve naturally brighter skin.

It is derived from cranberry, blueberry and bearberry leaves. Arbutin acts by competitively inhibiting tyrosinase and inhibiting melanosome maturation
This naturally occurring dicarboxylic acid is derived from a lipophilic yeast called pityrosporum ovale. It works by inhibiting tyrosinase.
It is an alpha-hydroxy acid (AHA) derived from sugarcane. In low concentrations, glycolic acid produces desquamation of pigmented skin cells. About 30 to 70 per cent of glycolic acid can enhance the penetration of other skin lighteners such as HQ.
This hinders tyrosinase and is found in the Aspergillus oryzae fungus. It is used as a skin-lightening agent in concentrations of one to four per cent.

They contain enzymes that reduce melanin transfer, and soy has proven to be both efficacious and safe.
This is popularly included because it interferes with pigment production, which leads to hindering tyrosinase activity. Magnesium L-ascorbic acid 2-phosphate (MAP) is a stable Vitamin C derivative and has shown to lighten pigmentation.
The use of natural ingredients for skin-lightening has gained popularity because ‘natural’ products are often perceived as safer alternatives. Ingredients such as arbutin, azelaic acid, glycolic acid, kojic acid, licorice extract (glabridin), mequinol, paper mulberry, soy, vitamin C, niacinamide, and melatonin are natural agents used to induce hypopigmentation.
