2026 Update: What the data says
In summary: Traditional uses are interesting, but they do not in themselves constitute clinical proof. The work available on various indigo extracts is primarily conducted on cells or animals (preclinical study on an indigo extract (2022), animal study on the application of an indigo extract (2022)). These do not demonstrate that a cosmetic Nila powder lightens human skin over the long term, nor that it works in three days. The most reasonable benefit remains that of a cosmetic ritual: cleansing, very gentle exfoliation, and a temporary improvement in the skin's appearance.
In accordance with European criteria, a cosmetic claim must be honest, understandable, and supported by verifiable evidence (European Regulation 655/2013 on cosmetic claims). This article therefore promises no bleaching, no healing, and no immediate results.
Precautionary advice
- Perform a patch test on a small area for 24 to 48 hours.
- Avoid the eyes, mucous membranes, and irritated or broken skin.
- Start with short and infrequent usage.
- Discontinue use in the event of persistent redness, burning, or itching.
- Seek advice from a healthcare professional in case of skin disease.
My experience with Nile blue:
After browsing numerous websites on the Internet, I learned that the use of blue indigo for the skin is part of ancient Moroccan rituals, particularly for those living in the desert. They massage the bride's body skin with it for 3 days before the wedding date so that her skin becomes brighter and fresher.
Because I have dark areas on my body, I decided to test the effectiveness of Blue Indigo for skin lightening. I looked for a recipe for which I could easily find ingredients, so I chose this recipe, which consists of:
- 4 teaspoons of Moroccan indigo powder.
- A few drops of argan oil.
- A container of yogurt.
How to use Nila blue indigo with argan oil:
- I mixed the Moroccan indigo with argan oil and yogurt.
- I spread the mixture with a mask brush over the dark areas I wanted to lighten; I even spread it on my face, but I avoided the area around my mouth and eyes.
- I left the mixture on for 30 minutes, then washed my skin with lukewarm water.
- Afterward, I applied the moisturizer I usually use.
- I continued to follow this blue indigo recipe for 4 consecutive weeks, and my face and body really seemed lighter, fresher, and more radiant.
- I won't hide from you that I was a little apprehensive at first because my skin had taken on a slight blue tint, but its effect soon faded.
