What Is Capryloyl Salicylic Acid (LHA)? 🔬 (Full Definition)

Capryloyl Salicylic Acid is a lipophilic (oil-attracting) derivative of traditional Salicylic Acid (BHA). By adding a capryloyl chain, scientists made LHA:

  • 5x slower and more controlled
  • far less irritating
  • ideal for sensitive skin
  • powerful at exfoliating inside pores

LHA gently targets:

  • blackheads
  • whiteheads
  • tiny bumps (closed comedones)
  • rough or uneven texture
  • dull, congested areas

Think of LHA as the “soft-focus filter” version of BHA — same benefits, almost no sting.


Ingredient Category 🧪

  • Type: Oil-Soluble Beta Hydroxy Acid (BHA derivative)
  • Main Functions: Deep pore exfoliation, texture smoothing, acne prevention
  • Texture Forms: Serums, gels, toners, treatment essences
  • Best For: Oily, acne-prone, textured, combination & sensitive skin

Manufacturing & Sustainability 🌍

  • Created by chemically modifying Salicylic Acid with a capryloyl chain
  • Designed for controlled, slow penetration
  • Eco-safe and widely approved in dermocosmetic formulations

Scientific Breakdown 🧬 (How LHA Works)

LHA has multiple scientifically backed mechanisms:

  • Oil-Soluble Action: Penetrates pores to dissolve sebum & debris
  • Keratolytic Action: Removes dead skin buildup gently
  • Antibacterial Effect: Reduces acne-causing bacteria
  • Surface Refining: Smooths uneven, bumpy texture
  • Brightening: Reduces dullness, hyperpigmentation & uneven tone

Why LHA is special: It exfoliates precisely where needed without damaging surrounding skin — ideal for sensitive or compromised skin.


Stability & Compatibility Factors 🔒

  • Stable in low–mid pH formulations
  • Pairs perfectly with Niacinamide
  • Safe with hydrating + barrier-supporting actives
  • Avoid layering with AHAs/BHAs in the same routine
