Secret is the first brand of antiperspirant for women in history, launched in 1956 by Procter & Gamble after a decade of research and development. Secret is mainly sold in North America, and has won the "Readers' Choice Award" selected by Allure, an authoritative beauty magazine, and has a high market share and brand recognition in North America for a long time, but there is no formal sales channel in China for the time being.
 
Secret's antiperspirants are divided into five lines: Clinical Strength, Original, Outlast Xtend, Active and Fresh. The Pharmaceutical Strength series has been recommended by many sweaty customers and doctors for its mild and efficient performance, while other daily series have taken advantage of the sales advantage due to their balanced and comfortable use and high cost performance.
 
The products are available in a variety of textures, including solids, gels, roll-ons, aerosols, etc., among which stick solids, especially invisible solids, are the most popular. The active ingredient of other dosage forms other than aerosol is glycinate chlorohydroxyaluminum zirconium, and the whole line of products is pH balanced, mild and skin-friendly.
 
The Pharmaceutical Strength Series is the No. 1 selling pharmaceutical-grade antiperspirant in North America. With an active ingredient concentration of 20%, it has the best perspirant suppression among all series, and the effect can last for 48 hours, making it suitable for daily use by people with excessive sweating and body odor. The antiperspirant strength of the long-lasting series, sports series and refreshing series is not as strong as that of the medical strength series, but the deodorization effect can also be maintained for about 48 hours.
 
The Sport collection features a sporty fragrance that effectively removes odors and releases aromas. Generally speaking, aerosols feel the driest on the skin and are less effective than solids and liquids, but the Secret Sports range has a strong antiperspirant mist effect and can meet the needs of sweat suppression during exercise. The long-lasting fragrance is pure and clean, and the performance is similar to that of the sports series. The refreshing series has a rich and unique floral and fruity scent, which is not lacking in activity and fun.
 
The classic series is the series with the weakest antiperspirant and deodorant effect, and needs to be applied daily, but it is effective enough for people with ordinary sweat levels, and there are many fragrance types to choose from, and it is the most cost-effective daily antiperspirant in secret. For sensitive skin, the Medicinal Strength, Long-Lasting and Classic ranges are available in fragrance-free versions.
 
For people who sweat a lot, there is one thing to note: Secret products generally have a strong antiperspirant ability, compared with other series, the concentration of active ingredients is not much different, but the price is almost twice as high. At present, the purchasing price of the pharmaceutical strength series is about 70 yuan, and the other daily models are mostly between 30-50 yuan.
