Frequently asked questions

What is your return & exchange policy?

We’re here to help! If your order arrives with the wrong product, incorrect quantity, or any damage, simply reach out to us with your order details. We’ll be happy to assist you and make things right.

What is Decumar and who is it for?

Decumar is a skincare brand created for acne-prone, oily, and sensitive skin, with targeted care for post-acne dark spots. Our formulas combine Vietnamese herbal heritage with modern nano-science, and they're designed to fit into a simple daily routine.

What is Nano Curcumin, and why do you use it?

Curcumin is a compound found in turmeric, a botanical long used in Vietnamese skincare traditions. In our Nano formulas, it's processed into extremely small particles so it can be evenly dispersed in gels and creams. It helps support a clearer-looking, calmer-looking complexion.

Which Decumar product should I start with?

Breakouts and blemishes: Start with the Nano THC Blemish Gel Cream or the Promax Blemish Spot Gel.
Dark spots after acne: Try the Advanced Nano Dark Spot Gel Cream.
Cleansing: Choose a Nano THC or Promax cleansing gel, depending on your skin type.
Body breakouts: Use the Advanced Blemish Body Wash and Body Spray.

How do I use Decumar products?

Cleanse first, then apply a thin layer of gel or cream to clean, dry skin (morning and/or evening, follow the label of each product). Apply sunscreen during the day. Please follow the directions on each product's packaging.

Is Decumar safe for sensitive skin?

Our formulas are designed with sensitive, acne-prone skin in mind. We recommend a patch test first, and stopping use if irritation occurs. If you're pregnant, nursing, or have a skin condition, check with your doctor first.
