The Luminosity Liquid to ignite your complexion in 1 week.

Brighter, radiant, strengthened skin.

This daily serum is designed for superior brightening, without exfoliation. Supercharged with clinically proven 5% Mushroom Complex, 5% Niacinamide, 3% Tranexamic Acid, 2% Alpha Arbutin, and 6 Brighteners & Peptides, this formulation gives your complexion a lit-from-within look, while strengthening each layer for healthier skin from the inside-out.

Product information

The perfect brightening formula does exist – no exfoliation needed —and it's right here.

Combining ancient philosophy with modern-day clinical studies, we've developed the ultimate solution for those dreaming of luminous skin without the effects of exfoliants and reduced risk of irritation.

Supercharged with an adaptogenic star ingredient, our clinically proven 5% Mushroom Complex is a blend of Reishi and Shiitake Mushrooms, a combination that gives your skin a luminous brilliance from within, and simultaneously strengthens your skin in the long-term. Used in traditional medicine for thousands of years, this powerhouse duo was shown to increase hydration by 30%, firmness by over 40%, and cell turnover by 18.5%, while also reducing the appearance of fine lines by 35%.*

Our all-star line-up of Key Allies includes a potent formulation of 3% Tranexamic Acid, 2% Alpha Arbutin, and 5% Niacinamide, which is proven to gently reduce the size of age spots by 13% over 8 weeks.**

This formula is the perfect at-home-complement to professional skin discolouration treatments, such as chemical peels or non-ablative laser treatments.*** Even when skin is sensitised, our serum is the perfect way to strengthen and support your complexion. With its liquid-soft, smooth texture, this serum sinks easily into damp skin.

Directions of use:
After cleansing and misting or toning, apply 3 pumps to face and neck. Follow up with your favourite moisturiser.

Always use SPF as the final step in your routine.

key allies

Clinically proven 5% Mushroom Complex. A fermented blend of Reishi and Shiitake Mushroom Extracts which strengthens and restores the skin while providing adaptogenic benefits. Reishi soothes and strengthens the skin barrier while Shiitake Mushroom helps to effectively brighten the skin through its naturally occurring source of Kojic Acid.

5% Niacinamide. The active form of Niacin (also known as Vitamin B3 or Nicotinic Acid) is one of the more stable active ingredients in skincare, with a pH around neutral. Reduces the appearance of pores and fine lines, improves blemish marks, and fades uneven texture. It also improves skin barrier function and its ability to retain moisture.

3% Tranexamic Acid. A powerhouse ingredient that can help reduce discolouration, fade dark spots, and even irregular skin tones for visibly brighter, less dull skin over time. It can also accelerate skin barrier recovery.

2% Alpha Arbutin. A plant-derived extract that works deeply on the skin to help visibly brighten, while also providing antioxidant protection. Evens and brightens skin tone and reduces appearance of excess discolouration, like dark spots or marks.

Is the serum safe for use during pregnancy?

Always consult your doctor when using new products, especially during pregnancy.

How is this product different from your other brightening products?

Both our 20% and 35% Vitamin C serums offer brightening, firming, and antioxidant protection, while our Mandelic Pigmentation Corrector Night Serum offers optimal pigmentation correction and exfoliation. This new advanced brightening formula takes both the maximal levels of brightening and pigmentation correction of both formulas and puts them into one, but with reduced risk of irritation.

Is the serum vegan?

Yes, there are no animal derived ingredients used in the formula.

Can this be used to replace Vitamin C?

While this formula is great for brightening, it does not fully substitute Vitamin C, as our Vitamin C serums have superior antioxidant protection properties, firm skin & boost efficacy of SPF. Both can be used together for a supercharged treatment, as our waterless Vitamin C serums don’t have additional brighteners.

Why has the colour of the formula changed?

The colour of the formula might slightly change as time goes by. This is a known phenomenon which occurs due the potency of active ingredients, such as clinically proven 5% Mushroom Complex. The efficacy of the formula is not affected.

What products/ingredients can this product not be paired with?

This product is ideal for use with Molecular Barrier Recovery Cream Balm in order to help further support post-procedure or post-treatment recovery. Always consult with your doctor or dermatologist when using these products in your post-procedure regimens.

Our products containing AHAs, BHA, and/or Retinoids along with this product are also safe for use.

We care for your skin

We care for you and your skin. That's why we would like to bring to your attention the following important information about this formula.

All our products are dermatologically tested and formulated to minimise the risk of irritation. However, some ingredients and their combinations can be too potent for sensitive/sensitised skin and cause a reaction.

In some instances, you might experience a brief tingling sensation after application — often a sign that the active ingredients in the formula are working. If you experience redness or your skin feels sensitive hours after applying a product, we recommend you stop using it and check with your dermatologist.

Even when you can't see the sun, it doesn't mean that your skin is safe from UV (Ultraviolet) rays. Through rain or snow, clouds or partial sun, we recommend wearing SPF every day of the year, both inside and outside. Not only will it protect your skin from potential damage caused by UV rays, but it also helps to keep the integrity of our products intact.
