1. Genetics - If mouth lines run in the family then genes might be the cause. There is only so much you can do about genes. Unfortunately you can't choose what you inherit and what you don't inherent from your family.
2. Repeated over exposure to the sun - The sun's uv rays are one of the most common causes of aging in skin. Since the aging of facial skin can result in mouth lines, then avoiding unnecessary direct contact with sunlight can help prevent the formation of lines around your mouth.
3. Facial expressions - Repeated facial expression can result in the formation of facial lines. Especially if you have thin aging skin.
4. Poor diet - A diet that is rich in veggies and fruits can really help tighten your skin. This is because fruits and veggies are rich in antioxidants which help fight aging free radicals.
5. Low quality face cream - A large majority of the skin creams we use today contain skin aging synthetic ingredients. For example, mineral oil is a very common ingredient in facial moisturizers despite the fact that it causes premature aging.
To get younger looking facial skin, rather use a product which contains natural anti aging ingredients like Natural vitamin E, Cynergy tk, Avocado oil and active manuka honey.
