How to use a PDRN serum or ampoule: a simple routine
PDRN is one of the easiest actives to add to a routine. Here is exactly where it goes, what to pair it with, and how to use it in Indian heat and humidity.
By the MUMUKI India team · Updated 4 November 2026
Apply a PDRN serum or ampoule after cleansing (and toner, if you use one), then follow with moisturiser, and sunscreen in the morning. It can be used morning and night. Start with once a day if your skin is sensitive, and give it 4 to 8 weeks.
Where PDRN goes in your routine
- Cleanse with a gentle face wash and lukewarm water.
- Toner or a prep step (optional). MUMUKI's Bubble Mask is a leave-on prep step that melts in within seconds.
- PDRN serum or ampoule. Massage a small amount into face and neck until absorbed.
- Moisturiser to seal it in, such as a ceramide cream.
- Morning only: sunscreen, SPF 30 or higher.
A simple morning and night routine
| Morning | Night | |
|---|---|---|
| 1 | Gentle cleanse | Cleanse (double cleanse if you wore sunscreen or makeup) |

What to mix PDRN with
| Ingredient | With PDRN? | How |
|---|---|---|
| Hyaluronic acid, ceramides, panthenol | Yes, ideal | Same routine; many PDRN products already contain them |
| Niacinamide | Yes | Same routine, serum first then PDRN, or alternate mornings |
| Vitamin C | Yes | Vitamin C in the morning, PDRN at night if your skin is sensitive |
| Retinol or retinoids | Yes, carefully | Retinol at night, PDRN in the morning or on rest nights |
| AHA/BHA exfoliants, peels | Yes, on different nights | Do not stack strong acids with a new product while your skin adjusts |
How much to use
For an ampoule, 2 to 3 drops cover the face and neck. Thick, stretchy ampoules, like MUMUKI's Capsule Ampoule, spread further than they look. More product does not work faster.
Using it in Indian weather
- Humid summer and monsoon: serum plus a light gel moisturiser, or a mist, is often enough.
- Dry winter and AC rooms: add a richer cream at night; a cream mist helps during the day.
- After sun: PDRN products are soothing, but sunscreen is what prevents more tan.

Mistakes to avoid
- Skipping sunscreen in the morning.
- Starting several new actives in the same week; add one at a time.
- Judging after a few days. Give it 4 to 8 weeks.
- Using it on broken or infected skin.
Frequently asked questions
Can I use PDRN serum every day?
Yes. Most PDRN serums are gentle enough for daily use, morning and night. Start once a day if your skin is sensitive.
Should PDRN go before or after vitamin C?
If you use both in one routine, apply the thinner, watery product first. Many people keep vitamin C for the morning and PDRN for the night.
Can I use PDRN with retinol?
Yes. Use retinol at night and PDRN in the morning, or use PDRN on nights you skip retinol, to help skin feel more comfortable.
Do I still need sunscreen?
Yes, every morning. Sunscreen protects the results of any routine.
