BHA and LHA for Clogged Pores and Fine Lines
คำถาม
I have issues with clogged pores and fine lines, and I'm in my 40s. Which ingredient should I use, Capryloyl Salicylic Acid (LHA) or Salicylic Acid (BHA)?
I need one product for daily use and one for a weekly treatment. Could you please provide formulations for both?

Addressing Clogged Pores and Fine Lines with BHA and LHA
For your concerns regarding clogged pores and fine lines in your 40s, both Salicylic Acid (BHA) and Capryloyl Salicylic Acid (LHA) can be beneficial, but they work slightly differently and have different properties.
Understanding BHA and LHA:
- Salicylic Acid (BHA): This is a well-known ingredient for treating acne and clogged pores. It is oil-soluble, allowing it to penetrate into pores to help dissolve sebum and debris. BHA is also an effective exfoliant, helping to shed dead skin cells. It typically works best at a lower, more acidic pH (around 2-3), which can sometimes cause irritation, although different forms exist to mitigate this.
- Capryloyl Salicylic Acid (LHA): LHA is a derivative of salicylic acid. It is generally considered gentler than BHA because it is larger and penetrates the skin more slowly. LHA also has a pH closer to the skin's natural pH (around 5.5). While it exfoliates and helps with clogged pores, it is also noted for its effectiveness in reducing the appearance of fine lines and wrinkles, potentially more so than some other hydroxy acids like Glycolic Acid.
Which to Choose for Your Needs?
Given your concerns about both clogged pores and fine lines, and considering skin sensitivity can increase with age, a combination or strategic use of both might be ideal.
- For Clogged Pores: Salicylic Acid (BHA) is typically more potent at dissolving the material clogging pores due to its oil solubility and lower pH efficacy.
- For Fine Lines & Gentler Exfoliation: Capryloyl Salicylic Acid (LHA) is particularly noted for its anti-aging benefits on fine lines and offers a gentler exfoliation option.
Recommendation for Daily and Weekly Use:
- Daily Product: A gentler option is usually preferred for daily use. Capryloyl Salicylic Acid (LHA) is an excellent choice due to its gentleness and benefits for fine lines. Alternatively, a gentler form of Salicylic Acid (BHA) like SalicSoft™ or Liquid Salicylic Acid could be used at a low concentration.
- Weekly Treatment: For a more targeted treatment for clogged pores, a product with Salicylic Acid (BHA) at a higher concentration (up to 2% for leave-on) could be used weekly. If your primary weekly goal is more intensive exfoliation and fine line reduction with a gentler touch than high-concentration BHA, a higher concentration of LHA could also be considered (though very high concentrations of LHA may require professional guidance).
Example Formulations:
Here are simple examples for a daily serum and a weekly treatment:
1. Daily Gentle LHA Serum (targeting fine lines and mild exfoliation)
- Water: q.s.
- Glycerin: 5%
- Vitamin B3 (Niacinamide): 3-5% (Helps with skin barrier, pores, and aging)
- Vitamin B5 (Panthenol): 2% (Soothing)
- Capryloyl Salicylic Acid (LHA) EZ™: 5-10% (Provides 1-2% active LHA)
- Pro Polymer: 0.5-1% (Thickener)
Phenoxyethanol: 0.5-1% (Preservative)
Method:* Combine water, Glycerin, Vitamin B3, Vitamin B5, Pro Polymer, and Phenoxyethanol. Mix or stir until a gel forms. Add Capryloyl Salicylic Acid (LHA) EZ™ and mix thoroughly until uniform.
2. Weekly BHA Treatment Serum (targeting clogged pores)
- Propylene Glycol or Butylene Glycol: 15%
- Salicylic Acid (BHA) powder: 1.5-2%
- Water: q.s.
- Glycerin: 5%
- Dipotassium Glycyrrhizate: 0.2% (Soothing)
- Hydroxyethylcellulose: 0.5-1% (Thickener)
Phenoxyethanol: 0.5-1% (Preservative)
Method:* Dissolve Salicylic Acid (BHA) powder completely in Propylene Glycol or Butylene Glycol. In a separate container, combine water, Glycerin, Dipotassium Glycyrrhizate, Hydroxyethylcellulose, and Phenoxyethanol. Mix until uniform. Add the dissolved BHA mixture to the water phase and mix well.
Remember to always patch test new formulations and start with lower concentrations if you have sensitive skin. Sun protection is crucial when using exfoliating acids.
