Overview of Plexaderm


Plexaderm is a cult favorite brand known for its Rapid Reduction eye serum that works in minutes to tighten and smooth the delicate under eye area.

It works by using silicate minerals derived from shale rock to form a temporary tightening layer on the skin.

When applied sparingly to clean skin, Plexaderm claims to visibly reduce eye bags and wrinkles for up to 10 hours.

Some other key features of Plexaderm Rapid Reduction Serum:

  • Lightweight, fast-drying serum texture
  • Temporary tightening and lifting effect
  • Results in as little as 10 minutes
  • No need to rinse off
  • Can be applied under makeup

While many users see dramatic before-and-after results, Plexaderm typically works best for mild to moderate under eye bags and wrinkles. The effects are temporary and results will fade without reapplication.

Key Differences Between Plexaderm and Peter Thomas Roth Eye Products

While both Plexaderm and PTR offer visible tightening and lifting benefits for the under eye area, there are some notable differences between these brands’ formulations.

  • Ingredients

Plexaderm relies primarily on silicate minerals derived from shale clay to tighten the skin temporarily. These minerals work on the skin’s surface, drawing water out and providing an immediate tightening effect.

Unlike some skincare products, Plexaderm doesn’t incorporate traditional ingredients like hydrators and emollients, which often nourish the skin.

PTR eye products take a different approach, incorporating a blend of elastin, polymers, and silicones to offer immediate tightening effects.

In addition to these, PTR eye creams often include hydrating and nourishing ingredients, aimed at improving the skin’s texture and overall health over time.

  • Product Form and Texture

Plexaderm stands out with its lightweight serum texture, allowing it to dry down quickly upon application. This feature is particularly beneficial for those seeking a fast-absorbing product, leaving no residue behind.

Conversely, the PTR eye cream sports a richer, creamy gel texture. This consistency lends itself to deeper hydration and nourishment, providing an enriching experience for the under-eye area.

  • Usage and Application

Designed for temporary, quick fixes, Plexaderm is applied sparingly under the eyes before makeup application. Its role is primarily to offer instant results, addressing issues like under-eye bags and wrinkles for the short term.

PTR eye cream, however, is crafted for consistent, twice-daily usage – morning and night. This regular application is aimed at continuously improving the eye area, addressing not just the immediate concerns but also working towards long-term skin health.

  • Immediate Effects vs Long Term Results

Plexaderm’s forte lies in its ability to deliver instant results. Upon application, users can expect a visible reduction in under-eye bags and wrinkles, with effects lasting up to 10 hours.

However, it’s crucial to note that Plexaderm does not treat the underlying skin issues, focusing on surface-level improvements.

PTR eye cream goes beyond immediate tightening. While it offers instant results, it also works progressively over weeks of use, improving the appearance of bags, wrinkles, and boosting elasticity for cumulative effects.

This dual-action approach addresses both immediate concerns and the long-term health of the under-eye area.

  • Side Effects and Safety

Given its quick-drying nature due to the silicate minerals, Plexaderm can occasionally cause irritation or redness, particularly for those with sensitive skin. This reaction arises as the minerals rapidly dry the skin to achieve the tightening effect.

In contrast, PTR eye cream is generally well-tolerated, with minimal side effects reported. Its formulation is balanced, combining tightening agents with nourishing ingredients, reducing the likelihood of irritation and promoting skin health.

  • Cost and Value

Plexaderm is more affordable on a per-ounce basis compared to PTR eye cream. However, it’s important to consider the longevity of results and the need for daily reapplication to maintain the effects, which could influence overall value.

While PTR eye cream comes with a higher price tag, it offers a dual benefit of immediate results and long-term improvements. The consistent application helps treat and enhance the skin over time, potentially offering better value for those seeking lasting benefits.
