Skin Salt vs Ultima Replenisher: Which Is Right for You?
Medically reviewed by Dr. Mark Rosenberg, MD Updated
Ultima is a very low-sodium electrolyte, with 55mg per serving. Skin Salt carries 500mg of sodium for hydration you can actually feel, plus DermaVal, hyaluronic acid, ceramides and vitamin C for your skin. Both are sugar-free, but only one is built to work for your skin.

Sodium: 55mg vs 500mg
Sodium is the electrolyte that holds water in your body, ready for when you need it. At 55mg, Ultima is gentle, but it's a small amount if you're active, sweating, or drinking electrolytes to actually feel more hydrated.
Skin Salt's 500mg is the right amount for most people who are moderately active, and still half of what many athlete-focused brands use, so you can enjoy a few sticks a day.
What Skin Salt adds
- DermaVal (50mg), a patented superfood extract clinically proven to halt the destruction of collagen by 72% and elastin by 98%.¹
- Hyaluronic acid (40mg), a cellular sponge for moisture and radiance.
- Ceramides (5mg), which help fortify and rebuild your skin barrier.
- Vitamin C (18mg), which supports collagen synthesis.
Ultima sells DermaVal separately, in its Collagen Defense line. Skin Salt combines DermaVal with hyaluronic acid, ceramides, vitamin C and 500mg of sodium in a single stick, so one drink does it all.
Where Ultima shines
Ultima offers a broad mix of minerals, including calcium, phosphorus and zinc, in plenty of flavors. It's a light everyday sipper. But with so little sodium and nothing for your skin in the core formula, it does less of what most people are after.
Taste
Both are sugar-free and stevia-sweetened. Skin Salt adds monk fruit for a rounder, more refreshing 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
Ultima is a gentle, low-sodium sipper. If you want hydration you can feel and skin support from the same daily drink, Skin Salt does both, with skin boosters clinically proven to protect your collagen and elastin up to 98%.¹
Frequently asked questions
Is 500mg of sodium too much?
For most moderately active people, no. It's about 22% of the Daily Value, and half of what many electrolyte brands use. If you've been advised to watch your sodium, check with your healthcare provider.
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.
