For faster brightening results use the takesumi bright system:    STEP 1: the kojic acid brightening bar Moisten the bar and apply the lather to affected areas with a soft and gentle cloth or silicone exfoliating brush (fingers can be used if exfoliating has occurred more than twice a week). Massage for 30 seconds to allow the actives to penetrate the area before rinsing off.    STEP 2: niacinamide deodorant Follow with a generous application of deodorant to clean, dry underarms daily.    STEP 3: the sweat powder For extra protection against excess perspiration, and to prevent chafing and irritation that can lead to hyperpigmentation, apply a generous layer of the sweat powder over top of your deodorant.    The niacinamide deodorant can also be used following the kojic acid brightening bar on areas with dark spot pigmentation and experience chafing and friction such as the inner thighs.
Once dark spots are minimized, continue to use the deodorant on underarms for lasting results.
Do not use after shaving or waxing. Always shave at night and allow the skin to calm down before applying the deodorant.
Some may notice slight redness or discomfort after using the deodorant for the first time. In order to ensure you can use the formula, test the deodorant on your forearm for twenty-four hours before applying it on your underarms and body. Look out for any unusual reactions.
Note: The longer the pigmentation has been present the longer it will take to see significant improvement. Post-inflammatory hyperpigmentation is a result of irritation. Brightening treatments will be unsuccessful until underlying cause of inflammation has been addressed.
