Smoking
Many diseases are associated with smoking, but many are likely unaware that smoking contributes to cellulite formation. A Time article lists smoking as one of the possible causes of cellulite. Some may dismiss this as a myth, but it would be wise to avoid or stop smoking given that it also comes with more serious health risks such as lung cancer, chronic obstructive pulmonary disease, stroke, heart disease, emphysema, and chronic bronchitis.
Cigarette or tobacco smoke is known to have the effect of reducing blood flow in the skin as well as weakening and disrupting collagen development. These unwanted consequences of smoking damage the connective tissues underneath the skin, making it easy for fat buildup to become more visible and form unsightly bumps on the skin. The nicotine content of tobacco or cigarettes also affects skin moisture and elasticity as it narrows down blood vessels and causes overall blood circulation impairment.
Moreover, smoking promotes the production of angiotensin-converting enzymes linked to inflammation and oxidative stress. As a result, it raises lipid peroxidation, which increases the likelihood of developing skin diseases.
