Questions, answered plainly.
Why only 1 or 3 months?
Hydroquinone is used in courses, usually 3 to 6 months, then a break. Your provider decides when to continue.
Can I use it on my whole face?
Apply it to spots and patches only, unless your provider tells you otherwise.
What about sunscreen?
Daily SPF 30 or higher is required. Sun exposure brings pigment back.
Can I use it with tretinoin?
Often, yes. Tretinoin can help hydroquinone work. Your provider decides if the combination fits your skin.
What if I'm not prescribed?
You get an automatic refund, in full. No need to ask.
How does my plan work?
Your treatment refills on the schedule you choose, every 1, 3 or 6 months, so you never run out. Change, pause or cancel anytime from your account or by contacting support.
Can I use my HSA or FSA?
Yes. You can pay with your HSA or FSA card at checkout.
Important safety information
Use only as directed, usually in courses of 3 to 6 months followed by a break. Stop and contact your care team if treated skin darkens or turns blue-black. Not for use during pregnancy or while breastfeeding. Mild redness, dryness or peeling can occur.
Your provider reviews your health history and medications before prescribing. Message your care team with any side effects.
