Good Molecules B5 Hydrating Body Serum 120 ml — Vitamin B5 (4%) + Beta-Glucan for Lightweight, Non-Greasy Hydration

Good Molecules B5 Hydrating Body Serum is a fast-absorbing, non-greasy body serum that delivers lasting hydration and plumping with 4% panthenol, beta-glucan, and polyglutamic acid.

Lightweight and silky, this 120 ml body serum was designed to replenish moisture across the body without leaving residue or staining clothing. Its water-gel texture sinks in quickly, supporting the skin’s barrier while helping skin look smoother and more hydrated. The formula is fragrance-free, vegan, and free from alcohol and oils, so it layers easily under lotions or works alone on damp or dry skin.

How does this serum hydrate dry, flaky skin?

The serum combines humectant and barrier-supporting ingredients to draw in and lock moisture. Panthenol (vitamin B5) at 4% helps support cells involved in barrier repair, while polyglutamic acid provides immediate surface hydration for a visibly plumper appearance. Beta-glucan soothes and contributes to longer-lasting moisture retention.

• 4% panthenol to encourage barrier resilience and moisture retention
• Polyglutamic acid for instant, surface-level hydration and plumpness
• Beta-glucan to calm redness and support sustained hydration
• Non-greasy gel texture absorbs quickly and layers under other products

Will this serum work for sensitive or reactive skin?

The formulation avoids fragrances and alcohols, reducing common irritants for sensitive skin. Beta-glucan is included for its skin-soothing properties, while the overall recipe focuses on gentle humectants rather than harsh actives. Patch testing is recommended if you have a history of strong sensitivities.

• Fragrance-free and vegan formulation minimizes irritation risk
• Soothing beta-glucan supports comfort on reactive skin
• Alcohol- and oil-free to reduce potential dryness or clogging
• Suitable for use on both dry and damp skin for flexible application

How do you incorporate the B5 Hydrating Body Serum into a routine?

Use it morning and/or night as your targeted body hydration step. Apply a generous layer to arms, legs, chest, or any dry areas, then follow with a heavier cream if you need extra occlusion. It can be applied after showering on damp skin to maximize moisture locking or on dry skin when needed throughout the day.

• Apply to clean skin—either damp after showering or dry between baths
• Massage into rough patches, elbows, knees, and bodywide for even hydration
• Layer under a thicker body cream at night for enhanced moisture retention
• Fast-drying texture makes it practical for daytime use without staining clothes

What results can you expect and how soon?

Immediate results typically include smoother-feeling skin and a hydrated, dewy look thanks to polyglutamic acid’s humectant action. With continued daily use, panthenol and beta-glucan aim to support barrier function, helping skin maintain moisture and reducing the appearance of dryness over time. Individual outcomes vary with skin type and baseline dryness.

• Instant: improved surface hydration and softer texture
• Short-term: reduced dryness and less visible roughness within days
• Long-term: supportive barrier improvement and ongoing moisture retention with regular use

Who is this for: Good Molecules B5 Hydrating Body Serum is ideal for anyone wanting weightless, effective body hydration—especially people with dry, dehydrated, or easily irritated skin who prefer fragrance-free, vegan formulas. It suits those who want a quick-absorbing layer that can be used alone or as a hydrating boost under body creams and oils.
