There are some general characteristics that are often associated with Japanese Korean, Caucasian skin types, as compared to skin from  humid/hotter climates such as Singapore / Malaysia / Thailand /  Indonesia.

1. Japanese and Korean skin: Japanese and Korean skin types are often described as having a tendency towards dryness and sensitivity. This may be due in part to their climate, as both countries have relatively low humidity levels. 

2. Singaporean / Malaysian / Thai /  Indonesian skin types: Such skin types are often described as having a tendency towards oiliness and acne, which may be due in part to their hot and humid climate. As a result, skincare routines in these countries often focus on controlling excess oil production, skin whitening, pore size control, preventing breakouts, and protecting the skin from UV radiation.

3. Sebum production: Asians tend to have a higher level of sebum production, which can make their skin more prone to oiliness and acne. Caucasians, on the other hand, tend to have lower sebum production and may be more prone to dry skin.

4. Aging: Studies have shown that Asians tend to have thicker and more resilient skin than Caucasians, which can make them less prone to wrinkles and fine lines. However, Asians may also experience hyperpigmentation and other skin discoloration issues more frequently than Caucasians. Asians may also experience more volume loss and sagging in the cheeks as they age.

5. Pigmentation: One of the most noticeable differences between Caucasian and Asian skin is pigmentation. Caucasians tend to have less melanin, the pigment that gives skin its color, compared to Asians. As a result, Caucasians are more prone to sunburn and sun damage, while Asians are more prone to hyperpigmentation, which is an excess of melanin that can cause dark spots or uneven skin tone.

6. Aging: There are also some differences in the way that skin ages between Caucasians and Asians. Caucasians tend to show signs of aging earlier, such as fine lines and wrinkles.

It's important to note that these are generalizations, and individual skin types can vary greatly within each population. Additionally, many people may experience a combination of different skin concerns, such as dryness and acne, or sensitivity and oiliness.

It's important to choose skincare products and routines that work best for your unique skin concerns and needs, rather than simply following trends or cultural preferences.
