How to Use Medik8 Crystal Retinal 3 Review — Is It Worth It?
- Cleanse and tone your skin first — serums absorb best into clean, slightly damp skin.
- Dispense 2-3 drops (or a pea-sized amount if using a pump) onto your fingertips.
- Warm the serum between your fingers for a few seconds to help it spread evenly.
- Press the serum onto your face in light patting motions rather than rubbing — start at the centre and work outward.
- Allow 30-60 seconds to absorb before applying the next product.
- Follow with moisturiser to lock the serum in, and SPF if using in the morning.
