Brandefy compared the Truth Serum Collagen Booster to the Bright Idea Vitamin C + Tri-Peptide Collagen Protecting & Brightening Serum. Here's what they had to say:
Olehenriksen is $74 for 1.7 oz and Bliss is $24 for 1.7 oz. Both contain forms of Vitamin C (to brighten) as well as Vitamin E (to soothe). Bliss contains a blend of peptides that help with anti-aging. Olehenriksen lacks this peptide blend. Testers enjoyed the Bliss serum immensely. They thought that while it looked more like a moisturizer and less like a serum at first pump, it rubbed in like a serum and took on more of an oily consistency during absorption. Olehenriksen is an oily serum throughout. Both brands smell like oranges, but Olehenriksen has a stronger citrus smell than Bliss. Testers would switch to Bliss to save!
