The Golden Rule: Damp Skin + Moisturizer
Hyaluronic acid works like a sponge, drawing water into the skin. If your skin is bone-dry β or the air around you is very dry β it has less water to work with. That’s why the best way to use any HA serum is:
- Damp skinApply right after cleansing while skin is still slightly damp, or mist your face first.
- HA serumPress 1β2 pumps into your face and neck.
- Seal it inFollow with moisturizer to lock that hydration in place.
Pro tip: Flying or sitting in air-conditioning all day? Keep a facial mist in your bag and press a little extra serum over moisturizer at lunch for a quick refresh.
Your Morning Routine
- CleanseUse a gentle cleanser. Leave skin slightly damp or mist with water/toner.
- Vitamin C (optional)Apply first if you use it, and let it absorb.
- PCA SKIN HA SerumPress 1β2 pumps into face and neck.
- MoisturizerLock in hydration.
- SunscreenFinish with SPF β EltaMD UV Clear layers beautifully on top.

Tips by Skin Type
| Skin type | Best routine |
|---|---|
| Oily | HA + a light gel moisturizer for hydration without heaviness |
| Dry | HA on damp skin under a richer cream, morning and night |
| Combination | HA all over; rich cream on cheeks, light lotion on T-zone |
| Sensitive | Use HA as a calming step during irritation; keep routine short |
| Mature | Use twice daily for the most visible plumping |
Good to know: Too much HA on very dry skin in dry air, without moisturizer on top, can actually feel tight. Always seal it in.
