The choice of body lotion will vary depending on individual skin type and needs. However, both the large white and blue bottles of Dr. Morita have their own characteristics, depending on the options you provide.

1. Dr. Morita Cosmetics Big White Bottle: This body lotion contains arbutin, hyaluronic acid, vitamin C and other ingredients, which can brighten skin tone, moisturize and antioxidant. If you have oily skin or are looking for refreshing hydration during the summer, this large white bottle might be a good choice.

2. Dr. Morita Cosmetics Big Blue Bottle: This body lotion emphasizes deep moisturizing and contains collagen, hyaluronic acid and other ingredients, which can improve dry and rough skin. If you have dry skin, or need a more nourishing moisturizer during the winter months, the Big Blue Bottle may be more suitable for your needs.

In general, for winter use, the big blue bottle of Dr. Morita Cosmetics may be more suitable because it emphasizes deep moisturizing and can help improve the problem of dry skin. However, be sure to perform a skin test before using any new skin care product to avoid allergies or other adverse reactions. At the same time, you can also try other brands and types of body lotions depending on your personal skin condition and needs.
