I want to get rid of my inner dryness before autumn comes. Would Celle Diem be effective?

In the summer, the skin is dry due to the air conditioner, and

My skin is so severely dry from the inside during autumn and winter due to the weather that it becomes dry.

My skin is on the thinner side, so I tend to have a lot of fine wrinkles.

It appears especially often around the corners of my mouth.

Moreover, I neglected my skincare during the heatwave week this summer

Not only has my skin texture become rough, but it is also very itchy and feels dry and rough.

These days, even if I just apply sunscreen with good coverage, I can feel my skin rejecting it..

It seems like skin itching calms down for about an hour after washing my face and applying a moisturizer to help it absorb.

Since then, I feel dryness again and the itching has gotten worse.

It seems like my skin barrier itself is compromised, so no amount of skincare is helping to improve it.

I'm wondering if Celle Diem can resolve severe inner dryness and get rid of the rough, dry feeling.

I looked up reviews for Celle Diem and saw that many people say it is effective even though it is expensive.

Celle Diem simply replenishes moisture to the skin or

I heard that it is a method of directly injecting a collagen-like substance rather than helping the body produce collagen on its own.

If you directly inject the ingredients lacking in your skin with Celle Diem

Will it definitely fix inner dryness and increase skin density?
