Compatibility |
When to Use |
Notes |
| h2Peptide Serum |
✔️ Excellent |
AM & PM |
Apply Vitamin C first, allow absorption, then layer peptides to hydrate and firm. The combo supports collagen and skin resilience. |
| Hyaluronic Acid Serum |
✔️ Excellent |
AM & PM |
HA acts as a humectant base, Vitamin C brightens and protects. Use HA first, then layer Vitamin C for maximum benefit. |
| Bakuchiol Oil |
✔️ Compatible |
PM |
Use Vitamin C serum in the morning and Bakuchiol Oil at night for antioxidant and pro-collagen benefits without irritation. |
| Chemical Exfoliants (AHA/BHA) |
✔️ With Care |
PM (2–3x/week) |
If using exfoliants, wait 10 minutes before applying Vitamin C serum. Helps prevent overstimulation and keeps the skin balanced. |
| Retinol / Retinoids |
⚠️ Alternate Use |
PM (alternate nights) |
Don’t layer directly with retinoids. Alternate usage to avoid irritation and dryness. |
| Moisturizers |
✔️ Excellent |
AM & PM |
Apply Vitamin C serum before moisturizer for best penetration. Moisturizer seals in hydration and antioxidants. |
| SPF |
✔️ Required |
AM (last step) |
Vitamin C boosts UV defense but does not replace sunscreen. Always apply SPF as the final step in your morning routine. |
⚠️ A Note on Advanced Use
Some advanced users choose to layer Vitamin C, h2Peptide Serum, and exfoliating acids carefully in the same routine. While effective, this can increase the risk of irritation.
If you try this approach, start slow and use this order:
- Apply Vitamin C serum first (thin, water-based layer)
- Wait 10–15 minutes
- Follow with h2Peptide Serum
- Seal with moisturizer (and SPF in AM)
This combination may maximize brightening, antioxidant defense, and hydration — but it is not necessary for everyone. Always monitor your skin and adjust as needed.
