Copper Peptide (GHK-Cu) 2% Day Gel-Cream - lightweight daytime hydration that sits well under SPF, protecting your brightening results
No parabens · no mineral oil · no synthetic fragrance

Best for: dull, uneven-looking skin that wants a brighter, more radiant complexion - daily SPF is essential alongside this routine.

Set contents: 1x Brightening Serum, 1x Day Gel-Cream.

Key Benefits

Brightens - supports a brighter, more radiant-looking complexion
Evens tone - for a more even-looking skin tone and the look of dark spots
Antioxidant defence - glutathione and stable Vitamin C against daily environmental stress
All-day hydration - a lightweight gel-cream that sits well under SPF and makeup

What to expect: a fresher glow within 1-2 weeks; a more even-looking tone builds over 8-12 weeks (daily SPF essential).

How to Use

Use morning and evening. After cleansing, press 3-4 drops of the Glutathione 2% Brightening Serum onto clean skin across the face and neck, focusing on dark spots and uneven areas. Let it absorb for about a minute.

Morning: seal with the Copper Peptide (GHK-Cu) 2% Day Gel-Cream and always finish with SPF 30+.

Clinical Research

Clinical research suggests that topical glutathione (2% GSSG) can support a more even, radiant-looking complexion, including:

A significantly more even-looking skin tone versus placebo (p<0.001)
Improved radiance and smoothness
Antioxidant defence against environmental stress

Clinical research suggests that copper peptide (GHK-Cu) can support the appearance of firmer, healthier-looking skin, including:

A firmer, more elastic-looking skin
Improved firmness and elasticity
Reduced appearance of fine lines

Our serum uses 2% oxidized glutathione (GSSG) - the exact active studied in a double-blind, split-face clinical trial.

GHK-Cu is one of the most-studied peptides in skin science.

What is included in this set?

Two full-size products: the Glutathione 2% Brightening Serum (30ml) and the Copper Peptide (GHK-Cu) 2% Day Gel-Cream (50ml).

Why are these two paired?

Glutathione is an antioxidant that supports a brighter, more even-looking tone, and the lightweight Day Gel-Cream seals it in while sitting comfortably under SPF - which is what protects brightening results.

In which order do I use them?

Morning and evening: cleanse, then press 3-4 drops of the Glutathione Serum onto clean skin, focusing on dark spots and uneven areas. In the morning, follow with the Day Gel-Cream and SPF 30+.

Do I really need SPF with this set?

Yes. Daily broad-spectrum SPF 30+ is essential with any brightening routine - without it, UV exposure works against the more even tone you are building.

How long before I see a difference?

A fresher glow typically shows within 1-2 weeks; a more even-looking tone builds over 8-12 weeks, provided SPF is used every day.

Will this bleach my skin or remove pigmentation?

No. This is a cosmetic brightening routine that works on the look of tone and radiance. It does not bleach the skin and it does not treat pigmentation as a medical condition.
