Wrinkles — Conditions

What is Wrinkles?

Skin changes from aging as collagen and elasticity decrease

UV exposure, repeated facial expressions, and dryness are major causes, typically appearing first around eyes, forehead, and mouth.

Main causes & characteristics

Wrinkles are a change that develops as dermal collagen and elastin decrease and regenerate more slowly with age, weakening the skin's support and elasticity. UV-driven photoaging is known to accelerate aging by activating enzymes that break down dermal fibers, and repeated facial expressions, dryness, and smoking also play a role. They tend to appear first in areas that move a lot and have thin skin, such as around the eyes, the forehead, the glabella, and the mouth.

How to manage

Consistent daily sun protection is recommended as the basis for managing the pace of photoaging, and retinol, peptides, vitamin C, and adequate moisturizing are known to help with elasticity and texture care. It is generally recommended to start retinol at a low concentration 2–3 times a week to build tolerance and to use sunscreen the following day. If you want to improve deep wrinkles, you can explore options through a consultation with a dermatologist.

Good to know alongside

Collagen, photoaging, retinoids, and the difference between expression wrinkles and elasticity wrinkles are often mentioned together. Fine dryness lines and deep wrinkles may call for different care approaches.

Everyday care tips

Changing a sleep posture where you bury your face in the pillow and reducing the habit of squinting can help with expression-wrinkle care. Keep skin well moisturized.
