What should I do? Our product has a special formula with Ceramide Capsules.

Is it okay to use this product in the morning and evening? Product is suitable for both morning and evening use. Regardless of the ingredients, it is recommended to use with sunscreen during the day for skin protection. Should I apply sunscreen when going outside? While the product does not contain photosensitive ingredients, it is recommended to use sunscreen when going outside to ensure stable effect and skin health. Is it okay to use the serum when the color changes over time? The color change is due to the natural color of the ingredients, not artificial dyes. Long exposure to light may cause the color to fade, but the product remains effective. Is the serum's color artificial, if so, will it stain the skin? The color comes from natural ingredients (Indian Lotus Flower Extract & Ivy Gourd Fruit Extract), not artificial dyes, so it will not stain the skin.
