philosophy hope in a jar biome-balance glow facial serum is an ultra-lightweight prebiotic and enhanced hyaluronic acid serum that instantly hydrates, supports a balanced skin microbiome, and boosts radiance.

This lightweight serum combines biotechnology-derived prebiotics, enhanced forms of hyaluronic acid, and AA2G (a stable vitamin C derivative) to hydrate skin immediately while supporting longer-term barrier resilience. The formula is designed to layer under moisturizers or makeup and is free of phthalates, BHT, and phenoxyethanol. It targets surface texture and visible glow without heaviness, making it a practical daily step in any skincare routine.

How quickly does this serum deliver hydration?

You’ll notice surface hydration on contact thanks to enhanced hyaluronic acid that draws moisture into the upper skin layers for an instant smoothing effect. The formulation provides around-the-clock moisture retention when used consistently, helping skin look plumper and less dry throughout the day.

• Instant skin-surface hydration on application
• Enhanced hyaluronic acid for superior moisture binding
• Lightweight texture that layers easily under creams or makeup

What does the prebiotic ingredient do for my skin?

The serum’s prebiotic is produced through biotechnology and helps support a balanced, healthy skin microbiome rather than killing microbes. By encouraging a stable microbial environment, it can help skin appear more even and resilient to daily stressors when used regularly.

• Supports a balanced skin microbiome without harsh disruption
• Helps maintain a healthier surface environment for skin cells
• Complements other barrier-supporting ingredients in your routine

How does AA2G contribute to glow and texture?

AA2G is a stabilized form of vitamin C that assists in delivering antioxidant support and brightening benefits while being gentler than some pure vitamin C forms. In this serum it works alongside hydration and microbiome support to improve the appearance of radiance and skin texture over time when applied consistently.

• Stable vitamin C derivative for long-lasting activity
• Supports visible radiance and smoother-looking skin texture
• Formulated to be compatible with everyday use and layering

Will this serum work with my current skincare routine?

• Use daily morning and/or night after cleansing
• Layering-friendly: apply before moisturizers and sunscreens
• Suitable for combination routines and multiple actives
