FAQ
our most common questions, answered with science-backed clarity and care.
Does it really reduce puffiness instantly?
Yes. The clinically optimized cooling head reaches skin temperatures as low as ~10°C within seconds, effectively reducing under-eye puffiness and swelling for a refreshed look in just 3 minutes.
Do I need to store it in the fridge?
No refrigeration needed. TempFusion™ technology maintains cold and heat levels on its own, anytime, anywhere.
Is it safe for sensitive skin?
Absolutely. It uses medical-grade metal for safe, gentle contact with all skin types, including sensitive skin.
How long does the battery last?
A full charge provides up to 60 minutes of continuous use, enough for weeks of daily treatments.
Can I use it with my serums or creams?
Yes. Using heat therapy before applying skincare enhances absorption, while cold therapy helps lock in active ingredients.
How often should I use it?
We recommend daily use for optimal results — mornings to reduce puffiness, evenings to promote absorption and relaxation.
How is this better than an ice roller?
Unlike ice rollers, TempFusion™ maintains a consistent temperature without warming up or needing a freezer, and combines hot, cold, and massage therapies in one device.
Does it help with dark circles?
Yes, the SOTHERA Glow Pen can help reduce the appearance of dark circles. The cold therapy mode specifically targets the under-eye area, reducing puffiness and constricting blood vessels, which can help minimize the appearance of dark circles. Additionally, the heat massage mode encourages better circulation, promoting lymphatic drainage and improving skin tone and texture around the eyes.
For best results, it’s recommended to use the cold therapy mode in the morning to de-puff and refresh the under-eye area, followed by heat therapy to enhance serum absorption if you’re using any eye creams or serums.
