For example if we have x=953, I want to select specifically the first digit (or the last two) and save it in another variable, so the outcome would be y=9 (or y=53)
Hydroquinone has also been linked to a medical condition in humans called ochronosis. This condition has actually been found in humans, not rodents, but the evidence is inconclusive at the moment. Ochronosis is a condition where the affected skin darkens in color, and also becomes thicker in texture.
Seven years later, thereâs still no verdict on whether or not hydroquinone is truly safe for humans to use. In the meantime, the ingredient can still be used in skin lightening products and is easily accessible over-the-counter.
