AI Technical Summary

Technical Problem

Existing technologies lack specialized formulations for rapid relief of itching, allergy, and skin barrier repair in response to delayed-onset allergic reactions caused by midge bites, and conventional drugs suffer from slow onset of action or significant side effects.

Method used

Using specific proportions of ingredients such as loratadine hydrochloride, calamine, menthol, camphor, ceramide, and panthenol, a cream or ointment is prepared through an emulsification process. Combined with pH adjustment, it forms a mild and low-irritant topical medication that targets and blocks histamine receptors, quickly relieving itching and repairing the skin barrier.

Benefits of technology

It provides rapid relief of delayed-onset allergies after midge bites, with an anti-itch efficacy rate of over 95%. It takes effect in 10-15 minutes and lasts for 6-8 hours. It is suitable for children, pregnant women, and those with sensitive skin, and has no obvious side effects.
