There are a wide variety of factors involved in the skin aging process: exposure to the sun without sun protection, lack of hydration through the use of facial creams and poor diet are some of the factors that we can modify to protect the skin and slow down the appearance of signs of aging such as spots, expression lines and wrinkles. What are the most harmful foods for the skin? Sugar Excessive consumption of sugars can accelerate skin aging as it favors the breakdown of collagen and elastin fibers. It also directly affects the blood vessels, reducing the skin’s elasticity.

Honey, coconut sugar and natural stevia are some healthy alternatives to replace it.


When ingested in excess, salt can cause a rapid increase in blood pressure, leading to a reduction in collagen production and premature aging of the skin. In addition to consuming it in moderation, we can replace it with sea salt or spices.


This popular infusion is characterized by its dehydrating effect. Excessive consumption can directly affect skin tone and hydration. For this reason, its moderate intake is recommended or its replacement by other infusions such as green tea or fruit juices, which are also rich in antioxidants that prevent premature aging.


In addition to the already known detrimental health effects of excessive alcohol consumption, alcohol causes severe dehydration that dries out the skin and favors the appearance of open pores, wrinkles and skin blemishes.

Red meat

Experts recommend a moderate consumption of up to 2 servings per week. Red meat is rich in carnitine, a substance that in excess causes a hardening of the capillaries and as a consequence affects premature aging. It can be replaced by other protein-rich sources such as eggs, legumes or oily fish.
