Mustard oil itself doesn’t inherently darken the skin, but there are a few considerations that might help explain what you’re experiencing. Often, the perception of skin darkening could be linked to mustard oil’s nature to increase skin’s sensitivity to sunlight. This can lead to a higher tendency for tanning if one is exposed to the sun after application. Also, mustard oil can sometimes cause minor heat or irritation in some individuals, especially those with pitta imbalance. Such reactions might possibly give the appearance of darkening or contrast to your usual complexion.
Your concern about oily patches is something to consider too. For some people, especially those with kapha constitution, mustard oil might be bit heavy, potentially clogging pores and resulting in uneven skin tone. Mixing astringent substances like turmeric or sandalwood paste with the oil might balance this effect, cooling the skin and improving your experience.
To avoid further darkening, consider applying a lighter oil such as coconut oil or test kukui nut oil, which suits many skin types and doesn’t accentuate photosensitivity. It might be good idea to use the oil in the evening, let it stay for 20-30 minutes, and then rinse it off. Regular, gentle exfoliation, using ground chickpea flour or powder moong dal can also help keep the skin looking brighter.
If after these adjustments the darkening persists, or if there’s discomfort, it may be advisable to pause mustard oil usage and observe any changes. Also, consider getting your skin condition checked by a professional, as there might be other factors influencing this change. Protect your skin from direct sun exposure right after applying oils, as a general measure to reduce unintended effects.
