Frequently asked questions

Straight answers about PDRN Glow Serum, shipping and our 30-day money back promise.

How do I apply it?

Morning and night, 3 to 4 drops from the dropper. Press them into clean skin, face and neck, then follow with moisturizer. Add sunscreen in the morning.

What does PDRN do in this serum?

The Korean skin clinic secret, in a daily serum. PDRN is a purified DNA fragment ingredient that's popular in Korean skincare for a bouncy, glowy look. In our serum it works with a peptide, hyaluronic acid, glycerin and panthenol, and the look you get comes from all of them together.

Will it help with fine lines and wrinkles?

It reduces the look of fine lines and wrinkles with consistent use. The peptide, hyaluronic acid, glycerin and PDRN work together so skin looks smoother, plumper and dewier. It's a cosmetic, so it works on how skin looks and feels. Results vary.

When will I notice a difference?

You'll feel the hydration as you press it in. The look of fine lines softens with consistent daily use, morning and night, which is why the 2 and 3 bottle packs save the most. Results vary.

Will it break me out or irritate sensitive skin?

Patch test first. Everyone's skin is different, so we can't promise how yours will react. The serum is lightweight and fragrance free with no niacinamide. Try it on a small area for a day and stop if irritation happens.

Is it right for mature skin?

Yes. It's made for skin that's starting to look drier, flatter or more lined, at any age. It layers under moisturizer and makeup.

Is it fragrance free?

The serum is. No fragrance, parfum or essential oils. The Gua Sha Oil has no added fragrance. It's a blend of plant oils and contains sweet almond oil, so skip it if you have a tree nut allergy.

What is your PDRN made from?

Salmon DNA. Our PDRN is salmon derived and makes up 0.25% of the formula, so this serum isn't vegan or fish free. If you avoid fish ingredients, it isn't the right pick for you. The look you get comes from PDRN working with the peptide, hyaluronic acid, glycerin and panthenol together.

Does it have niacinamide?

No. Many popular PDRN serums include it. If you'd rather skip it, this one leaves it out, and it's fragrance free too.

Can I use it with retinol or vitamin C?

Yes. It's a simple hydrating serum. Apply your active first or use them at different times of day, and wear sunscreen in the morning.

Can I use it while pregnant or nursing?

Ask your doctor first and show them the ingredient list on the product page.

Can men use it?

Yes. It's fragrance free and suits anyone who wants a hydrated, plumper look. Press it in after cleansing, then moisturize.

Is the gua sha tool included?

No. The Glow Duo is the serum and the oil. The oil works with any stone or steel gua sha tool, or just your fingertips.

How much is in each bottle?

1 fl oz (30 ml). That goes for both the serum and the Gua Sha Oil. Made in the USA with globally sourced ingredients.
