The Ordinary Hyaluronic Acid 2% + B5 (Original)

The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation):

What It Is

A hydrating, multi-molecular-weight hyaluronic acid serum (2%) paired with pro-vitamin B5 (panthenol) to boost moisture, plump fine lines, and support the skin barrier—delivered in a thicker "original" consistency 

Key Ingredients & Function

• Four types of sodium hyaluronate (low to high molecular weight + crosspolymer) ensure hydration across different skin layers, helping skin appear plumper and smoother 

• Panthenol (vitamin B5) supports ceramide synthesis and skin barrier repair, retaining moisture and reducing irritation 

• Supporting humectants and emollients like glycerin, pentylene glycol, propanediol, and Ahnfeltia concinna extract enhance feel and hydration without clogging pores 

• Clean formulation: no alcohol, fragrance, oils, silicones, gluten—it’s vegan, cruelty-free, and pH balanced (~6–7.5) 

Benefits

• Instant hydration & plumping – users notice smoother, softer skin and reduction in fine lines, especially when applied to damp skin 

• Barrier reinforcement – B5 contributes to healthier skin function and improved moisture retention 

• Lightweight, fast absorbing – despite the thicker original texture, it layers well under moisturizers and makeup
