LHA: A Smarter Acid for Sensitive, Congested Skin

Gentle Exfoliation Without Barrier Disruption Chemical exfoliants are key to refining skin texture, but many formulas can be too aggressive—especially for those with skin inflammation or a compromised skin barrier *BACKLINK TO BLOG ON SKIN BARRIER*. If traditional AHAs or BHAs feel too harsh, Lipo Hydroxy Acid (LHA) offers a clinically backed alternative. With its slow-release, surface-level activity, LHA exfoliates without over-stripping—making it ideal for sensitive skin and breakout-prone conditions.

What Is LHA?

LHA is a derivative of salicylic acid with a unique lipophilic structure and a skin-friendly pH of around 5.5. This allows it to work more gradually and target congested areas precisely, with less potential for skin inflammation.

Unlike conventional acids that act quickly and broadly, LHA provides localized exfoliation—making it suitable for skin types that can't tolerate high-strength exfoliants.

How Does LHA Work?

As a keratolytic agent, LHA breaks down the bonds between dead skin cells, promoting gentle shedding and smoother surface texture. Its lipid-soluble nature allows it to penetrate sebum-rich areas and help clear clogged pores without triggering irritation.

LHA supports:

Gradual exfoliation with reduced skin inflammation
Sebum control in oily or acne-prone skin
pH-balanced exfoliation that protects the skin barrier

Begin with 2–3 applications per week, especially if you’re new to exfoliating acids Use after cleansing and before serums or moisturizers Follow with a broad-spectrum SPF during the day to protect your newly exfoliated skin Compatible with calming and hydrating ingredients like niacinamide, ceramides, and hyaluronic acid

Benefits of LHA for Skin

✔ Gently removes dead skin cells with minimal irritation

✔ Clears pores and helps prevent breakouts

✔ Improves uneven skin texture and tone

✔ Calms skin inflammation while supporting barrier repair

✔ Well-suited for those with sensitive skin *INSERT BLOG ON SKIN SENSITVITY*

Why Choose LHA Over Traditional Acids?

For skin prone to redness, flaking, or skin barrier sensitivity, LHA offers results without harshness. Its structure allows for targeted action that respects the skin’s natural defenses—making it a preferred option in dermatologist-formulated products for mild to moderate acne, rough texture, and dull tone.

Final Takeaway

LHA offers a gentle, targeted approach to chemical exfoliation—delivering smoother skin and refined pores without triggering skin inflammation or compromising the skin barrier. Its ability to remove dead skin cells without irritation makes it a smart, effective option for those seeking clearer skin with a minimal-risk profile.

Frequently Asked Questions

How is LHA different from salicylic acid? +

While both are beta hydroxy acids, LHA is more lipophilic (oil-loving) and has a higher pH, allowing for slower, more controlled exfoliation.

Is LHA good for sensitive skin? +

Yes. LHA is known for its low irritation potential, making it a great option for sensitive, reactive, or redness-prone skin types

Does LHA make skin more sensitive to the sun? +

Yes. Like all exfoliants, LHA can increase sun sensitivity. Always follow with broad-spectrum SPF during the day.

What concentration of LHA is effective? +

LHA is typically used in low concentrations (around 0.3%–1.5%) due to its potency.

Is LHA pregnancy-safe? +

LHA is a derivative of salicylic acid, which is generally advised with caution during pregnancy. Always check with a healthcare provider before using any exfoliant while pregnant or breastfeeding.
