Why Choose One Over the Other?
The choice between these two often comes down to your personal skin tolerance and goals. UKLash offers two prostaglandin-free formulas, which include the Complex Peptide version and their Sensitive line. This is a massive win for the brand, as it caters to those who need a break from more potent active ingredients.
It is worth noting that some users prefer the original formula over this peptide version, often citing that the results with the original are faster. Conversely, I found the peptide version to be a superior choice for daily, long-term use without the risk of irritation.

If you have already achieved your desired length with the Original Lash Serum - with low levels of prostaglandin analogues, switching to the Complex Peptide formula is a smart move for maintenance. It provides the essential amino acids needed to maintain the gains you’ve worked so hard for, all while being formulated for enhanced comfort.
