Cathy Doll Reju C Glass Skin Cream 0.2% PDRN 50ml

Glass skin is not a filter effect. It is what skin looks like when it holds enough water: light reflects off the surface evenly instead of scattering off dry patches. This cream is built around that mechanism, with a 13% humectant base (glycerin 6%, propylene glycol 7%) that pulls water into the skin and a shea butter, beeswax and dimethicone seal that keeps it there.

The headline active
PDRN (polydeoxyribonucleotide) is a chain of DNA fragments derived from salmon, and the ingredient Korean aesthetic clinics built their skin-booster reputation on. Here it is dosed at a verified 0.2% — the number on the front of the bottle is the number in the signed formula, to the decimal. On the skin, PDRN supports a firmer, bouncier look and softens the appearance of fine lines, with adenosine backing it on the same job.

The tone workers
Niacinamide at a full 1% is the formula's biggest brightening dose, working on the look of dullness and uneven tone. Four vitamin C forms add antioxidant support, led by a stabilized ethyl derivative that holds up in Gulf heat, with licorice root and mulberry bark extracts in the mix.

The defense layer
Grape seed oil at 1% brings antioxidant protection against the free-radical stress that dulls skin over time. Panthenol (vitamin B5), beta-glucan and allantoin keep the barrier calm and comfortable through daily use — useful in a formula meant to be worn morning and night, every day.

Tested the strict way
The finished cream went through a dermatological patch test at an independent ISO-certified lab: applied pure, under an occlusive patch, for 48 hours on 21 adults, then graded by a dermatologist. It scored 0.12 on a scale where anything under 0.25 classifies as non-irritating. That exposure is harsher than any real-world use.

1. After cleansing and drying your face, press the pump to dispense a suitable amount onto your fingertips (a pump or two covers face and neck).
2. Gently massage onto face and neck until fully absorbed.
3. Use morning and evening. It sits at the moisturizer step: after cleansing, toner and any serums.
4. In the morning, finish with sunscreen. The cream does the tone and hydration work; the SPF protects it.
5. Caution: Stop using and seek medical treatment if any signs of abnormality appear.
