Overview

• Researchers at Nanyang Technological University developed a transparent microgel from Camellia pollen using a water-based process that avoids harsh chemicals.
• In controlled tests, the formulation delivered roughly SPF 30 UV protection comparable to commercial sunscreens and reduced skin temperature by about 5°C for around 20 minutes.
• Coral exposure experiments found commercial sunscreen triggered bleaching within two days and death by day six, while the pollen-based version left corals healthy for up to 60 days.
• Animal studies by collaborators at Seoul National University indicated reduced UV-induced skin damage and inflammation, with Camellia outperforming sunflower pollen in comparisons.
• The team notes the results are from laboratory settings and plans to improve wear and water resistance, validate allergen safety, scale production, and conduct real‑world environmental testing before any product launch.
