The Best Brightening Serums for Radiant-Looking Skin

If you’re struggling with dry and dull skin, a brightening serum might just be the Holy Grail you’ve been looking for. Working to improve skin’s radiance and even out tone, serums can make flat, lackluster complexions look plump and bright in just a couple of weeks. Keep reading to discover exactly what dull skin is and discover the best brightening serums for radiant, healthy-looking skin. 

What is dull skin? 

Lackluster and flat, dull skin often looks tired and gray and can feel rough and uneven to the touch.  

Why does my skin look dull? 

  • Slow skin cell renewal: With age, the natural skin cell renewal process slows, causing dead cells to accumulate on the skin’s surface. This layer prevents the skin from reflecting light and creating a healthy glow. Instead, skin looks tired and dull.  
  • Environmental stressors: Environmental aggressors can stimulate an overproduction of melanin (the pigment that gives skin its color), causing hyperpigmentation and dark spots to appear, leaving skin looking uneven. 
  • Dryness: While moisturized skin looks plump and healthy, dry and dehydrated skin often appears dull, flat and lackluster. 
  • Lifestyle: Poor diet, lack of sleep, lack of exercise, and stress can all affect the health and brightness of skin.
