Parëva Beauty C35.5™ Firming Glow Serum ($74)

According to the brand, the first-to-market formula targets firmness, discoloration and premature aging at the cellular level with 30 percent tetrahexyldecyl (THD) ascorbate—a more stable, oil-soluble and skin-compatible form of vitamin C—along with ceramides, antioxidants and the brand’s longevity complex, Molecur 3. (In short, the formula penetrates deeply with less potential for irritation.)
