Orders placed internationally (outside the U.S), are subject to duties, taxes, tariffs, and other fees defined under the destination country’s laws and regulations. Unfortunately, we cannot predict the costs of these fees, but they can range up to 18% of the total cost of goods. If customs charges occur, you, as the buyer, are 100% responsible for these charges. We, the seller, are not responsible for any customs charges. We are also not responsible for packages that are refused due to high duties and taxes; packages that don't clear customs due to country restrictions; or any additional package delays. After you receive your tracking number, it is your responsibility to track the progress of the package, as you will not always be notified of customs holding your package. If you decide to refuse your package or not pay the duties, it will be sent back to us. Please note, if you choose not to pay duties on import and return the package, we will refund your order less any shipping paid. The cost of shipping is paid directly to the shipping provider, and therefor is not refundable.

Best line of skincare products I've ever used, Petunia is affordable and effective.

This serum has been very effective on my horizontal and vertical frown lines. I've never really had a huge issue with them, but they have smoothed and softened out. Great experience and I'm really excited to see further transformations in my skin!

My skin looks like it's repairing itself

This serum has really helped my skin become tighter and softer without making it dry. I hate in the past when a product will dry my skin out and everything feels tight and it hurts to even smile! Well you don't get that with this product that's for sure, but don't use this every night or it will start flaking your skin. I use it 2-3 times a week and see good results with it.

A must have in your skin care products

This retinol is a clear thick gel that absorbs fast into your skin. There is no burning sensation or sticky residue left behind and surprisingly doesn't feel too dry after. I still use a moisturizer no matter what but i'm pretty sure I could wear this serum without a moisturizer and my skin would still be fine. But what I really like about this product is that it's lightened these little dark spots I have around my cheeks.. their not sun spots and I'm not sure if their age spots but they're just tiny little dark spots and I've noticed that since using their retinol it's become lighter.

Acne cleared up and the scars are starting to fade

I use this serum to control the hormonal acne and scars on my face. I also use this with their vitamin C serum. I apply the retinol once every other night and the vitamin c serum every night. I also use a sunscreen moisturizer as protection during the day. I saw slight improvements in a week. My acne started clearing up much faster and the scars too. I probably need to use it for a few more weeks to fully achieve the results I want since I know that my skin has a long way to go. But I'm very happy with the fast improvements already.

My skin always looks better with this

This retinol serum has been part of my skincare routine for months, and my 54-year-old skin always looks better with this. This serum has a perfect balance of retinol, hyaluronic acid, plus other organic ingredients. Thank you for creating these great products at such a great price! Petunia is going to be my lifelong skin buddy now!
