These Plants Can Reduce Underarm Irritation Even in Hot Weather? Here's The Answer

In 2023, hot weather has affected almost all parts of the world, including the US and Mexico, Southern Europe, and China. The highest temperatures were even felt in Northwest China and Death Valley in the US, reaching 50 degrees Celsius on July 16, 2023. Indonesia also experienced similar conditions. Ana Oktavia Setiowati, the Coordinator for Weather Information Services at BMKG, emphasized that climatologically, temperatures ranged around 34-36 degrees Celsius in April, May, and June 2023.

The intense heat, combined with regular activities in air-conditioned rooms, can potentially trigger illnesses. Referring to, transitioning from cold to hot temperatures could potentially cause diseases such as joint pain, asthma, allergies, or migraines. Observing this, some people began to take care of their health by consuming vitamins and exercising.

Surprisingly, extreme weather conditions like this haven't reduced people's interest in exercising. Various outdoor activities directly exposed to the sun, such as jogging and cycling, are being carried out by many individuals. Moreover, Statista notes that running is among the most popular and widely practiced sports globally. In the United States alone, nearly 50 million people engaged in running and jogging in 2021. Furthermore, walking for fitness attracted over 110 million participants in the U.S. during the same year.

Meanwhile, the interest in cycling is also quite high, especially when considering a journal titled "Sports Bicycle Market Analysis North America, Europe, APAC, Middle East, and Africa, South America - US, Canada, China, Germany, UK." It's explained that the sports bicycle market size is estimated to grow at a CAGR of 6.19% between 2022 and 2027. The market size is forecasted to increase by USD 5.52 billion.


High-intensity exercise along with hot weather can potentially have a significant impact on health, particularly on the skin.

The hot weather can lead to skin irritations, especially in sensitive areas or where skin rubs together, such as the underarms. Reddened skin can appear due to itching and inflammation, which might be so intense that scratching becomes uncontrollable. This can disrupt appearance and lead to a lack of confidence.

Using ingredients like Dermasooth™ is a solution. Dermasooth™ is a blend of actives derived from Enteromorpha compressa, a seaweed rich in marine pentasaccharides. Dermasooth™ also includes Tulsi, a sacred plant in India, known for its calming properties and richness in ursolic acid, which acts as a free radical scavenger. Lastly, Lady’s Thistle exhibits antioxidant activity.

Research has been conducted with a sample of 25 Caucasian women with fair and sensitive skin, prone to irritation after shaving. They applied a lotion with Dermasooth™ on one underarm and a placebo on the other for 15 days. The results showed that as the barrier function of the skin is strengthened, the skin is more protected and less susceptible to inflammatory processes.
