Examples
Embodiment 1
[0017] Example 1: Sunscreen lotion containing marine algae (laver) extract--tribyl amino acids (Mycosporine-like amino acids: MAAs):
[0018] Weigh 10 grams of laver, grind and crush it, add 1000 ml of 90% methanol, and extract at 37°C for 5 hours. Methanol was recovered at 65°C by a negative pressure distillation device, and the remaining liquid was naturally air-dried to obtain the natural ultraviolet absorber of laver.

Embodiment 2
[0024] Example 2: Sunscreen lotion containing marine algae (red cabbage) extract--trimazole amino acids (Mycosporine-like amino acids: MAAs):
[0025] Weigh 10 grams of red cabbage, grind and crush it, add 1000 ml of 80% methanol, and extract at 4°C for 12 hours. Methanol was recovered at 65°C by a negative pressure distillation device, and the remaining liquid was naturally air-dried to obtain the natural ultraviolet absorber of laver.

Embodiment 3
[0031] Example 3: Sunscreen lotion containing trityl imidazole amino acids (Mycosporine-like amino acids: MAAs):
[0032] Weigh 10 grams of red cabbage, grind and crush, add 1000 ml of 80% methanol, and extract at 50° C. for 2 hours. Methanol was recovered at 65°C by a negative pressure distillation device, and the remaining liquid was naturally air-dried to obtain the natural ultraviolet absorber of laver.
[0033] Components:
[0034] Production method: mix the liquid and add the solid, stir evenly, place for 1-2 weeks, then freeze at 0°C for 24 hours, filter the sample to obtain the finished product.
