Frequently Asked Questions

We process and hand your order to the carrier within 1–3 business days. U.S. delivery then takes 3–5 business days. If a carrier is delayed or you order during a peak period, allow up to 10 business days. Full detail on the Shipping Policy.

A flat $6.99 per order, however many items you buy. The amount is shown at checkout before you pay. All prices are in U.S. dollars.

We ship from the United States. Checkout also accepts addresses in Canada and Australia; those take longer than the U.S. estimate and any import duty or tax is set by the destination country and paid by the recipient. We do not ship elsewhere at the moment.

You get a confirmation email straight away and a tracking link once the carrier scans the parcel. If nothing has arrived within 3 business days, check spam and promotions, then email support@glycina.com with your order number. See Track Your Order.

Email us immediately. If the order has not shipped we will correct it. If it has, we will help you redirect it with the carrier or arrange a re-send when it comes back to us.

Email support@glycina.com with your order number and a photo if there is damage. We open a carrier claim and replace or refund the order at no cost to you.

Nobody — there is normally no return to make. In the rare case we need an item back to inspect a fault, we email you a prepaid label. Your cost is $0 either way, and there is no restocking fee.

Approved refunds go to your original payment method, usually within 5–10 business days of approval. Your bank decides how quickly it then shows on your statement. The $6.99 shipping charge is refunded too when a whole order is refunded.

It depends on the product and on you. Hydration and finish usually read within days; firmness, tone, and texture take consistent daily use across several weeks. Individual results vary, which is exactly why the guarantee runs 90 days.

Usually, yes — thinnest texture first, richest last, sunscreen in the morning. Some actives are better separated across morning and night. Tell us what you have and we will lay out an order that works.

On each product page. If something is missing or you need it for an allergy check, email support@glycina.com and we will send it.
