The goal is to achieve the best results without compromising the integrity of these delicate, high-performance compounds.

Understanding the Compatibility Challenge

When I first started using advanced skincare, I often fell into the trap of complicating skincare starting off with layering. I assumed that applying everything I owned would lead to faster results. However, I quickly discovered that using AHA and peptides together is the key—but only when done with a deep understanding of their chemical nature.

The primary concern is pH balance. Alpha hydroxy acid (AHA) products, such as glycolic acid or lactic acid, typically function at a low, acidic pH (around 3.5) to effectively exfoliate the skin. Conversely, many peptide formulas, particularly those focused on building collagen and elastin, are designed to sit at a more neutral pH (around 6.0). Using them together without buffer time can destabilize peptides, potentially rendering them less effective.

Expert Insights on Layering

I have found that Medik8's peptide formulas can also be safely layered with AHA/BHA products due to their specific stabilization technology. However, for most standard formulations, AHA's such as Salicylic Acid & Glycolic Acid can hinder the efficacy of peptides. Some experts suggest that these strong acids can potentially break the bonds in the amino acid chains that make up the peptide.

Therefore, using a peptide with an alpha hydroxy acid (AHA) should be managed by alternating your routine. I personally prefer to use my exfoliating acids in the evening and my peptide serums in the morning, or I allow at least 30 minutes of "buffer time" between Complicating skincare starting off with layeringbasics.

Synergistic Ingredients to Pair with Peptides

Practical Tips for Your Routine
