LIGHTWEIGHT HYDRATION FOR DEHYDRATED SKIN

The Hyaluronic Acid Serum by Biba Los Angeles is a lightweight, non-comedogenic hydration serum designed to replenish dehydrated skin while supporting overall skin balance and barrier function. The formula delivers water-based hydration without heaviness, stickiness, or pore congestion, making it suitable even for oily and acne-prone skin types.

WHY DEHYDRATED SKIN NEEDS WATER, NOT MORE OIL

Dehydrated skin lacks water, not oil. Many oily or breakout-prone skin types become dehydrated from over-cleansing, over-exfoliation, harsh acne treatments, or environmental stress while still producing excess oil. In the treatment room, dehydration is one of the most overlooked causes of imbalance, irritation, and visible congestion. This formula was designed to deliver lightweight hydration support without overwhelming the skin or contributing to congestion.

HYDRATION THAT SUPPORTS LONG-TERM SKIN BALANCE

Formulated with hyaluronic acid and multiple hydration-supporting humectants, this serum helps attract and retain water within the skin to improve surface smoothness, comfort, and overall hydration balance. With continued use, skin appears more supple, balanced, and stable rather than temporarily coated or overly occluded. Hydration is not just about adding water -  it is about helping the skin maintain it. Learn more about why skin hydration matters and  about the role of Hyaluronic Acid in skincare  in our educational skincare articles.

DEVELOPED FOR SENSITIVE, ACNE-PRONE, AND OVER-EXFOLIATED SKIN

Not all hyaluronic acid serums perform the same. Many create temporary surface hydration without supporting long-term skin comfort or barrier function. This treatment-room-inspired formula was developed for dehydrated skin, oily but dehydrated skin, sensitive or reactive skin, acne-prone skin needing hydration without congestion, and over-exfoliated or compromised skin. For drier skin types, layer with  Onerta® Cream Barrier to help seal in hydration.

FAQS

IS THIS SERUM SUITABLE FOR ACNE-PRONE SKIN?

Yes. The lightweight, non-comedogenic formula was designed to provide hydration without heaviness or pore congestion, making it suitable for acne-prone and oily skin types.

CAN OILY SKIN STILL BE DEHYDRATED?

Yes. Oily skin can still lack water and become dehydrated, especially from harsh cleansers, over-exfoliation, or acne treatments. Dehydration and excess oil production often exist together.

CAN I USE THIS WITH ACTIVE INGREDIENTS?

Yes. This serum layers well with acne treatments, exfoliants, vitamin C, and retinoids to help support hydration balance and improve skin comfort during treatment routines.

Balanced skin often starts with consistent hydration support rather than heavier layers or over-corrective routines. Hyaluronic Acid serum is dsigned for consistent daily use without heaviness or layering fatigue.
