Navigating the world of advanced skincare often feels like a chemistry experiment. As someone who has spent years refining a personal routine, I frequently get asked: can I use peptides with AHA and BHA? The short answer is yes, you can use them toge Nov 21, 2006 — Paula's Choice BHA is fine. But for body scars. You will still probably find you need a stronger AHA, 30%-40% range or higher for effective scar ther, but success lies in the strategy, timing, and understanding the specific chemistry of your chosen formulas.
Understanding the Chemistry: Peptides vs. Acids
Peptides are essentially short chains of amino acids that serve as the building blocks of proteins. They are valued for their ability to support skin texture and resilience. On the other hand, Alpha Hydroxy Acids (AHAs like glycolic or lactic acid) and Beta Hydroxy Acids (BHAs like salicylic acid) are chemical exfoliants designed to dissolve dead skin cells and clear out pores.
There is a long-standing debate regarding whether acids destabilize peptides. While some argue that the low pH of acids could potentially alter the integrity of certain peptide chains, many modern, well-formulated products—such as those from brands like Medik8—are engineered to be stable. Medik8's pept Yes, you CAN use the iconic 2% BHA Liquid Exfoliant with ide formulas can also be safely layered with AHA/BHA products, as these acids will not damage the efficacy of the peptide molecule when the formulation is balanced correctly.
Strategic Layering: How to Incorporate Both
If you are wondering if you could use these ingredients in the same routine, consider these personal best practices:
1. The Wait-Time Method: If you are concerned about pH sensitivity, apply your AHA or BHA exfoliant first and allow it to dry completely. Wait about 10–15 minutes before applying your peptide serum. This ensures the exfoliant has performed its function without interfering with the subsequent application.
2. Separate by Time of Day: To avoid any risk of over-exfoliation or sensitivity, many users prefer to use their BHA or AHA in the evening to exfoliate and renew, then reserve their peptide serums for the morning to provide support throughout the day. AHA/BHA acids can work overnight to exfoliate and renew, while peptides support daytime environmental protection.
3. The Exception (Copper Peptides): One specific nuance involves copper peptides. Mixing peptides especially copper peptides with retinol, AHA/BHA acids, or vitamin C requires strategic scheduling to avoid potential irritation or oxidation. It is generally not recommended to copper peptides with retinol and AHA/BHA simultaneously, as these potent ingredients are better utilized at different times to maximize their individual benefits.
