Farmstay PDRN & Vitamin Advanced Capsule Serum

Very little. PDRN is listed as sodium DNA at 1 ppm, which is 0.0001% of the formula, so it plays a symbolic rather than active role. This isn't comparable to clinic PDRN treatments. The serum's real work comes from 2% niacinamide and adenosine, which is why it's certified in Korea for brightening and wrinkle care.

The capsules contain vitamin C in two forms, plus vitamins B5, B6 and E, but the box lists them in tiny amounts, parts per million or less. The vitamin that does the real work is niacinamide, which is vitamin B3, at 2%. It helps even out skin tone, supports the skin barrier and suits almost every skin type.

Morning and evening, after cleansing and toner, apply one or two pumps and smooth evenly over your face. Pat gently until absorbed, then follow with your moisturiser. In the morning, always finish with sunscreen, as brightening results last only when skin is protected from UV. Visible changes in tone usually take four to eight weeks of regular use.

In Korea, a product can only claim brightening or wrinkle care after the national food and drug safety authority reviews its active ingredients and their amounts. This serum holds a dual certification: brightening, thanks to 2% niacinamide, and wrinkle care, thanks to adenosine. It's a meaningful signal that the key claims are backed by recognised actives.

Niacinamide at 2% is gentle and well tolerated by most skin types, including sensitive skin. The formula does contain fragrance, which is the main thing to watch if your skin is reactive. Patch-test on your jawline for a few days before using it on your whole face. If you notice redness or stinging, stop using it.

Yes. Niacinamide and adenosine pair well with both. If you use a separate vitamin C serum, apply it in the morning before this one. If you use retinol, keep it for the evening and apply this serum first, or alternate nights if your skin is new to retinol. Always wear sunscreen during the day.

Yes. It's a light, bouncy gel that absorbs quickly without leaving a greasy film, so it works well for oily and combination skin, even in summer. Niacinamide also helps balance the look of excess shine and visible pores over time. Follow with a light gel moisturiser if your skin is oily, or a richer cream if it's dry.

Yes. It works the same on any skin and is especially useful for men dealing with uneven tone, post-shave redness marks or the first fine lines. One or two pumps after cleansing and shaving are enough, followed by moisturiser. The light gel texture suits men who dislike heavy products.
