If you have spent any time lurking on skincare forums, you have likely encountered the heated debate regarding peptides and AHA Reddit threads.

I use glycolic acid and salicylic acid AM and peptides PM.Read more ith various topical applications to support skin texture and elasticity, I have spent years testing different routines. The core of the confusion usually stems from the idea that using AHA (Alpha Hydroxy Acids) and peptides together is the key to a perfect routine, while others warn that the low pH of acids might destabilize peptide chains.
Understanding the Chemistry
The primary concern often discussed is whether the acidity of AHAs, BHAs, or Vitamin C can degrade the molecular structure of peptides. Many users believe that it is not good to use peptide with AHAs because the acidic environment might render the proteins ineffective. However, I have found that there is no interaction between retinol and peptides in many modern formulations, and the same logic often applies to h I need a chemistry lesson!

In my experience, no, you can't use peptides with AHA, BHA, Vit C in the same routine if you are looking for maximum stability, but no, it's OK to use them separately.

The Role of Peptides in Daily Care
Peptides are essentially chains of amino acids that act as building blocks for proteins. Many people ask, "What are your favorite products with peptides?"

While some skeptics claim that peptides may help with aging, my observations suggest that consistency is the real secret.

Addressing the "Canceling Out" Myth
A common question I see is: "Is it cancelling out my peptides?" when someone adds an acid toner to their routine. The confusion is understandable, especially when brands like Ole Henriksen pair Vitamin C and AHA toners with peptide moisturizers.
The consensus among experienced enthusiasts is that if you are worried about efficacy, simply practice "skin cycling." Use your AHA on specific nights and focus on hydration and peptide serums on others. This ensures that the low pH of the acid doesn't potentially interfere with the peptides. Remember, peptides are like hydrating serums, eye creams and exfoliants—they are beneficial, but they don't necessarily need to be applied at the exact same second to provide value.
Final Thoughts on Routine Building
If you are looking for anti-aging and brightening effects, it is important to manage expectations.

While I love my Ordinary Multi-Peptide and HA serum for its simplicity and hydration, I view it as a long-term support tool rather than a quick fix.
Ultimately, if you are concerned about whether using retinol or AHAs at the same time as peptides reduces their efficacy, the safest bet is to separate them. By spacing out your application, you avoid the risk of irritation and ensure that every product you apply is working exactly as intended. Whether you are a beginner or a veteran, the goal is to keep the skin barrier happy, hydrated, and resilient.
