Which Eyelash Serum?

[PrimeSeason]

I’m in the market for an eyelash serum. In the past I have used Revitalash and UK Lash.

Any suggestions as to which product is the best on the market currently, please?

Thanks.

Organic castor oil, used firstly as a makeup remover for my eyes, then a wipe over with micellar and apply more oil to my eyelashes and brows with a spoolie brush. Cheap as chips (less than a tenner for a bottle that’ll easily last 6 months) and just as good in my experience.

I don't use one regularly but I do use a brow serum .
DD has tried -
Revitalash
UKLash
The Ordinary
Castor Oil

Out of all of these Revitalash is her favourite .
I use Revitabrow (it is brilliant if I use it properly )

I found The Ordinary stung my eyes ( used on eyelashes and had stinging the next day so I knew it was that . Tried again, same issue)
DD found UK Lash irritated her eyes . I found the UKBrow went off/smelled bad
Neither of us liked castor oil.

So-TLDR
Revitalash (£ but worth it )

Another vote for Revitalash

Peptides particularly myristoyl pentapeptide-17 and biotinoyl tripeptide-1 have the most evidence for supporting lash growth and density. Biotin in topical form has more limited evidence than oral biotin but appears in most effective formulas.

Thanks everyone.
Revitalash sounds like the best option
