Farmstay Real Blueberry Essence Mask

The pouch lists blueberry extract at 50 ppm, which is 0.005% of the essence, so it's a supporting touch rather than the main active. The moisture boost you feel comes from glycerin, propylene glycol and betaine, which draw water into the skin and leave it looking plumper and dewier straight after use.

Cleanse your face and apply toner. Open the pouch, unfold the sheet and smooth it evenly over your face, avoiding the eyes and mouth. Relax for 15 to 20 minutes, then remove the sheet and gently pat the remaining essence into your skin. There's no need to rinse. Follow with moisturiser to seal in the hydration.

Two or three times a week is a good routine for most skin types. Because it's a simple hydrating mask with no exfoliating acids, you can also use one daily for a few days before an event or when your skin feels especially dry, for example after a flight or in winter heating.

Both work, and the pouch suggests each. For a refreshing, calming feel, keep the sealed pouch in the fridge before use, which is great in summer or on puffy mornings. For a cosier treat in winter, place the sealed pouch in warm water for two to three minutes before opening it.

Be careful if your skin is reactive. The essence contains alcohol denat. high in the ingredient list, plus fragrance, which can sting or dry out sensitive skin. Most normal, dry and combination skin tolerates it well. If you're unsure, try it on your jawline for a few minutes first, and remove it if you feel burning.

Yes, it's one of the best uses for a hydrating mask. Use it in the morning after cleansing, pat in the leftover essence, then apply a light moisturiser and wait a minute before foundation. Well-hydrated skin helps makeup sit more smoothly and look less cakey, especially on dry patches around the nose and cheeks.

Yes. A sheet mask is one of the easiest ways for men to start with Korean skincare: open, apply, relax for 15 minutes, done. It's especially useful for skin that feels tight after shaving or a long day. If you have a beard, the sheet won't sit flat there, so focus on the forehead, cheeks and nose.

Use it straight away rather than saving it. Smooth the extra essence over your neck, chest or the backs of your hands for a little extra hydration. Once the pouch is open, the essence is exposed to air and bacteria, so don't keep it for the next day. Each mask is designed for one use.
