There are numerous serum products on the market from various brands, so it’s important to choose one that suits your skin type and apply it correctly to maximize its benefits. Join us as we explore the two essential steps to applying serum effectively, guided by Doctor Hieu.

1 What is Serum?

Serum is a concentrated liquid or gel packed with premium active ingredients designed to deeply cleanse and nourish your skin. It comes in two primary forms: oil-based and water-based, each containing rich nutrients and micro-sized vitamins that penetrate the deeper layers of the skin for comprehensive skincare benefits.

2 The Two Essential Steps to Applying Serum Correctly with Doctor Hieu

With a plethora of serum options available, it’s crucial to know the proper application technique. Incorrect application can lead to dry skin, flaking, and inadequate moisture. Let’s delve into the four steps recommended by Doctor Hieu to ensure you’re applying your serum effectively.

Step 1 Dispense the Serum

It’s important not to overuse serum, as excessive amounts can be wasteful and ineffective. Doctor Hieu suggests the following two methods for dispensing the right amount:

Method 1: Dispense a moderate amount of serum into your palm, aiming for approximately five drops per application.

Method 2: After cleansing your face, apply one drop of serum to each zone – forehead, both cheeks, nose, and chin.

Method 3: Dispense one drop onto your hand and apply it to your face. Continue dispensing and applying until your skin feels sufficiently moisturized.

Method 4: Dispense serum into your palm and smooth it over your entire face. Note that this method tends to use up more serum than the others, so use it sparingly.

Dispensing Serum

The ideal time to apply serum is within two minutes after cleansing your face. At this point, your skin is still hydrated from the water, and there’s residual moisture on your face, creating an ideal environment for serum absorption. Waiting too long for your face to dry can reduce the effectiveness of the serum, leading to dryness and increased oil production.

Step 2 Apply the Serum

Method 1: After applying the serum, gently pat your skin to enhance absorption. Remember to pat in an upward and outward motion, as patting downward can cause skin sagging over time.

Method 2: Dispense the serum and apply it in an upward spiral motion from your neck to your forehead. A helpful tip is to use light pressure and gentle massage motions to further enhance absorption and stimulate blood circulation.

Method 3: Try using a warm iontophoresis device after applying the serum. This device helps open up the hair follicles, improving serum absorption. It’s best to use this method during the colder months.

Method 4: For those with sensitive or redness-prone skin, opt for a cold iontophoresis device instead. This device soothes and calms the skin, making it an excellent choice after serum application.
