LHA Serum

SkinCeuticals LHA Serum is a targeted, oil-free serum formulated for aging skin prone to breakouts. The first-to-market formula combines 2% dioic acid with an optimal alpha- and beta-hydroxy acid blend — including LHA, salicylic acid, glycolic acid, and citric acid — to simultaneously reduce the formation of acne and clogged pores while visibly improving the appearance of fine lines, wrinkles, and uneven skin tone. This dual-action approach makes it uniquely effective for oily and combination skin types that face the challenge of managing both active blemishes and visible signs of aging at the same time.

Unlike single-concern treatments that address either acne or aging in isolation, LHA Serum tackles both simultaneously — reducing excess sebum production, decongesting pores, and refining skin texture while smoothing fine lines and improving overall skin tone. Its oil-free, lightweight formula absorbs quickly without heaviness, making it an ideal daily serum for oily, combination, and aging skin prone to congestion. Available in a 15ml travel size and full-size 30ml.

Skin Types

Formulated for oily and combination skin types, including aging skin prone to breakouts. Particularly beneficial for those experiencing the dual challenge of active blemishes and visible signs of aging — a combination that standard acne or anti-aging treatments alone often fail to address effectively.

Key Ingredients

• 2% Dioic Acid — Naturally derived from vegetables, dioic acid is the cornerstone of this formula’s blemish-fighting action. It helps reduce excess sebum production at the source, addressing one of the primary drivers of acne formation in oily and combination skin. Its sebum-regulating properties also contribute to a less shiny, more balanced complexion over time.
• 0.3% LHA (Caproloyl Salicylic Acid) — A lipo-hydroxy acid and lipophilic derivative of salicylic acid that evenly exfoliates the skin’s surface, decongests pores, and refines skin texture. Its lipophilic nature allows it to penetrate the pore lining more effectively than standard salicylic acid, while its anti-bacterial and anti-inflammatory properties help address the underlying causes of blemishes without causing irritation.
• 1.5% Salicylic Acid — A beta-hydroxy acid (BHA) that is oil-soluble, allowing it to penetrate into the pore and dissolve the sebum and debris that cause congestion and breakouts. Salicylic acid refines the appearance of pores and helps reduce the formation of acne, working synergistically with LHA for enhanced pore-clearing action.
• 3.5% Glycolic Acid + 0.5% Citric Acid — A synergistic alpha-hydroxy acid (AHA) duo that works at the skin’s surface to smooth texture, minimize the appearance of fine lines and wrinkles, and improve overall skin tone. Glycolic acid accelerates cell turnover to reveal fresher, more radiant skin, while citric acid provides additional brightening and antioxidant support.

The Science Behind It

Adult acne and visible signs of aging often coexist in oily and combination skin types, yet most skincare treatments are designed to address only one concern at a time. Many traditional acne treatments rely on drying ingredients that can exacerbate the appearance of fine lines and wrinkles, while standard anti-aging serums may be too rich or occlusive for blemish-prone skin. LHA Serum was developed to bridge this gap — combining dioic acid’s sebum-regulating and anti-acne properties with a carefully calibrated multi-acid exfoliating complex that simultaneously targets the visible signs of aging. The result is a single, oil-free serum that delivers comprehensive correction for the unique needs of adult acne-prone skin.

How to Use

Apply four to five drops of LHA Serum to dry skin once or twice daily. In the morning, apply after cleansing and before moisturizer and sunscreen — broad-spectrum SPF is essential when using exfoliating acids, as they increase photosensitivity. In the evening, apply after cleansing as part of your corrective skincare routine. If introducing for the first time, begin with once-daily use and gradually increase frequency as tolerated.
