How to use them
Alternate nights, for example Exosomes on Monday, Wednesday and Friday and Salicylic Acid on Tuesday and Thursday, with a plain moisturiser night in between if your skin feels sensitive. If your skin is resilient and already used to both, you can try layering them: apply Salicylic Acid first, wait a few minutes, then apply Exosomes.

What Exosomes does
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.

Frequently asked questions
Can I use Exosomes and Salicylic Acid together?
Yes, but not at the same time. 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.
Which goes first, Exosomes or Salicylic Acid?
Apply Salicylic Acid first, then Exosomes. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
Should I use Exosomes in the morning or at night?
Exosomes: works morning or night. If using a topical exosome serum, apply after cleansing and before heavier creams. For in-clinic exosome treatments, use only a qualified, licensed practitioner and ask what the exosomes are derived from.
Should I use Salicylic Acid in the morning or at night?
Salicylic Acid: works morning or night. Use as a cleanser daily or a leave-on 2% serum 3–4 times a week. It can dry out skin, so moisturise well.
Is Exosomes with Salicylic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Exosomes and Salicylic Acid. Check with your doctor.
