Kosas Plump + Juicy Spray-On Serum — Vegan Collagen Face Mist, Hydrating & Firming Primer

Kosas Plump + Juicy is a spray-on, vegan collagen and probiotic serum that hydrates, helps visibly firm, and primes skin with fast-absorbing active ingredients.

Designed as a lightweight mist rather than a heavy cream, this serum layers over clean skin to deliver peptides, amino acids, hyaluronic acid, and probiotics in a formula that skips oils, waxes, and emulsifiers. Its atomized delivery lets actives penetrate quickly, restoring skin’s surface moisture and pH balance so other products perform better. Clinically tested ingredients in the formula are used to support improved moisture retention and a firmer-looking texture when used consistently.

How does the spray format change my routine?

Spray application replaces thicker serums and creams when you want a fast-absorbing boost. The mist evenly distributes lightweight actives across the face, so there’s minimal residue and no heavy layering. It’s especially helpful as a quick morning refresh or a hydrating step before makeup.

• Even, fine mist for uniform coverage
• Absorbs rapidly with no oily film
• Works as a primer under makeup or before moisturizer

What key ingredients are in the formula and what do they do?

The blend centers on vegan collagen plus peptides and amino acids to reinforce visible firmness, complemented by hyaluronic acid for immediate hydration. Probiotics help balance the skin’s surface, while the absence of oils and emulsifiers allows actives to sink in directly. Together these ingredients are selected to support a plumper-looking complexion.

• Vegan collagen and peptides for visible lifting support
• Hyaluronic acid for water retention and plumping effect
• Probiotics to help rebalance and soothe skin

When and how should I use it for best results?

Use the mist on freshly cleansed skin morning and night for consistent benefits; follow with your regular moisturizer and sunscreen during the day. Hold the bottle a few inches from your face and spray 2–3 pumps, then allow it to absorb before layering additional products. For extra hydration, reapply over makeup or between flights.

• Apply to clean skin, morning and evening
• Follow with moisturizer and SPF in daytime routine
• Reapply as needed for a hydration boost during the day

Is this product suitable for sensitive or combination skin?

The formula is crafted without fragrance, silicones, and common irritants, making it compatible with many sensitive and combination skin types. Its water-based, oil-free composition reduces the chance of pore-clogging and heavy buildup. Patch-test if you have highly reactive skin or are using prescription actives.

• Free of fragrance, parabens, sulfates, and phthalates
• Oil-free and lightweight for combination or oily skin
• Suitable for sensitive skin with prior patch testing

Who this is for: Kosas Plump + Juicy is tailored for anyone seeking a fast-absorbing, non-greasy hydration boost that layers easily into an existing skin routine. It’s a good fit for people who want peptide and hyaluronic-based plumping without heavy creams, those who prefer vegan and cruelty-free formulas, and users looking to prime skin for makeup while supporting visible firmness and moisture retention.
