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.

WHAT DOES A HYALURONIC ACID SERUM DO FOR THE SKIN?
A hyaluronic acid serum acts as a humectant, attracting and binding water to the skin to improve hydration, smoothness, and overall comfort. This formula uses multiple molecular weights of hyaluronic acid to hydrate at different levels, while botanical extracts help support the skin, leaving it balanced and plump.

IS A HYALURONIC ACID SERUM SUITABLE FOR ALL SKIN TYPES?
Yes. It is lightweight, non-irritating, and suitable for all skin types, including dry, oily, sensitive, and acne-prone skin.

CAN I USE A HYALURONIC ACID SERUM IF I HAVE OILY OR ACNE-PRONE SKIN?
Yes. Oily and acne-prone skin still requires hydration. This serum delivers moisture without clogging pores or adding heaviness, helping maintain balance.

CAN I USE A HYALURONIC ACID SERUM WITH RETINOL, VITAMIN C, OR OTHER ACTIVES?
Yes. It layers well with active ingredients and helps reduce potential irritation by supporting hydration and the skin barrier.

CAN I USE A HYALURONIC ACID SERUM EVERY DAY?
Yes. It is designed for daily use, morning and evening, and integrates easily into any routine.

SHOULD I APPLY HYALURONIC ACID SERUM ON DRY OR DAMP SKIN?
Apply to slightly damp skin for best results. This helps bind water more effectively and improves hydration performance.

DO I NEED A MOISTURIZER AFTER HYALURONIC ACID SERUM?
Yes. The serum draws water into the skin, while a moisturizer helps seal in hydration and support the barrier.

WILL THIS HYALURONIC ACID SERUM FEEL STICKY OR HEAVY?
No. It has a lightweight, fast-absorbing texture that leaves skin smooth and hydrated without residue.

DOES A HYALURONIC ACID SERUM HELP WITH FINE LINES AND WRINKLES?
By improving hydration and skin plumpness, it can help soften the appearance of fine lines and support a smoother-looking complexion.

IS THIS HYALURONIC ACID SERUM SAFE FOR SENSITIVE SKIN?
Yes. It is designed to hydrate without irritation and is suitable for sensitive or reactive skin.

DOES THIS HYALURONIC ACID SERUM CONTAIN FRAGRANCE OR IRRITANTS?
No. It is free from added fragrance and common irritants, making it suitable for sensitive skin.

WHAT’S THE DIFFERENCE BETWEEN A HYALURONIC ACID SERUM AND A MOISTURIZER?
A serum delivers hydration into the skin, while a moisturizer helps lock that hydration in and protect the surface. Using both together provides optimal results.

IS HYALURONIC ACID SAFE TO USE DURING PREGNANCY?
Hyaluronic acid is generally considered safe. As with any skincare product, consult your healthcare provider if unsure.

HOW LONG DOES ONE BOTTLE LAST?
One bottle typically lasts 6–8 weeks with regular use (1–2 pumps, once or twice daily), depending on application and frequency.

HOW TO USE
