Kosas Plump & Juicy Vegan Collagen Spray 3.38 oz — Hydrating Peptide Mist for Plumper Skin

Kosas Plump and Juicy Vegan Collagen Spray is a lightweight, spray-on on-serum that hydrates, soothes, and helps visibly plump skin using peptides, probiotics, and hyaluronic acid.

This fast-absorbing mist combines a concentrated blend of vegan collagen-supporting ingredients with pre- and postbiotic technology to deliver active molecules directly to the skin. Designed to replace heavy emulsions, the formula skips oils and waxes so actives sink in quickly, rebalancing skin pH and boosting moisture retention. Clinically tested components in the formula are shown to support improved hydration and a firmer feel after consistent use.

How does this spray work differently from a classic serum or moisturizer?

The Kosas on-serum is delivered as a fine mist so active ingredients bypass occlusive agents and penetrate immediately. Because it contains no heavy oils or emulsifiers, peptides, amino acids, and hyaluronic acid are more bioavailable and start working right away.

• Spray-on texture for even, lightweight coverage
• No oils, waxes, or emulsifiers—faster absorption
• Formulated to rebalance skin pH for better ingredient performance
• Designed to layer under moisturizer and SPF without pilling

What key ingredients are included and what do they target?

The formula pairs vegan collagen-supporting peptides with hyaluronic acid, amino acids, and probiotic-derived actives to support barrier health and hydration. Each component focuses on different aspects of skin feel and resilience rather than making medical claims.

• Peptides — support skin’s firmness and elasticity appearance
• Hyaluronic acid — attracts and holds surface moisture for plumping
• Amino acids — help replenish skin’s natural building blocks
• Probiotics/prebiotics — rebalance microbiome support for comfort

How do I use this spray in my daily routine for best results?

Use on clean skin morning and night as a hydration-first step. Mist evenly over face, allow a few seconds to absorb, then follow with moisturizer and SPF during daytime to lock in benefits.

• Apply to cleansed skin before cream or oil
• Use morning and evening for consistent hydration
• Layer under makeup; let dry briefly to avoid transfer
• Follow with sunscreen in the morning for protection

Kosas Plump and Juicy Vegan Collagen Spray is formulated without mineral oil, talc, silicones, fragrance, parabens, sulfates, or phthalates, and is vegan, cruelty-free, and gluten-free. The formula aims to support a healthier-feeling complexion with lightweight, fast-absorbing actives rather than masking skin with heavy textures.

Who this is for: ideal for anyone who prefers lightweight, non-greasy skincare and wants to boost surface hydration and the look of firmness without added oils or heavy creams. It suits normal, combination, and oily skin types, and is a practical layering step for those who wear sunscreen and makeup. If you have very dry skin, you can pair the spray with a richer cream afterward; if sensitivity is a concern, patch-test first to confirm tolerance of the active blend.
