The glass-skin glow Japan keeps chasing, and the one step that gets you there

You know the skin that looks lit from within. Dewy, a little bouncy, like she slept ten hours and drank two litres of water before you saw her. Japan has a word for it: 水光肌, mizu-hikari-hada, or water-glow skin. It is the look everyone wants right now, and it has almost nothing to do with owning more products.

Why does skin look flat even with a full routine?

Usually because nothing is prepping it to absorb anything. The moment your skin feels the slightest bit tight or dry, whatever you put on next just sits on top. Your toner, your moisturiser, that pricey serum, none of it really sinks in. So your face reads a bit dull and flat no matter how many steps you did. The problem is rarely the products. It is the missing step underneath them.

What is a booster, or 導入美容液?

A booster is the step you use first, on clean, just-washed skin, before your toner. Japanese women call it 導入美容液 (dounyuu-biyoueki), and most people outside Japan skip it completely. It softens the surface of your skin and opens the door, so everything you layer after it actually absorbs instead of pooling on top. It is the quiet reason a simple Japanese routine often looks better than a ten-step one.

What is PDRN, or salmon-DNA, skincare?

PDRN, better known as salmon-DNA, is the ingredient Japan is obsessed with in that booster step right now. It started life as a clinic treatment, the salmon DNA facial people used to whisper about, and it has become the at-home hero for that water-glow look. On @cosme, Japan's biggest beauty-review site, salmon-DNA boosters are some of the most talked-about launches around. The pull is simple: people say it leaves skin looking plump, smooth and glassy.

Our pick: the LipoPeel PDRN Pre-Serum

If you want to try the booster step with the salmon-DNA glow, this is where we would start you. The LipoPeel PDRN Pre-Serum is a Japanese booster that has earned a place on @cosme's shelves, and it quietly does two jobs at once. The salmon-DNA is the glow part. Alongside it are gentle exfoliating acids that lift away the dull, flaky surface, so skin looks clearer and finally catches the light. The finish is light and slippy, with no sticky film.

How do you use a PDRN pre-serum?

Keep it simple. Wash your face, then press three to five drops into skin while it is still slightly damp. Follow with your toner, then your moisturiser, and sunscreen in the morning. Two rules worth remembering: patch test first, and do not layer it the same night as a strong vitamin C or a retinol, because the acids on top of those can be too much for most skin. Alternate nights instead and you are fine.

Where can you buy Japanese PDRN skincare in Singapore?

Quick questions

Does a booster replace my serum? No. It goes before your usual routine, not instead of it. Think of it as the step that makes everything else work harder.

When exactly do I use it? First, right after cleansing, morning and night. Damp skin, three to five drops, pressed in gently.

Is salmon-DNA alright for sensitive skin? Most people get on well with it, but it does carry gentle acids, so patch test and start a few nights a week rather than twice a day.

This is general beauty information, not medical advice. Everyone's skin is different, so patch test new products, follow the directions on the pack, and see a doctor or pharmacist if you have a skin condition or any concerns. Contains salmon; avoid if you have a fish allergy.
