Exosomes vs PHA
Both target texture. Here's how they differ, and whether you should pick one or use both.
| Exosomes | PHA | |
|---|---|---|
| Main job | Aging, barrier and texture | Texture, hydration and dullness |
| Typical strength | varies (plant- or stem-cell-derived) | 3% – 10% |
| Best time | AM/PM | AM/PM |
| Irritation | ||
| Best for | Normal, Dry, Combination And Sensitive | Sensitive, Dry And Normal |
| Pregnancy | Ask | Safe |
| Price in India | ₹2,000 – ₹8,000 | ₹600 – ₹2,000 |
The verdict
Both are similarly gentle. Choose based on your main goal: Exosomes for aging, barrier and texture, PHA for texture, hydration and dullness.
Using both? Use with caution Low-pH acids can break down peptides, and with copper they can also irritate. Use the acid at one time of day and the peptide at the other, or on alternate nights. How to layer them →
Exosomes in short
Tiny cell-signalling particles, most often derived from plant or stem-cell cultures for cosmetic use. In-clinic exosome treatments (injected or applied after microneedling) have more published evidence than the topical serums sold direct to consumers. Regulatory status varies by country, and topical evidence is still described as early and limited, so treat "regeneration" or anti-ageing claims with caution.
PHA in short
Polyhydroxy acids are the gentlest chemical exfoliants. They work only on the surface, hydrate at the same time, and are usually tolerated by sensitive and rosacea-prone skin.
