REINE STYLE vs. Basic Firming Serums

Not every anti-aging serum takes a targeted approach to firmness, renewal and skin texture. Here is how REINE STYLE Firming Serum is positioned to stand apart.

REINE STYLE Basic Options
Core Actives EGF + NAD+ + Collagen Extract Often relies on one main anti-aging ingredient
Approach Targets firmness, renewal and the appearance of fine lines Often focuses on a single visible concern
Skin Concerns Loss of firmness, fine lines, dullness and uneven texture More general anti-aging claims
Texture Lightweight serum designed for comfortable daily application Can feel heavy, sticky or overly rich
Added Support EGF, NAD+ and Collagen-focused care in one formula Less targeted support across multiple skin concerns
Routine Fit Easy to incorporate into a daily skincare routine Some formulas can be harder to layer comfortably
Skin Types Designed for a wide range of skin types Not every formula is created with different skin needs in mind

Firmer Skin. Smoother Look. More Confidence.

REINE STYLE is made for skin that looks tired, less firm, or uneven and needs targeted daily care focused on renewal, hydration, and a youthful-looking appearance.

Firmer-Looking Skin

Fine Line Care

Smoother Skin Texture

Revitalized-Looking Glow

Targeted Firming. Daily Skin Renewal.

This formula is built to support firmer-looking skin while keeping your routine lightweight, comfortable, and easy to use every day.

EGF

Firming + Renewal Support

EGF-focused care helps support the appearance of smoother, firmer and more youthful-looking skin.

NAD+

Skin Renewal Support

NAD+ focused care supports a refreshed and revitalized-looking complexion as part of a daily skincare routine.

Collagen Extract

Smooth + Supple Appearance

Collagen Extract helps support the look of supple, smooth skin and a more youthful-looking complexion.

Hydration Support

Moisture + Skin Comfort

A lightweight serum texture helps keep skin feeling hydrated, comfortable and smooth without a heavy finish.

Why This Formula Stands Out

More Than A Basic Firming Serum

REINE STYLE brings EGF, NAD+ and Collagen Extract together in one targeted serum, supporting a more complete approach to firmness, renewal and skin texture.

Basic Serums

One Focus

Often centered around one primary anti-aging concern

REINE STYLE

Multi-Action

Supports firmness, renewal, smoothness and a youthful-looking glow
