Learn the signs your Multi-Acid Foot Peel Refill is running low or no longer effective, how often to replace it, and what to expect from multi-acid foot peel results at home.
Quick answer
Replace your Multi-Acid Foot Peel Refill when you've used all three treatments in the bottle, when the liquid looks discolored or has a strong off smell, or when you notice peeling results fading despite consistent monthly use. Each refill bottle is designed for three peeling treatments with the reusable silicone booties, so most people need a new refill every three months.
How many treatments are in one Multi-Acid Foot Peel Refill?
Each refill bottle contains three peeling treatments. That's a full quarter of monthly foot peels if you stay on schedule. The bottle is meant to pair with the reusable silicone booties, so you're only replacing the liquid, not the whole system. If you peel more often than once a month, you'll go through a bottle faster. If you skip months, the liquid may degrade before you finish it.
What are the signs your foot peel refill is no longer working?
The clearest sign is a change in results. If your feet used to shed visible flakes of dead skin after each treatment and now barely peel, the acids may have lost potency. Other signs include a noticeable color shift in the liquid, a sour or chemical smell that wasn't there before, or a thicker, cloudy texture. Any of these suggest it's time for a fresh bottle rather than pushing through another treatment.
How often should you replace your foot peel refill?
Plan on a new refill every three months if you peel monthly. That aligns with the three treatments per bottle. If you use the peel every six weeks instead, one bottle stretches to about four and a half months, but check the liquid before each use. Storage matters too: keep the bottle tightly closed, upright, and away from direct sun or steamy bathrooms, which can shorten its useful life.
What do multi-acid foot peel results actually look like over time?
With consistent monthly use, the salicylic acid and three other acids in the formula gradually dissolve built-up dead skin while allantoin conditions the soles. You'll typically see smoother, softer feet after the first few treatments, with less hard, dry buildup on heels and the balls of your feet. Results are cumulative, so missing refills or stretching the liquid too thin can stall your progress.
Can you use the refill with any silicone booties?
The refill is designed for the StackedSkincare reusable silicone booties, not disposable plastic wraps or other brands. The booties are eco-friendly and reusable, so you only repurchase the liquid. If your booties have tears, residue buildup, or no longer fit snugly, replace those separately. A loose fit lets the liquid pool unevenly and reduces contact with rough patches.
Foot peel refill FAQ
- How do I know the refill is empty?
- The bottle holds three treatments. Once you've poured the last one, there's no more liquid to dispense. Don't try to stretch it with water or mix in other products. Mark your calendar after the third peel so you can reorder before your next monthly session.
- Can I use an expired or old refill?
- If the liquid has changed color, smells off, or looks cloudy, don't use it. Acids can degrade over time, especially in heat or humidity. Store the bottle closed, upright, and out of the shower steam to get the full three treatments.
- Do I need new booties with every refill?
- No. The silicone booties are reusable. Only replace them if they're torn, stretched out, or coated in stubborn residue that won't rinse clean. Rinse and dry the booties thoroughly after each use to keep them ready for the next refill.
- What if I miss a month?
- You can pick up where you left off, but check the liquid first. If it's been more than a few months since you opened the bottle, the acids may be less effective. Consistency gives the best multi-acid foot peel results, so aim for monthly use when possible.
- How long until I see results from a fresh refill?
- Most people notice smoother, softer feet after the first few treatments with consistent use. Hard, dry buildup on heels and soles gradually diminishes. Give it two to three monthly peels before judging results, and don't skip refills in between.
Product facts
- Multi-Acid Foot Peel Refill: Each refill bottle contains three peeling treatments used with the silky soft eco-friendly reusable silicone booties. This tells you exactly how long one refill lasts, so you can plan replacements every three months if you peel monthly.
- Multi-Acid Foot Peel Refill: Salicylic acid plus three other acids deeply exfoliates hard dry skin while allantoin conditions the bottoms of your feet. The multi-acid blend targets buildup rather than just moisturizing, which is why consistent refills matter for maintaining soft soles.
