On average, one can start to see results after 1-3 boxes of glutathione. However, this may vary per individual. Some may already see results in as early as 4 vials, while some with slow metabolism may take 2 boxes or more to see the effect.
Generally, you will start to see results within the following period:
- Fair to Light Brown skin tone: 1-3 months
- Medium to Dark Brown skin tone: 3-6 months
- Dark skin tone: 6 months or longer
Whitening effects will vary with skin types and your lifestyle. Faster results are seen if you limit your alcohol intake, caffeine intake, smoking, and other forms of vices that might lessen the anti-oxidant effect of your glutathione and vitamin C.
Lastly, avoid too much exposure from sunlight, as it slows the whitening process due to the formation of melanin. Make sure to wear sunscreen with at least SPF 40 protection.
