“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 takesumi bright 3-step system is designed to minimize dark spot pigmentation and address extreme odor and excess sweat issues

the kojic acid bar
Brightens dark spot pigmentation on body & underarms with added odor protection

bright deodorant

niacinamide deodorant
Niacinamide & alpha arbutin brighten dark underarms, also neutralizes odor


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.

The best non-toxic deodorant I've ever used!

Honestly the beeeest non-tox deodorant - and I've tried MANY. Smells great, goes on smooth (even when you get to the bottom of the stick). No having to warm it up with your palm or any of that nonsense. I love the smell, it keeps me covered all day and is buildable. Not greasy or chalky and never stains my clothes. Honestly so impressed with this formula - my holy grail!

As described

Not only do you great deodorant but it also brightens knee caps, elbows and underarms!!

Well made

So far it glides on without any residue. It has no smell feels very good on my skin. It is still too early to talk about the brightening effects.

Love love love!

Love the texture, smell, and the lasting power of this deodorant. My all time fave! Still too recent to comment on the “brightening” effects, but it does a great job of keeping sweat and odor at bay

It works

This is the best natural deodorant that does what it said.
