For those ready to take their results further, Twilight Renewal – Progressive combines the high-performance results of MASTER SWITCH with the intelligent recovery of TWILIGHT ZONE. Master Switch works to accelerate renewal and refine skin texture, while TWILIGHT ZONE supports on recovery nights, restoring hydration, maintaining balance and keeping skin calm and resilient. This is skincare with rhythm: knowing when to push, and when to restore. The result is skin that looks smoother, stronger and more luminous, without compromise.

MASTER SWITCH:
It’s about you:

If you are ready for more in your retinoid routine, MASTER SWITCH Progressive 5% HPR Retinoid Serum is designed to deliver next level, advanced results for smoother, brighter, healthier looking skin.

It’s about the right things:

  • 5% HPR Retinoid Complex - more than double HPR retinoid than our NEW BEGINNING serum to power up skin renewal and collagen production.
  • 4D Hyaluronic Acid delivers multi-level hydration to keep skin plump, firm and bouncy
  • Bakuchiol + Bisabolol, natural plant extracts to restore skin radiance and soothe the skin barrier
  • Tranexamic Acid to brighten and protect while supporting a more even skin tone

This all in one, multi benefit, advanced serum is designed for those who have already built tolerance to gentler retinoids (like NEW BEGINNING Gentle 2% Retinoid Serum) and are ready to take the next step in skin renewal. 

NEW! TWILIGHT ZONE:
It’s about you:

When the world slows down and silence settles in, our intelligent formula gets to work by reinforcing the skin's moisture barrier, helping it to retain what it needs and shed what it doesn't. 
The result? Skin that looks well-rested, feels velvety, and glows as if it had the best sleep of its life, even if you didn't.

It’s about the right things:

  • Bromelain and Papain: Natural fruit enzymes from papaya and pineapple gently exfoliate to refine skin texture, revealing a fresher, natural glow.
  • 4D Multi-Molecular Hyaluronic Complex: Dives deep across the skin's layers to replenish moisture from within, creating a dewy plumpness. 
  • Boswellia Serrata (Frankincense): Lends its ancient soothing power to help quiet the skin and reduce redness.
  • Opuntia Ficus-Indica ( Prickly Pear): Rich in antioxidants, vitamins and minerals to protect, soothe and hydrate. 

Suitable for all skin types. Dermatologically tested.

Targets:

Suitable for:

✓ All skin types

✓ Experienced retinoid users

Ingredients

MASTER SWITCH:
5% HPR (Hydroxypinacolone Retinoate) Retinoid Complex - a next-generation, bio-available, low-irritation form of vitamin A. It speeds up cell turnover and stimulates collagen and elastin production to soften fine lines and wrinkles, decongest skin and refine skin texture without the irritation often associated with retinoids.

4D Multi-Molecular Hyaluronic Acid Complex - delivers multi-level hydration to keep skin plump and bouncy

Bakuchiol - a gentle, plant-based retinol alternative, helps minimise hyperpigmentation and supports clear, balanced, glowing skin without compromising your skin barrier.

Bisobolol – potent antioxidant that promotes skin radiance and soothes the skin barrier

Tranexamic acid - to brighten and protect while supporting a more even skin tone

TWILIGHT ZONE:
Bromelian and Papain: Natural fruit enzymes from papaya and pineapple quietly gently exfoliates, to refine texture, revealing a fresher, natural glow.

4D  Multi-Molecular Hyaluronic Complex: Dives deep into the skin's layers to replenish moisture from within, creating a dewy plumpness. 

Boswellia Serrata (Frankincense): Lends its ancient soothing power to help quiet the skin and reduce redness.

How to Use

MASTER SWITCH: In the evening, lightly massage 1-2 pumps onto your cleansed face and neck avoiding the eye area. Allow to absorb and apply your favourite night-time moisturiser.
(If you like to use a toner after cleansing, avoid AHA/BHA toners and at night opt for a hydrating essence instead)

Even if you have used retinoids before, we recommend you build up to daily use gradually, using twice a week for the first 2 weeks, three times a week for a further 2-4 weeks, working up to every night if well tolerated. For many, using every other night sees effective results.

NEW! TWILIGHT ZONE: In the evening, after cleansing, smooth an even layer over your face and neck (we like to put on the back of our hands too!) and leave on to gently exfoliate, hydrate and calm skin.
No rinse. No fuss. Just apply, drift off, and let our refining serum work its magic whilst you sleep.
Use 2-3 times weekly (on days when you don't use one of our HPR retinoid serums) to refine skin texture and boost glow for refreshed looking skin by morning.
