Frequently Asked Questions

About the serum

What is PDRN?

PDRN (polydeoxyribonucleotide, listed as sodium DNA on ingredient labels) is an ingredient that became popular through Korean skincare. Our serum pairs it with a peptide complex in a lightweight, hydrating formula for fresh, dewy-looking skin.

What's the difference between Salmon DNA PDRN and Rose PDRN?

Salmon DNA PDRN is the classic formula, made with PDRN derived from salmon. Rose PDRN is a plant-derived option. Both have the same lightweight, fast-absorbing texture.

Who is it for?

It's made for all skin types: dry, oily, combination and sensitive. If you have sensitive skin, do a patch test before first use.

Where can I find the full ingredient list?

The full ingredient list is printed on the packaging. If you'd like to check it before ordering, email us and we'll send it to you.

I have a fish allergy. Which should I choose?

The Salmon DNA PDRN formula contains a salmon-derived ingredient. If you have a fish allergy or other sensitivities, check the ingredient list and speak with a healthcare professional before use.

Can I use it while pregnant or breastfeeding?

Please check with your doctor before adding any new skincare product during pregnancy or while breastfeeding.

Using the serum

How do I use it?

After cleansing and toning, apply a few drops to your face and neck and gently pat until absorbed. Follow with your moisturizer. Use morning and night, and finish with sunscreen in the morning.

Can I wear it under makeup?

Yes. It absorbs quickly and leaves no sticky residue, so it layers easily under sunscreen and makeup.

How long does one bottle last?

Each bottle holds 30 ml (1.01 fl oz). How long it lasts depends on how many drops you use and how often, but used twice a day most people find a bottle lasts several weeks.

How should I store it?

Keep the cap closed and store it in a cool, dry place away from direct sunlight. For external use only; avoid contact with eyes.
