Hyaluronic Acid Serum
Serenvit Hyaluronic Acid Serum is BIOSAR's foundational hydrating serum for every skin type. Multi-weight Hyaluronic Acid binds moisture at multiple skin depths so the surface plumps without sitting heavy; Glycerin reinforces the comfort layer; Panthenol soothes any tightness left from cleansing. Use it morning and night before moisturizer and sunscreen as the universal hydration step that every routine benefits from. The texture is fluid and layers cleanly with any other serum. Tolerance-tested under dermatological supervision. Pairs with any Acnemed, Hydraderm, Sensimed, or Serenity Age cream.

Why it works
Thirsty skin drinks it in. BIOSAR's 8D Hyaluronic Acid floods every layer with deep, plumping moisture while Sodium PCA and Panthenol bind and hold hydration on a hydration-rich Aloe Vera base. Dryness disappears, fine dry lines soften, and skin looks deeply quenched, bouncy and dewy — with visible plumpness in as little as one to two weeks.

Proven Benefits
What this product does for your skin
Plumped surface
Multi-weight Hyaluronic Acid plumps the surface without sitting heavy.
Multi-depth hydration
Moisture binds at multiple skin depths for every skin type.
Eased tightness
Panthenol soothes any tightness left from cleansing.
Layers cleanly
The universal hydration step pairs with any serum.
How this formula works
The drink of water your skin has been thirsty for all day
Hyaluronic Acid pulls moisture deep into the surface while Sodium PCA helps hold it there, so hydration feels layered rather than fleeting. Panthenol soothes and softens as the water settles in, and the Aloe Vera base adds a final note of fresh comfort. It is pure hydration built as complementary layers, one plumping, quenching drop that leaves skin looking bouncy and dew-fresh.
Ingredient Research
Active ingredients backed by published studies
- 8 weeks
Eye-area hydration up, wrinkle depth down vs baseline
In 33 women, a low-molecular nano-hyaluronic acid lotion, serum and cream used for 8 weeks raised eye-area hydration by up to 96% and reduced wrinkle depth by up to 40% against baseline. Best-case figures; no control group.

Better hydration and less water loss than the vehicle
A double-blind, placebo-controlled study in adult volunteers: after 7 days, skin treated with dexpanthenol was better hydrated and lost less water than skin treated with the vehicle alone. The abstract reports no effect sizes.

Aloe extract raised skin water content vs its vehicle
In 20 women, creams with freeze-dried aloe vera extract raised the water content of the outer skin layer on the forearm versus the same cream without it, after two weeks of daily use. Water loss through the skin did not change.

What's inside — and what's not
- 01
Hyaluronic Acid
Sodium Hyaluronate
Humectant that binds many times its weight in water — one of the most effective hydrators available for topical use. BIOSAR formulates it as 8D Hyaluronic Acid: eight molecular weights working together, from higher weights that hold water and plump the surface to lower weights that carry hydration into the deeper stratum corneum, so one layer hydrates at several depths at once.
- 02
Panthenol
Panthenol (Provitamin B5)
Provitamin B5 that supports the skin's repair and hydration signals. Widely used in sensitive, post-procedure, and daily-care formulas.
- 03
Aloe Vera
Aloe Barbadensis Leaf Juice
Botanical humectant used as a comforting base across serums, baby care, and cleansers. High concentrations deliver noticeable cooling and hydration.
- 04
Sodium PCA
As a humectant it attracts ambient water and binds it within the surface layer, supporting suppleness.
