"I have been using this once a day in the morning for about a week. No irritation even though I have dry reactive skin so I will continue to use it. Hopefully I will see results with this first bottle."
"Honestly I loved this stuff. It did wonders for my skin. Unfortunately though with time it started irritating my skin. It started making my skin itchy and red. I even stopped using it as much but it still continued to do it. Nothing against the product my skin just didn't agree with it."
"I’ve always been sensitive to vitamin C but this one not only didn’t break me out but gave me results fairly quickly. My skin is brighter and radiant and my dark spots are starting to fade. Will continue to purchase and highly recommend."
"I have sensitive mature skin , this doesn’t dry or irritate my skin. I have tried several other products, but this is the only one I see results and my skin looks moisturized , soft and glowing. I very rarely wear makeup. Love Tatcha products."
"I have used multiple serums over time but I loved this one. It shows visible difference in a week. I loved it!"
"I think it is decreasing the darkness of my facial spots, but it could be wishful thinking too. I believe the spots are getting lighter. ☺️ I will continue on with it and buy the full size."
"One of my favorite Tatcha products. This product layers well with the other serums and the moisturizer."
"This Tyrone inhibitor is powerful as a base under my sunblock during the summer. At night, I used it during the winter and saw it continued writing of the skin. Highly recommend!"
"Maybe I have not been using it long enough but it hadn’t done anything for my aging face"
"I was using another brand of brightening serum and decided to try Tatcha's serum because I love their products. I really don't like the stickiness it leaves, and I cannot stand the smell!! To me it smells like burning wood or bacon (which I don't eat). I think it is too late to return because I bought it with a bunch of products months ago, but I just opened it last night."
Frequently asked questions

Sunscreen protects the skin from UV rays, but it is proven to also protect the skin barrier by shielding it from free radicals and preventing dehydration (from repeated sun exposure). However, some modern sunscreen formulas include additional ingredients that can actually repair and strengthen the skin barrier while also shielding from UVA and UVB rays. Look for ingredients that tout their reparative nature, like ectoin, alongside SPF 30+ formulas, to ensure skin is protected while it repairs.

Many moisturizers hydrate, but the right formula can also impart a dewy glow. These options actually work to get the skin naturally glowing over time, which is exactly what Tatcha’s dewy moisturizers accomplish. These formulas are powered by Hadasei-3, a potent and proprietary complex formulated to hydrate, gently resurface, and even make the products applied afterwards work better. Tatcha has many moisturizers, but two specific formulas that embrace dewiness: The Dewy Skin Cream and The Dewy Milk Moisturizer.

The Japanese game of fukubiki is a centuries-old tradition still practiced today at seasonal festivals and even retailers. Learn about the custom and how you can win up to 4 complimentary minis for a limited time. What’s your favorite summer activity? If you have the chance to visit Japan, you’ll likely get to experience one of its famous summer festivals, or natsu matsuri. Though each has its own meaning and purpose, at their root most seasonal festivals are held to honor nature’s gifts, reconnect with the community, and pray for good fortune. These vibrant and colorful celebrations are often a showcase of the neighborhood with local craft vendors, dancing, fireworks, carnival games, and even a lottery known as fukubiki. The traditional game is said to have originated in 702 when Emperor Shomu held a New Year’s party where strips of paper were drawn for prizes like a beautiful cloth. Modern versions are sure-win raffles that can be held anytime of year where paper fukubiki are drawn from a wooden box. Fukubiki are said to reveal one’s fortune, and in more recent years, earn you a prize at your favorite retailer from mystery bags to discounts. To bring the spirit of good fortune to you, we’ve started our own fukubiki-inspired tradition. From July 30th to August 9th, everyone will be a winner with a choice of up to four complimentary minis with a $100+ order. You may even win the chance to choose a full-size prize!
