Farmstay PDRN & Collagen Glow Bubble Serum

Shake the bottle up and down so the contents mix properly, then pump two or three times into your palm. The fine foam turns into a light serum as you spread it gently over your face. Use it after cleansing and toner, morning and evening, then follow with your moisturiser and, in the morning, sunscreen.

Only traces: the box lists collagen at 10 ppm and PDRN, as sodium DNA, at 0.1 ppm. The real work comes from niacinamide, fourth in the ingredient list, and adenosine, which is why the serum is certified in Korea for brightening and the appearance of wrinkles. Sunflower oil gives the dewy, glowing finish.

The formula contains cyanocobalamin, which is vitamin B12, a naturally pink-red ingredient that gives the serum its soft pink tint. The amount is small, so it doesn't stain the skin and spreads clear once applied. Like the other vitamins in Farmstay's PDRN range, it plays a supporting role next to niacinamide.

Both rely on niacinamide and adenosine and hold the Korean dual certification for brightening and wrinkle care. The Bubble Serum is an airy foam with sunflower oil, so it leaves a dewier glow. The Capsule Serum is a bouncy gel with floating capsules and feels lighter on oily skin. Choose based on the texture and finish you prefer.

It suits normal, dry and combination skin best. Sunflower oil is high in the formula and gives a dewy finish that oily skin may find too shiny, especially in summer. If your skin is oily, use one pump in the evening only, or choose the PDRN & Vitamin Capsule Serum, which is a lighter gel.

Niacinamide and adenosine are well tolerated by most skin types, and the formula includes soothing panthenol. It does contain fragrance and limonene, a fragrance allergen, which can irritate very reactive skin. Patch-test on your jawline for a few days before using it on your whole face, and stop if you notice redness or itching.

The dewy glow is visible right away. A brighter, more even-looking tone usually appears after four to eight weeks of twice-daily use, and softer-looking fine lines take a similar time with adenosine. Daily sunscreen is essential, because UV exposure keeps darkening marks and undoes brightening progress.

Yes. The foam texture is quick and easy, with nothing to measure: two pumps, spread, done. It suits men with dry or dull skin, uneven tone or the first fine lines. If your skin stings after shaving, wait a few minutes before applying, as the formula contains fragrance. Follow with a light moisturiser or sunscreen.
