How to Introduce Any Active Without Irritation
Most skin irritation comes from adding too much, too fast. Actives such as acids, retinoids and brightening ingredients can be very effective, but your skin needs time to adjust.
The 2-week method
- Week 1: use the new product two or three nights a week, after cleansing and before moisturiser.
- Week 2: if your skin is calm, use it every other night.
- Week 3 onwards: increase only if you feel comfortable.
Patch test first
Apply a small amount to the side of the jaw or behind the ear for three to five days before using it on your face.
One active at a time
Give each new product at least four weeks before judging it, unless it causes irritation. Adding several actives at once makes it impossible to know what is helping or harming your skin.
Signs to stop
- Persistent burning or stinging
- Redness that does not settle
- Peeling, swelling or a rash
Protect your skin
Use sunscreen every morning. Actives can make skin more sensitive to the sun.

If irritation persists or you are pregnant or breastfeeding, speak to a healthcare professional before using strong actives.
