We tested every available code. Below is the only coupon that applies a real discount at checkout — no typing needed. Click the link and the discounted price is already applied.
We verified all codes on March 19, 2024. The official Kerassentials website does not use promotional codes in a coupon field — the discount is applied automatically when you access through the active promotion link. Any “code” you type at checkout won’t make a difference.
What actually matters is which kit you choose. The 6-bottle kit has the largest per-bottle discount currently available: $49 per bottle, compared to $79 in the basic 2-bottle kit — that’s $780 in total savings.

Kerassentials is formulated with oils backed by published research: tea tree oil (with documented antifungal properties), lavender, organic flaxseed oil, and undecylenic acid — a fatty acid used in topical fungal treatments for decades.
It is not a medication and does not replace medical consultation, but the composition is consistent with what the literature points to for supporting nails and skin affected by fungus.
3+3 bottle kit — biggest discount
"I used the discount link and saved a lot. Product arrived in 8 days and I'm already in my second week of use. The itching is completely gone."
"The 60-day guarantee convinced me to try it. I've been struggling with foot fungus since high school — this is the only thing that actually helped."
"Took the 6-bottle kit through the coupon. Takes a little time but my nail started growing back healthy after about 6 weeks."
