How Cosmetic Microneedling Supports Your Skincare Routine

Cosmetic microneedling supports the skin’s natural renewal process by creating fine contact points on the skin’s surface. As part of a consistent skincare routine, this process helps support smoother-looking texture and a refreshed complexion.

While topical skincare products such as serums and creams help hydrate and care for the skin’s surface, cosmetic microneedling can support more even application of skincare formulas. The fine contact points created during use allow cosmetic products to spread more evenly across the skin as part of a regular beauty routine.

Dr. Pen cosmetic skincare devices are designed to support controlled surface contact and help maintain a smoother-looking, radiant appearance when paired with suitable skincare products.

Enhancing Skincare Product Application

Cosmetic microneedling can support the even distribution of serums and skincare formulas across the skin’s surface. When combined with suitable cosmetic products, it can become part of a consistent skincare routine focused on hydration, texture, and overall skin appearance.

Depth and Speed Settings

Adjust the depth and speed settings of your Dr. Pen device based on the area being used, your personal comfort level, and device instructions.

Delicate areas, such as around the eyes, may require lower settings for better control. If you are new to cosmetic microneedling or using the device on sensitive areas, begin with lower speed settings and gradually adjust according to your experience.

Most Dr. Pen devices offer adjustable speed settings from 1 to 5. Lower speeds may provide greater control for delicate areas, while higher speeds may be suitable for larger surface areas depending on device guidance and personal preference.

Important: Always use a new, sealed cartridge for each session to support hygiene and maintain product quality.

To support skin comfort and maintain your skincare routine:

• Apply sunscreen (SPF) daily.
• Keep skin moisturized with suitable skincare products.
