What you get: A high-strength brightening serum powered by 15% Vitamin C & EGF. Targets hyperpigmentation, evens skin tone, and revives dull, tired skin for a visibly brighter, more even complexion.

Why it works: Driven by 15% Ascorbyl Glucoside-a stable, antioxidant-packed form of Vitamin C that helps defend against daily environmental damage while visibly brightening skin. Plant-derived EGF peptides work to support skin regeneration, improving elasticity and firmness over time.

How it feels: Lightweight, fast-absorbing, zero stickiness.

When to use: AM & PM. Use this 15% Vitamin C serum after cleansing.

Suitable for:

All skin types
Sensitive skin
Pregnancy & breastfeeding

Targets:

Hyperpigmentation
Dull Skin
Uneven skin tone

How to Use

Can be used in the AM and PM, but recommend in the AM. Antioxidants protect skin against daytime aggressors (UV, pollution and environmental stress), so you'd get more out of this egf serum if used in the morning.

On damp, cleansed skin, apply a pea-sized amount to face and neck. Gently pat in.

Follow with

Treatments → moisturiser.

Finish with SPF in your AM routine.

INKEY Tip

Layer serums thinnest to thickest. Wait 60 seconds between layers to avoid pilling.

Heads up

Don’t mix with Retinol, AHAs, BHAs or PHAs in the same routine. Use Vitamin C in the AM, Retinol or Acids in the PM.When adding new products to your skincare routine, we always recommend patch testing. Learn more here.

FAQs

HOW OFTEN CAN I USE IT? Once a day, AM. Always follow with SPF.

CAN I USE IT AT NIGHT? You can, but it works best in the morning to fight daily environmental damage.

CAN I LAYER IT WITH OTHER ACTIVES? Don’t layer with exfoliating acids (AHAs, BHAs) or Retinol in the same routine. Alternate: Vitamin C in the AM, Retinol or acids in the PM. Learn how to layer skincare.

CAN I USE IT WITH NIACINAMIDE? Yes - safe to layer with Niacinamide. But don’t mix with pure L-Ascorbic Acid.

DO I NEED TO WAIT BEFORE APPLYING OTHER PRODUCTS? If layering, give it 10 minutes before applying your next product to let EGF do its job.

IS IT SUITABLE FOR SENSITIVE SKIN? Yes - it’s a gentler Vitamin C. But always patch test. Learn more here

WHAT’S THE % OF EGF? 1% EGF.

Love it
Good and hydrating Vitamin C, soft for my sensitive skin and does the job well. I'm on my second bottle. Hoping there might be a sligthly stronger one with the tetrahexyldecyl in it!

Nice Formula, Mild Results
I tried this 15% vitamin C serum and, while it didn’t make a big difference on my skin, I did notice a slight brightening effect. It feels nice to apply and absorbs well, but the results weren’t as noticeable as I expected.
