How to apply sunscreen correctly: Should you pat or rub it in to avoid depleting collagen?

In addition, remember to reapply every 2 hours, especially when outdoors, sweating, or after wiping your face, to maintain a stable protective layer for your skin.

You should pat gently instead of rubbing vigorously.

One common mistake when using sunscreen is rubbing or scrubbing vigorously to make it absorb faster. However, this method doesn't increase effectiveness and also causes the cream to be unevenly distributed on the skin. When rubbed, the cream tends to accumulate in wrinkles or "slip" away from important areas like the corners of the nose, around the eyes, or the hairline.

This inadvertently creates gaps, allowing UV rays to penetrate deep into the dermis – where collagen and elastin are located. In the long run, the skin easily loses its elasticity, becomes less firm, and ages faster.

One common mistake when using sunscreen is rubbing or pressing hard to make it absorb faster.

Conversely, gently patting or dabbing the cream in thin layers will help the product spread evenly across the skin's surface, maintaining stable coverage without disturbing the protective layer. At the same time, this method also reduces the pulling force on the skin – a factor that contributes to sagging over time.

Why does the way you apply it affect collagen?

Collagen is a component that helps skin maintain its elasticity and firmness. When sunscreen is not evenly applied or is lacking in certain areas, UVA and UVB rays can easily penetrate. This is a leading cause of collagen breakdown, resulting in dull skin, wrinkles, and loss of firmness.

Furthermore, vigorous rubbing when applying cream can create tension on the skin, affecting the structure of connective tissue. These seemingly minor, repeated mechanical actions contribute to accelerating the aging process.

Applying the correct amount is necessary for it to be truly effective.

Besides application technique, the amount of sunscreen used also plays a crucial role. Many people only apply a very thin layer for fear of clogging pores, but this significantly reduces the effectiveness of sun protection. In fact, if there isn't enough, the skin protection may only be half of the stated SPF rating.

These seemingly small, repetitive mechanical impacts, which occur every day, contribute to accelerating the aging process.

The standard amount for the face and neck is usually equivalent to about two fingertips. To avoid a heavy feeling on the face, you can divide it into 2–3 thin layers and gently pat each layer to ensure even coverage while still feeling comfortable.

The timing of application is also very important.

Another common mistake is applying sunscreen and then going outside immediately. In fact, many sunscreens need about 20-30 minutes to stabilize and form a protective film on the skin. If you go out in the sun too soon, the sunscreen won't have time to "work" and will easily wash off, reducing its effectiveness.

In addition, remember to reapply every 2 hours, especially when outdoors, sweating, or after wiping your face, to maintain a stable protective layer for your skin.

As you can see, applying sunscreen is not just a simple step but requires the right technique. Instead of rubbing vigorously, gently patting it on, combined with using the right amount and at the right time, will help the cream maximize its effectiveness while protecting collagen – the foundation that keeps skin firm, smooth, and youthful.
