Skin Salt vs k2o: Which Beauty Electrolyte Is Right for You?
Medically reviewed by Dr. Mark Rosenberg, MD Updated
Both are beauty electrolytes, but they take opposite approaches to collagen. k2o adds collagen peptides. Skin Salt protects the collagen and elastin you already have with DermaVal, clinically proven to halt the destruction of collagen by 72% and elastin by 98%.¹ Skin Salt also carries twice the sodium, and your first box costs about half as much per stick.

Adding collagen vs protecting it
Around the age of 30, two enzymes, collagenase and elastase, begin breaking down the collagen and elastin that keep skin firm and smooth. Adding collagen is great, but it doesn't change the fact that your skin is under attack around the clock.
That's where Skin Salt is different. DermaVal wraps collagen and elastin in invisible "bioshields" that help them stand up to those enzymes, protecting what you already have. We love collagen too, but it mixes thick into water, and we wanted Skin Salt to be light, smooth and crisp.
Sodium and hydration
k2o carries 260mg of sodium. Skin Salt carries 500mg, the right amount for most people who are moderately active, so the hydration side is more noticeable, especially on active or hot days.
Where k2o shines
k2o uses Verisol collagen peptides at the dose its studies use, adds five electrolytes, and comes from a well-known brand. It's a credible beauty drink. But it costs about twice as much per stick, isn't vegan, and doesn't protect the collagen and elastin your skin already has.
Taste
Both are stevia-sweetened. Skin Salt adds monk fruit for a rounder sweetness, in four flavors: Summer Peach, Passion Fruit Sunrise, Triple Berry Burst and Lemon Lime Spritz.
“I try every electrolyte product lol, I didn't expect Skin Salt would taste so good though, it's honestly the best one out there and that's before the skin benefits.”

The bottom line
k2o adds collagen. Skin Salt protects the collagen and elastin you already have, with more sodium for real hydration, a vegan formula, and a lower price on your first box. And if you already take collagen, Skin Salt adds the line of defense collagen alone can't.
Frequently asked questions
Can I take Skin Salt and collagen together?
Yes. DermaVal adds a line of defense for the collagen you already have, so it can improve the results from collagen you're already taking.
What about during pregnancy?
k2o's label says not to use it if pregnant or nursing. For Skin Salt, we recommend talking to your healthcare provider before starting.
Can I switch to Skin Salt?
Yes. Skin Salt has a balanced mix of sodium, potassium and magnesium, so it can replace your other electrolyte drinks. On your most active days, just add a second stick.
