Notable Features Affiliate product – ZetaClear is highly marketed by third parties across the internet. Consistency & Scent – Zetaclear is a thicker liquid with a pine like scent. Small Size – The bottle of ZetaClear we received is .5 fl oz/ 15ml. This is the smallest size out of any brand we reviewed. We expect you would require multiple bottles due to its size.

“It is really good…. My mother is elderly, I haven’t notice, when did that developed, and she can’t take oral pills, because of her liver, just in case we try Zeta. I was surprised, when I notice, that her toe nail grew out half way already. We are very pleased with results.”

Customer Satisfaction

Unfortunately, there appear to be more negative reviews across the internet and on websites like Amazon or other shopping platforms. This is common with more popular products… although, the volume of negative reviews is concerning and seem to stem from unclear return policies and misunderstanding regarding their “Satisfaction Guarantee” on website.


https://zetaclear.com ZetaClear marketed as a “Clear Nail Solution” on their label as seen in the provided photos. It contains essential oils and extracts in addition to Undecylenic Acid. According to the label, this product contains 10% Undecylenic Acid. One concern we have with the product is some of the claims it makes. It’s unclear to us how this product reacts to the nail as we have been unable to locate any studies. Although there appears to be many mixed reviews regarding this product, we should note it very similar to other products containing similar ingredients – only at a slightly higher price point.

Review of ZetaClear

ZetaClear Snapshot


Clear Guard Technology ZetaClear is one of the most highly marketed products on the internet in its category. In part, it’s due to the quality of the product and in part it’s due to the competitive affiliate structure they have setup for promoting it. This is not to say that ZetaClear is not an effective – it does contain notable ingredients. It does, to some extent, explain a lot of the controversy around the product and it’s popularity in advertising by 3rd parties (we do not receive any affiliate income as a result of this review).

I saw very little difference in the course of 2 bottles. Restocking fee was asked for but I refused to pay it.
