There may be the following reasons for this phenomenon:

1. Environment

There is such a phenomenon: 

The face is easy to dry and chapped in winter, but not in summer. Many people wonder why? why?

Obviously, it has something to do with the dryness of the weather. The air is generally not dry in summer. Plus the skin is prone to sweating. Therefore, the outermost skin of the skin will not be dry, chapped, rough and peeling will not occur.

In winter it's the opposite. The skin doesn't sweat much. Second, the air is relatively dry, and the water loss from the outer layer of the skin is intensified. The skin is prone to dryness, tightness, peeling, or even chapped

2. Hormones

The second reason you may not have thought. The skin suddenly becomes smooth and then rough, which may be related to hormonal fluctuations in the body! For women of childbearing age.

The 3 major hormones in the body fluctuate wildly every month. Estrogen, progesterone, androgen. Generally speaking, when estrogen is elevated, the skin is in better condition (smoother). So some people feel the cyclical changes in the state of the skin

extreme performance is. Some people are prone to acne breakouts before their period

3. Skincare Product

The last reason you may never think of the products you use!

Some ingredients will soften the skin (like exfoliating ingredients)

But the ingredients that make the skin rough and dry may appear to be absent on the surface, but it may happen when you actually use it

Such as the following categories

1) Exfoliating ingredients

Although the skin becomes soft and smooth at the beginning after the skin becomes thinner, the water-locking ability becomes poor, and the skin may become dry and rough.

2) Certain ester components (oils)

Although it will be absorbed into the superficial layer of the skin at the beginning of use, making the skin soft and smooth, but after a period of time, it may cause problems in the differentiation of skin cells, and it is easy to cause dry skin.

This is how cheilitis develops in some people.

3) Makeup remover ingredients

Generally speaking, the skin will appear smoother after removing makeup.

However, after frequent makeup removal, the skin becomes thinner, the ability to lock water becomes poor, and then the skin is prone to dryness and roughness.

4. Summary

Okay, let's make a summary of today's content: 

Some people have a roller coaster-like change in their skin condition. Sometimes fine and smooth, sometimes rough and dry

This is due to a number of possible causes: changes in ambient humidity, certain products used, makeup removal (over-cleaning), etc. And it's easy to avoid this

Choose products with high safety, reduce makeup and remove makeup, and do basic moisturizing.

That is to say, excessive skincare can cause skin problems.
