The Ordinary Lactic Acid 10% + Hyaluronic Acid 2% exfoliating serum, 1 fl oz — gentle resurfacing & hydration

The Ordinary Lactic Acid 10% + Hyaluronic Acid 2% is a water-based, high-strength exfoliating serum that refines texture and brightens skin while supporting hydration.

This concentrated serum uses 10% lactic acid to remove dead surface cells and promote a smoother, more even-looking complexion. The formula pairs l‑acid with 2% hyaluronic acid for moisture support and includes Tasmanian pepperberry extract to help reduce the risk of irritation during use. With a pH around 3.8, the product is designed to balance acidity and active availability for effective surface exfoliation; it is particularly suited to drier skin types seeking gradual resurfacing without heavy oils.

How does this serum improve skin texture and tone?

The lactic acid in this serum is an alpha hydroxy acid that gently liberates dead skin cells from the surface, which can reduce rough patches and improve overall skin evenness. Over consistent use, texture appears smoother and skin reflects light more evenly, creating a brighter look.

• Contains 10% lactic acid for surface exfoliation.
• Supports visible smoothing of fine roughness and uneven tone.
• Water-based vehicle for a lightweight, non-greasy finish.

Will it dry out my skin, and how does hyaluronic acid help?

The serum combines exfoliation with 2% hyaluronic acid to attract and hold moisture, so skin feels hydrated rather than stripped. Because it’s water-based and free of oils and silicones, the formula layers well beneath heavier moisturizers to restore softness after exfoliation.

• 2% hyaluronic acid provides multi-depth hydration support.
• Suitable for layering under creams and oils for added moisture.
• Free from alcohol, oil, and silicone to reduce potential dryness.

How should I incorporate it into my routine for safe results?

Use this serum once daily in the evening, applying a few drops to clean, dry skin and following with your usual moisturizer. Because exfoliation increases light sensitivity, always apply broad-spectrum sunscreen during the day while using this product and for a week after stopping.

• Apply once per day, preferably at night, on dry, cleansed skin.
• Follow with moisturizer; reintroduce gradually if new to acids.
• Wear SPF daily to protect newly exfoliated skin cells.

Is the formula gentle enough for sensitive or dry skin?

The formula was created with dry skin in mind and contains Tasmanian pepperberry extract, included to help calm potential irritation. Still, those with sensitive or highly reactive skin should patch-test first and introduce the product slowly to monitor tolerance.

• Tasmanian pepperberry extract helps minimize irritation risk.
• pH ~3.8 aligns with lactic acid’s profile for effective action.
• Patch testing recommended for sensitive or reactive skin types.

Who this is for: This serum is aimed at people with dry to combination skin who want a reliable at-home resurfacing step to smooth texture, reduce dullness, and boost radiance. It suits users who are comfortable incorporating acids into their evening routine and who will use daily sun protection. Avoid combining with other strong acids or retinoids without professional guidance; if you have concerns, consult a dermatologist before beginning regular use.
