Skin science
Dull skin is old skin that has not left yet.
Dead surface cells cling on with bonds. They scatter light, trap oil in pores and make tone look uneven. Glycolic acid loosens those bonds.
Texture
Smoother by morning as dull cells shed evenly instead of in patches.
Tone
Pigmentation and sun spots fade as renewal speeds up; methyl undecenoyl leucinate evens the complexion.
Pores
Less build-up, less congestion, fewer breakouts.
Fine lines
Retinol-like Tripeptide-31, without the irritation.
Acid, then everything the acid takes
Renewal balanced with hydration, soothing and barrier support. Fragrance-free.
Renewal
4% glycolic acid
The smallest AHA. Loosens the bonds between dull surface cells, smoothing texture and brightening tone.
Nourishment
Prickly pear & argan oils
Lightweight, nutrient-rich oils that replenish lipids and prevent post-exfoliation tightness.
Hydration
Glycerin & propanediol
Draw water into the skin for immediate hydration and suppleness during exfoliation.
Firmness & calm
Peptide complex
Tripeptide-31, Tetrapeptide-6, Tetrapeptide-34 and Palmitoyl Pentapeptide-4 for renewal, repair, calm and collagen.
Brightening
Methyl undecenoyl leucinate
Helps improve uneven tone and restore a balanced complexion.
Soothing
Clary sage & vitamin E acetate
Calms visible redness and protects the barrier during resurfacing.
Full ingredient list
The renewal ritual
Evenings. Start with one or two nights a week and build up as your skin allows.
Cleanse
Clean, dry skin
Wait a minute after cleansing so the skin is dry, not damp.
Apply
A thin layer, face and neck
Avoid the eye area. A light tingle is normal; a sting is not.
Seal
Night Cream on top
Lipids and peptides finish the job while the surface renews. Sunscreen tomorrow.
Morning
Not a morning product. The Day Cream, with its UV filters, is part of this ritual the next day.
Evening
Cleanse, Ultra Clarifying, Night Cream. Skip the serum on renewal nights, or use it under the cream if skin feels dry.
The morning after
Noticeably smoother, clearer, brighter and more hydrated.
Weeks 2 to 4
Tone evens, congestion clears, pores look refined.
Ongoing
Keep the rhythm your skin tolerates. Renewal is a rhythm, not a race.
