Siberian fir oil and allantoin are included to support the skin's condition alongside the primary sensory effect. Siberian fir oil contributes a traditional, refreshing aromatic note that many find pleasant, and in body care contexts, oils like this are often chosen for their invigorating qualities when massaged into tired areas. Allantoin is a cosmetic ingredient recognized for its soothing and skin-softening properties, which can be beneficial if your skin feels dry or easily irritated from daily activities or environmental factors. These components, combined with glycerin for moisture retention, mean the gel aims to leave the application area feeling calmer and more comfortable, not just temporarily cool. They do not provide medical treatment, but work within the formula to make the product more than a simple cooling rub. As with any product containing essential oils, be mindful of potential individual sensitivity.
