How to layer serum and sunscreen: Viscontour Serum Magnet first, then mesoestetic mesoprotech® mineral fluid SPF50+

 

October in Hong Kong is cloudy, but UV rays haven't gone anywhere. If you have sensitive skin and want to use a serum and sunscreen together, the most common problems are white cast and pilling (little flakes rolling up as you apply). Your sunscreen layer may also wipe off more easily with sweat or a face mask. This usually happens when sunscreen goes on before the serum has settled, or when too little sunscreen is used.

Key takeaways

  • Order: cleanse → serum → (day cream) → sunscreen
  • Wait about one minute after your serum, until your skin no longer feels tacky; shake your sunscreen well before use
  • Apply a generous amount of sunscreen, never a thin layer; there is no need to reapply serum when you top up sunscreen

What is the correct order for serum and sunscreen?

After cleansing, apply Viscontour Serum Magnet or the serum you are currently using. Wait about one minute, until your skin no longer feels tacky, then apply mesoestetic mesoprotech® mineral fluid SPF50+. Shake well before use, apply about 20 minutes before heading out, and cover your whole face evenly, including the sides of your ears and the front of your neck.

How much sunscreen should I use?

Your face needs about a quarter teaspoon, roughly two finger-lengths. If you use less, the actual protection will be noticeably lower than the SPF on the label.

How do I avoid white cast with mineral sunscreen?

Mineral (physical) sunscreens use zinc oxide and titanium dioxide as filters, so they tend to leave a white cast. This mesoestetic mineral fluid is lightly tinted to help minimise it. Dot the sunscreen onto your forehead, cheeks, nose and chin, then blend one area at a time.

Do I still need sunscreen on cloudy days?

Yes. Most UV rays still pass through thin cloud, and UVA can also pass through glass. Sitting by a window, riding in a car or walking for ten minutes in Central all expose you to UV. Check the Hong Kong Observatory's UV index before you head out.

What is the order if I use a day cream?

The order is serum → day cream → sunscreen. Apply your day cream thinly, and never layer it on top of sunscreen, as this can cause pilling and stop the sunscreen from spreading evenly. If the layers feel heavy or start to pill, use less day cream, not less sunscreen.

How often should I reapply sunscreen?

Outdoors, reapply about every two hours, and again after sweating, wiping your face or swimming. When you reapply, just apply sunscreen; there is no need to add more serum.

Precautions

If you feel stinging around your eyes, avoid the eyelids. If you have sensitive skin, try the product behind your ear or along your jawline for 24 hours first. This article is for general skincare reference only and is not medical advice.
