How do I use P.Happi?

With the bottle standing upright apply one pump to the vulva, labia and perineum area (front to back to avoid contamination). For optimal protection make part of your morning and evening routine.

When you first open and use the bottle you will need to pump a few times. This is due to the filling process. We like to avoid leaks when we're filling the bottles with 20g of P.Happi!

When should I use P.Happi?

We recommend you use P.Happi daily to maintain protection.  Use during higher risk times when you are more sexually active, stressed or traveling a lot. For example periods of sexual activity or when traveling.

Who can use P.Happi?

Everyone over the age of 18 who is not pregnant or breast feeding can use P.Happi. Further studies are planned so that everyone can use it. P.Happi is especially suitable for women who suffer from recurrent symptoms. 

Can pregnant women use P.Happi?

We have not done studies with pregnant women yet and so we do not currently advise pregnant women to use P.Happi.

How is P.Happi tested?

We carry out lots of studies in our own lab and third party labs. P.Happi is dermatology tested including tested on sensitive skin. We have conducted clinical tests and ongoing microbiome studies with women suffering from recurring issues. These are externally verified  by a third party.

Yes it is. P.Happi is not tested on animals, it has no GMO and is free from animal components.

Is P.Happi suitable for vegetarians?

P.Happi is vegetarian friendly!

What does P.Happi smell like?

P.Happi is fragrance free! We haven't added a fragrance to the serum to avoid any irritation this may cause and keep the product as natural as possible. Some users have noticed an earthy scent. This comes from the natural ingredient B.Y.M. 1405 but this fades after application.

Is P.Happi sustainable?

P.Happi is made in the UK to avoid any extensive shipments and thus to maintain a lower carbon footprint. You may notice that we do not include a leaflet in our packaging, this is to avoid unnecessary wastage and wrapping to reduce plastic usage.

Where can I buy P.Happi?

You can buy P.Happi directly from later in 2024. It will be available to purchase on a subscription basis so that you never run out of the product.

I forgot to apply the serum. What should I do?

Simply make a note on your calendar of the times or days when you forgot to apply the serum and continue applying it as usual from then on. You do not need to apply it multiple times to make up for a forgotten application.  Remember, P.Happi® is most effective when applied every morning and night.

I got my period. Should I continue applying the serum and testing my urine?

No problem! Continue applying the serum even when you have your period. 

Why do you use silicones in the serum and are they safe?

We use silicones in our product to create the stability and consistency of the serum that you love! Silicones have been proven to be safe for use in care products for decades.

There isn’t currently an alternative that we can use in place of silicones that will provide the same level of functionality, quality and safety we want. We will however continue to research and develop our products ensuring the quality of our ingredients. Please consult a doctor if you have a specific allergy to silicones.
