Question 1

How do transdermal patches actually work?

Accepted Answer

Active ingredients are suspended in an adhesive matrix that sits flush against your skin. Body heat activates a slow, steady release through the stratum corneum and into your bloodstream — bypassing your stomach and liver entirely.

Question 2

When does Tova launch in my country?

Accepted Answer

Join the waitlist and you'll be the first to know — plus a 15% welcome offer.

Question 3

Where do you ship?

Accepted Answer

Singapore, Malaysia and the Philippines in late 2026. More SEA markets coming soon!

Question 4

Are the patches safe for sensitive skin?

Accepted Answer

Always double check the ingredients list on the back first in case you have allergies. If you have known skin sensitivities, do a short patch test on your inner arm first.

Question 5

Can I wear a patch in the shower or pool?

Accepted Answer

We don't recommend exposing a patch to water. For best performance, ensure the skin is completely clean and dry before adding a patch.

Question 6

How is the Berberine Patch different from oral berberine?

Accepted Answer

Oral berberine is famous for causing GI upset — bloating, cramping, loose stools — because it's a gut irritant. Our transdermal delivery skips the gut entirely, giving you the metabolic benefits without the discomfort.

Question 7

Are your patches vegan?

Accepted Answer

The Sleep and Berberine patches are fully vegan. The Glow Patch contains marine collagen, so it's not vegan — but it is sustainably sourced.
