Caffeine in cosmetics works mainly as a vasoconstrictor. It narrows small blood vessels and reduces capillary permeability. Due to this, swelling under the eyes and dark circles can become less pronounced. It is worth understanding that the effect of caffeine on the skin appears quite quickly after application. But its disadvantage is that it lasts for a limited time after using the product. And also - the cumulative effect has not been confirmed.

Effect of caffeine

When applied, caffeine in cosmetics constricts blood vessels and limits the outflow of fluid into the tissues. Caffeine is most appreciated precisely for its effect on puffiness.

The effect of caffeine on the skin is a reduction in the visibility of puffiness. Most often it manifests itself through a fresher appearance of the area around the eyes:

  • reduces the severity of dark circles;
  • helps with puffiness after lack of sleep.

The best result is obtained with regular use. Then the skin looks more stable and rested.

Contraindications to caffeine

At concentrations of 0.5-5%, caffeine is considered safe for most people. But there are cases when it is better to refuse or be careful. These include:

  • allergy to caffeine or stimulants;
  • severe irritation or very dry skin.

Be sure to do a test on a small area of ​​skin. Then caffeine in cosmetics will bring benefits, not unpleasant sensations or results.
