Though most of the users vouch for the effectiveness of skin bleaching pills, there are some speculations about the possible side effects. In fact, there is no scientific backing for the effectiveness of these whitening products. According to some health experts, oral use of glutathione may not be effective, as the body may fail to absorb it properly. It is also contended that it is better to use supplements with amino acids that are required for the synthesis of glutathione, instead of taking glutathione directly. It has also been suggested that intravenous use of glutathione is more beneficial than the pill form.
Glutathione is believed to be the most effective antioxidant, immune system booster, and detoxifier, that is produced by the body. It can neutralize the negative effects of free radicals, that can accumulate in cells. It can detoxify the body by helping organs, like the liver, in eliminating toxins. It is said that, people suffering from serious medical conditions, like cancer and AIDS, lack glutathione in their body cells. Continuous use of skin bleaching pills with glutathione is said to be effective in gradual lightening of skin tone, as it inhibits melanin production. It is also claimed that most of these products offer permanent skin bleaching; as the whitening effect of glutathione is said to last forever, if you avoid exposure to sun and other harsh elements. As a skin whitening product, the reduced form of glutathione (L-glutathione) is used.
Usually, bleaching pills are recommended for those who are above the age of 18 years. The dosage is suggested on the basis of skin tone and body weight, in individual cases. Even the health condition of the person should be taken into account. While those with lighter skin need small doses, dark-skinned people may require large doses. In case of fair-skinned people, it may take a month of regular usage to achieve noticeable results. However, dark-skinned people may require 10 to 18 months of continuous use for improving their complexion. Some people suggest ingestion of vitamin C supplements with skin bleaching pills, so as to get best results.
While other skin whitening products act from the exterior, these pills work from the cells of the body. In fact, skin bleaching pills contain nothing other than glutathione, which is a tripeptide that is synthesized by some amino acids, inside the human body. These tiny glutathione molecules are found to be present in the body cells, in meager amounts; and play a very important role in maintaining health. It has an active part in metabolism, cell growth, immune response, protein synthesis, and regulating the events that take place inside the cells.
