Is this serum worth it?

It is a reasonable pick if you want peptides, ceramides and NAD+ in one step. If you already use a peptide serum and a barrier cream, the overlap may not justify another bottle.

How does it compare with a retinol serum?

This serum focuses on hydration, barrier support and firmness with no retinol, so it is gentler and can be used alongside retinol. Retinol remains the better-proven option for fine lines and texture.

How long will a 30 ml bottle last?

At two to three drops once or twice daily, a 30 ml bottle typically lasts about one to two months. Using it on the neck shortens that.

Can I use it with vitamin C or retinol?

Yes. Peptides and ceramides layer well under vitamin C in the morning and retinol at night. Introduce one new product at a time if your skin is sensitive.

You get one 30 ml (1.01 fl oz) serum bottle. The listing does not include a dropper size, spatula or extra samples.

Our take on the EQQUALBERRY NAD+ Peptide Boosting Facial Serum

The EQQUALBERRY NAD+ Peptide Boosting Facial Serum is a 30 ml (1.01 fl oz) Korean skincare serum built around a 14-peptide complex, five ceramides and NAD+ to support firmness and the skin barrier. It is a lightweight, layerable serum aimed at early signs of aging and dull, dehydrated skin. It is a newer product, first available in December 2025, so long-term owner feedback is still thin.
