Brightening effects are amplified when using the takesumi bright system, compared to a single product.

STEP 1: the kojic acid brightening bar
First, the brightening bar minimizes the appearance of dark spot pigmentation with kojic acid and licorice root extract, while also eliminating odor-causing bacteria in the underarms.

STEP 2: the niacinamide brightening deodorant
Next, this deodorant combines niacinamide and alpha arbutin to brighten underarms while a potent fermentation extract and activated charcoal helps control odor.

STEP 3: the sweat powder
Finally, the sweat powder absorbs excess moisture and creates a silky barrier on the skin to prevent chafing and friction that can contribute to hyperpigmentation and underarm rashes.

STEP 1: the kojic acid brightening bar
  • Use the kojic acid bar in the shower every morning before deodorant application.
  • To maximize the brightening and bacteria-eliminating power of this soap, lather the bar and then massage into the underarm area in circular motions using your fingers or a gentle exfoliating brush.
  • Leave the lather on the area for 30 seconds before rinsing off to give the formula time to absorb.

STEP 2: the brightening niacinamide deodorant Apply a generous layer of the takesumi bright niacinamide deodorant to underarms.

STEP 3: the sweat powder Apply a generous layer of the sweat powder over top of your deodorant for extra protection against excess perspiration.

“As someone with sensitive skin, I was nervous to try something new to help the pigmentation under my arms. I’ve been using this duo for almost 2 months now and I’ve noticed quite a difference!”


One month result

“[…] after over a month I can see the results […] So far, I’m satisified and I can’t wait for my underarm to lighten even more!”


The longer the pigmentation has been present, the longer it will take to see significant improvement. Customers have reported seeing initial results within the first couple weeks, with more significant results within 4-6 weeks. 

Use both steps (the kojic acid brightening bar and niacinamide brightening deodorant) for faster underarm brightening results

Post-inflammatory hyperpigmentation is a result of irritation. Brightening treatments will be unsuccessful until underlying cause of inflammation has been addressed. 

We recommend implementing the following tips: 

  • Shaving is the #1 cause due to irritation. Use a shave oil, shave at night and don’t apply anything to the area for 12-24 hours following shaving. 
  • Avoid irritating underarm products that contain ingredients such as baking soda, aluminum or high levels of fragrance 
  • Reduce chafing and friction in affected area, including chafing from tight, non-breathable clothing materials 

If your main concern is to treat dark underarms, then you should use the 2-step takesumi bright system for dark underarms. It will manage odor and dark underarms at the same time. 

If you are not concerned about dark underarms, then use the 2-step takesumi detox system for excess odor. 

No, the niacinamide brightening deodorant is not an antiperspirant. It is an aluminum-free natural deodorant and thus doesn’t stop you from sweating. It contains a potent fermentation extract and activated charcoal to neutralize odor and manage odor-causing bacteria. 

The kojic acid brightening bar can be safely used on dark spot pigmentation found on the: 

  • Underarms* 
  • Dark elbows & Knees 
  • Dark Inner Thighs 
  • Buttocks 
  • Hands (to address age/liver spots) 

It can also be used on dark spots and blemish marks left behind from: 

  • Ingrown Hairs 
  • Bacne (Back Acne) Scars 
  • Chest Acne Scars 
  • Buttocks Blemishes (buttne) 
  • Insect Bites 


For external use only. Do not use in the vaginal region or to shave underarms.Do not use after shaving. Always shave in the evening and allow your skin to calmbefore using thisproduct. 

For faster brightening results usethe takesumi bright system: 

STEP 1: the kojic acid brightening bar Moisten the bar andapply the lather to affected areas with a soft and gentle cloth or siliconeexfoliating brush (fingers can be used if exfoliating has occurred more thantwice 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 taketo see significant improvement.Post-inflammatory hyperpigmentation is a result of irritation. Brightening treatments will be unsuccessful until underlying cause of inflammation hasbeen addressed.

First Time

I have been searching for something to help with my dark underarms and I have tried so many thing and I bought this out of curiosity. It lightened my dark underarms, neck, inner thighs, and elbows. At first I didn’t notice a difference until I stopped using it and the darkness came back. I will for sure buy another and continue the routine.

I’m sold!

I’ve used one full brightening deodorant so far and just ordered my second. My under arms are definitely lighter and I will continue to use this product. I love that it’s both a deodorant and a skin brighter. It takes away the need for an extra step in my daily routine, which enables me to stay consistent with skin brightening.
