6 Benefits Of Lemon In Cosmetics.


1) The effectiveness of lemon juice in the treatment of acne.

Lemon juice, averaging around 2 on the pH scale, is acidic and the low pH is responsible for the fruit's sour taste as well as the juice's acne-fighting properties. Citric acid is the main acid present in lemon juice although ascorbic acid, also known as vitamin C, and malic acid are also present in smaller quantities. The antibacterial properties of the acids present in lemon juice makes them effective for use in acne treatment due to their ability to kill acne-causing bacteria such as Propionibacterium acnes and Staphylococcus epidermidis that infect skin pores and cause breakouts of spots. Aside from its antibacterial properties lemon juice helps to cleanse the skin of grease, dirt and dead skin cells that can clog up pores leading to blackheads and whiteheads. Essential oils found in lemons are also effective against acne by inhibiting P. acnes residing in pores and reducing inflammation caused by immunological responses.

2) Hair-lightening lemon juice provides an alternative to synthetic bleaching agents.

The hair-bleaching properties of the sun are well-known, caused by the destruction of melanin in the hair resulting in lighter pigmentation, and this bleaching process can be hastened by the application of lemon juice to the hair. The manner in which lemon juice speeds up the bleaching of hair by the sun is through the chemical reduction-oxidation reaction, or redox, whereby the chemicals present in lemon juice help the UV light alter the molecular structure of melanin via the transfer of electrons breaking down double molecular bonds into single molecular bonds. The sun's heat opens hair cuticles enabling the lemon juice to penetrate the hair and assist the redox of melanin. To prevent drying hair out it is advisable that the lemon juice is used sparingly, that is lightly sprinkled or sprayed rather than soaked, and at not too high a concentration while the use of certain oils can help moisturise the hair.
