How does our clinically proven Growth Treatment work?

Let’s get into the technicalities!

The Mylash/Opti Laboratories Growth Treatment works because it contains an active ingredient, bimatoprost. Bimatoprost is a prostaglandin analogue, a synthetic version of a class of naturally occurring molecules. Prostaglandins are a bit like hormones – a signal that your body uses to regulate processes like hair growth.

Your lashes grow in a cycle with three phases:

  • Anagen (active growth phase)
  • Catagen (transition phase)
  • Telogen (resting phase)

The bimatoprost in the Growth Treatment mimics the body’s natural signals, extending the anagen phase of the lash’s growth. As a result, your eyelashes grow for a longer period of time, resulting in thicker, stronger, and longer lashes.

Do eyelash “growth” serums work the same way?

The Growth Treatment is not the same as an eyelash serum. Most serums are designed to condition and nourish your lashes, but they don’t contain an active growth ingredient like bimatoprost, so they can’t actually grow your lashes.

Opti Laboratories has recently released a complementary Sun Protect Serum for lashes and brows. We’re pleased to announce that it is a finalist in the Live That Glow Independent Beauty Awards 2025.

Who are Mylash and Opti Laboratories?

Mylash and Opti Laboratories are run by the same team. We’re gradually moving our business over from Mylash to Opti Labs.

We are the experts in eyelash care. Over the last 16 years we have helped thousands of people to grow their eyelashes with our prescription strength Growth Treatment and expert advice.

We offer an online service, run by UK-based doctors. That means that we professionally supervise and regulate your treatment, and deliver to your door.

Once you have placed your online order, we’ll send you a link to an online medical questionnaire. Our doctors review each and every questionnaire before approving treatment and will be in contact if required.

Our doctors are only likely to refuse treatment in the event of pre-existing eye conditions, pregnancy or breastfeeding. If we have to refuse treatment, we won’t charge for payment.

Mylash Growth Treatment is a prescription-only product and are not available at high street retailers like Boots. We warn against unregulated treatments offered without medical advice.

“The result is absolutely phenomenal.”
