4 Products Failed Our Review

Most Nail & Skin Health Supplements Are a Waste of Money

We reviewed 4 nail & skin health products. None met our approval criteria. The rest failed for reasons the industry doesn't want you to know.

Why 4 Products Failed

Most nail & skin health supplements fail for the same 3 reasons:

1

Underdosed ingredients that look good on the label but won't actually work

2

Proprietary blends that hide how little of each ingredient you're getting

3

Marketing claims that far exceed what the research actually supports

What a Nail & Skin Health Supplement Must Have to Pass

We don't recommend products lightly. To earn our approval, a nail & skin health supplement must:

Realistic timeline for nail/skin improvements
No cure claims for fungal infections
Transparent ingredient list
Recommends seeing a dermatologist for infections
Honest about supplements vs. topical treatments
Quality manufacturing standards
