With 87,000+ reviews (and counting), TruSkin Naturals is by far the most popular vitamin C serum ever!
This $20 vitamin C serum is formulated, manufactured, and bottled in the USA for maximum freshness and comes with an industry-leading 90-day money back guarantee.
Instead of L-ascorbic acid, TruSkin Naturals uses sodium ascorbyl phosphate (SAP), a common vitamin C derivative.
While SAP is more stable and offers a longer shelf life, studies show that SAP is less effective than L-AA as it must first be converted into L-AA by your body (Stamford, 2012).
One study found that at least 10x the concentration of SAP was required to match the effects of L-AA for stimulating collagen production (Geesin, 1993).
Nonetheless, at this price point, most vitamin C serums on the market use vitamin C derivatives like SAP (Vichy is a noteworthy exception that still uses 15% L-AA).
While SAP helps brighten dark spots, MSM (organic sulfur) prevents collagen breakdown, reduces inflammation, and detoxifies your skin by increasing cell wall permeability.
Moreover, MSM requires plenty of vitamin C to function, making SAP the perfect (dance) partner! (Era Organics)
Hyaluronic acid, vitamin E, and botanicals like aloe vera, gotu kola, horsetail, dandelion, and geranium round out this formula with their hydrating and soothing properties.
With 87,000+ reviews and a $20 price tag, it's hard not to recommend TruSkin Naturals.
However, it's not as potent as my earlier recommendations (SAP is not as effective as L-AA) and the actual concentration of vitamin C is not disclosed, either.
For about $10 more, Vichy LiftActiv Vitamin C Serum is an outstanding budget option as well with 15% L-AA instead of SAP (just keep in mind it's a 0.34 oz bottle size).
