Cysteamine Whitening Cream – Prices/Cost, Reviews, FAQs


What Is The Cysteamine Whitening Cream?

The cysteamine whitening cream uses the active ingredient cysteamine, the simplest natural aminothiol produced in human cells – a metabolite of amino acid L-cysteine.

Cysteamine promotes the transport of L-cysteine into human cells. This can be further used to synthesise Glutathione, an antioxidant. Cysteamine inhibits melanin (dark pigment) synthesis in skin cells, therefore reducing pigmentation.

Is The Cysteamine Whitening Cream New?

Initially, oral Cysteamine was approved by the U.S. Food and Drug Administration for human use for cystinosis, a rare genetic disorder. However, research has found that Cysteamine has significant de-pigmenting activity such as in melasma.

But despite this, it has never been formulated into a cream due to its unpleasant sulphur odour. Efforts have enabled a stabilised form of a cysteamine whitening cream with reduced odour.

Which Pigmentary Disorders Has The Cysteamine Whitening Cream Been Shown To Be Effective?

The cysteamine whitening cream has been shown to be effective for:

  • Melasma, particularly epidermal melasma
  • Lentigines (sun spots)
  • Post-inflammatory hyperpigmentation
  • Becker’s Nevus
  • Lighten skin colour overall

How Should The Cysteamine Whitening Cream Be Used?

Cysteamine Cream can be applied any time of the year regardless of sun exposure and is suitable for all skin tones.

The cream is applied to the desired areas with pigmentation once daily and is washed off after 15 minutes using mild soap and water. After drying the skin, a moisturizer is applied.

  • Cysteamine Cream should be applied once a day on rested, calm skin (evening or morning before a shower) to reduce skin irritation
  • Exposure time can be gradually increased after 6 weeks if there are no signs of skin irritation such as redness or dryness
  • Sunscreen should still be continued daily
  • To maintain its effects, cysteamine cream should be continued at least twice a week indefinitely

A reduction in pigmentation is seen after 6 weeks. Optimal results are seen after 8 – 12 weeks.

As Cysteamine is naturally occurring in human cells, it is  generally a safe medication for most people. It may cause temporary burning sensation or redness that goes away within 30 minutes.

More persistent skin irritation should be treated with moisturisers. To date, no serious adverse side effects have been reported with Cysteamine use.

Cysteamine Cream should not be used in those with a personal or family history of Vitiligo, a depigmenting skin disorder. It should also not be used by pregnant or breastfeeding women, as no study has been performed during pregnancy or breastfeeding.

The cysteamine whitening cream can be used in conjunction with other de-pigmentation treatments such as our Anti-Pigmentation Laser, Pico Laser, and Clear + Brilliant Laser.
