Skincare trends come and go, but in recent years, there has been a clear shift toward minimalist routines, gentle formulations, and products designed for sensitive skin. Consumers are slowly turning away from overly harsh actives and complicated 10-step routines, instead embracing calming, supportive ingredients that strengthen the skin barrier. In this landscape, the The Outset Serum—formally known as the Firming Vegan Collagen Prep Serum—has emerged as one of the most talked-about essentials.
Created by The Outset, the clean, minimalist skincare line co-founded by Scarlett Johansson, the serum has become a flagship product thanks to its gentle, hydrating formula and universal appeal. Designed to prep the skin for the rest of your routine, it bridges the gap between hydration, anti-aging, and barrier support—without irritation.
A Philosophy Centered on Simplicity and Sensitivity
Before diving into the details of the serum itself, it’s helpful to understand the ethos behind The Outset. The brand was developed with the belief that skincare should be effective yet uncomplicated, and that barrier-friendly formulas should be accessible to all skin types—including those who are easily irritated by fragrance, acids, or overloaded routines.
The Outset positions its products as “basics that aren’t boring”—elegant, clean formulations that deliver real results through consistency and skin health, not aggressive actives. The serum, in particular, embodies this philosophy.
What Exactly Is The Outset Firming Vegan Collagen Prep Serum?
The The Outset Serum is a lightweight, gel-based serum designed to:
It is meant to be used immediately after cleansing and before moisturizer or sunscreen, functioning as a foundational layer that boosts the entire routine.
Unlike many “anti-aging” serums that rely heavily on retinol, AHAs, or vitamin C—ingredients that can be transformative but also irritating—the Outset Serum uses gentle, barrier-supporting ingredients that offer cumulative, long-term benefits.
Key Ingredients and Their Benefits
The serum’s formula is built around several standout ingredients that work synergistically to support hydration, firmness, and overall skin health.
Traditional collagen is derived from animal sources, but the Outset uses plant-based vegan collagen, a botanical alternative that mimics the plumping and firming effects of natural collagen. While topical collagen does not penetrate deeply enough to rebuild collagen structures, it does:
-
Improve surface smoothness
-
Enhance moisture retention
-
Strengthen the skin’s feel and texture
-
Give an instant plumping effect
It’s a gentle option for users who want firming benefits without sensitivities triggered by retinoids.
2. Hyaluroset™ Complex
A signature feature of the brand is its Hyaluroset™ Complex—The Outset’s vegan alternative to hyaluronic acid. It functions similarly by drawing moisture into the skin and locking it in, but users with sensitivities to conventional hyaluronic acid often find this gentler.
Effects include:
3. Plant-Derived Peptides
Peptides are known for stimulating skin repair and encouraging the appearance of firmness. The serum includes gentle peptide sources that help refine the look of lines and support the youthful bounce of the skin.
Supporting ingredients offer protection from daily environmental stressors—pollution, UV exposure, and oxidative stress—which contribute to early aging.
5. Glycerin and Moisture-Binding Agents
These maintain hydration, soften the skin, and support the moisture barrier.
Texture, Feel, and Application Experience
One of the reasons this serum has become a favorite is how lightweight and comfortable it feels on the skin. It has a silky, gel-like consistency that absorbs quickly without stickiness, greasiness, or residue. This makes it especially suitable for:
Many users also report that it prevents pilling when layered under sunscreen—a major advantage in morning routines.
Why It Stands Out in a Crowded Skincare Market
With countless serums available today, the Outset Serum distinguishes itself through its unique blend of simplicity and functionality. Here’s what sets it apart:
1. Formulated for All Skin Types—Especially Sensitive Skin
Because it is fragrance-free, non-irritating, and free of harsh actives, it is ideal for people who often react to strong serums.
2. A “Prep Serum” That Boosts the Whole Routine
Its role is not just to hydrate, but to increase the effectiveness of moisturizers and treatments layered on top.
3. Suitable for Twice-Daily Use
Unlike potent actives that require careful scheduling, the Outset Serum can be used morning and night without side effects.
4. Works Well With Other Ingredients
It pairs seamlessly with:
This flexibility makes it an easy addition to existing routines.
5. A Clean Beauty Formula That Performs
Many “clean” products struggle with efficacy, but this serum offers noticeable improvements in hydration and plumpness even without intense active ingredients.
Real-World Results: What Users Typically Experience
Most users report the following benefits after consistent use:

After 2–4 weeks:
After 6–8 weeks:
