The following are some of the major reasons the skin becomes darker during a lightening treatment: The first reason and probably the most important is using your lightening products during the day alone. When using lightening products in the morning it can make the skin very sensitive to sunlight, resulting in the skin becoming darker overtime. This is the main reason skin lightening products are recommended to be used twice a day (morning and night) except where otherwise directed. At night, the skin is less sensitive due to the absence of the sun thereby allowing the skin lightening products to be more effective. Q7Paris offers a separate Day and Night lightening lotions. Check them out here. Not wearing sunscreen every morning is another big culprit. Using lightening products, especially during the day in hot climatic conditions makes the skin very sensitive to sunlight. Wearing sunscreen every morning will help ensure more dark spots do not occur thereby leaving your complexion more luminous. Over-exfoliating the skin is another factor. Too much exfoliation can dry and irritate the skin; consequently, resulting in inflammation which often bring about darker skin tone. Exfoliate with care. Don’t over-do it!
