According to celebrity esthetician, Renee Rouleau, the following are key active ingredients to look for in any serum, regardless of the price.
Soluble Beta Glucans – for lessening breakouts from inside out
White or Red Tea – for providing anti-inflammatory relief
Glycolic Acid – for exfoliation
Magnesium Ascorbyl Phosphate ( Vitamin C ) – for fading brown spots
Anti-oxidants, such as vitamin E, for fighting off free radical damage
Peptides for skin firming.
“Any skin serum will do a great job at carrying active ingredients deep within the skin,” says Rouleau. “For daytime, use antioxidants and sunscreens as your skin is on the defense. At night, use repair ingredients like acids, enzymes and peptides.”
