Yes, you absolutely can use PHAs with Hyaluronic Acid. They pair brilliantly together for skin hydration and exfoliation.
Polyhydroxy Acids (PHAs) are a gentle type of chemical exfoliant that helps to remove dead skin cells, revealing a smoother, brighter complexion. Unlike some stronger acids, their larger molecular size allows them to penetrate the skin more slowly, making them less irritating, especially for sensitive skin types.
Hyaluronic Acid (HA) is a powerful humectant, meaning it draws moisture from the air and deeper skin layers into the skin's surface. It's known for its ability to hold many times its weight in water, providing significant hydration and plumping effects.
Why PHA and Hyaluronic Acid are a Great Pairing
As stated in the reference, like other acids, PHAs pair brilliantly with other moisturizing ingredients, including hyaluronic acid and glycerin. This combination works well because PHAs, while exfoliating, can sometimes lead to a feeling of dryness, especially during the initial stages of use or if your skin is prone to dehydration. Hyaluronic Acid directly addresses this by replenishing moisture levels.
Here's a breakdown of the benefits:
- Enhanced Hydration: HA counteracts any potential dryness from the PHA exfoliation by providing intense hydration.
- Gentle Exfoliation: PHAs gently remove dead skin cells, improving texture and radiance without significant irritation.
- Improved Skin Barrier: Maintaining hydration with HA can help support the skin barrier function, which is crucial after exfoliation.
- Smoother, Plumper Skin: The combination leaves the skin looking smoother, more radiant, and visibly plumper.
The American Academy of Dermatology (AAD) recommends always following exfoliation with moisturization, and using a gentle moisturizer is key. Hyaluronic Acid serums or moisturizers are excellent choices for this step after using a PHA product.
How to Incorporate Them into Your Routine
You can typically use PHA products (like toners, serums, or cleansers) followed by a Hyaluronic Acid serum or moisturizer.
| Step | Product Type | Key Benefit | Notes |
|---|---|---|---|
| Exfoliation | PHA Product | Gentle exfoliation | Use as directed (e.g., serum, toner) |
| Hydration/Finish | Hyaluronic Acid | Intense hydration | Apply after PHA, followed by moisturizer |
Remember to introduce new products slowly and observe how your skin reacts. Always follow up with sun protection in the morning, especially when using exfoliants.
