Become a poster child for bright skin

Gone are the days of the 'trial and error' process and feeling the need to constantly hide your skin behind heavy makeup.

We’ve created a concentrated serum that's calibrated for you to meet your specific skin needs. And now with the right products within your grasp, we can guarantee only brighter skin days ahead.

Our research reveals...

Why most anti-pigmentation serums don’t work on your melanin-rich skin.

Most brightening serums are either too strong and will trigger excess melanin production, causing more hyperpigmentation.

Or, they use the single-star ingredient approach, which may work on lighter skin, but not on your melanin-rich skin.

Treating hyperpigmentation in melanin-rich skin requires both a gentle, yet multi-tiered approach to ensure that all avenues for producing excess melanin are addressed.

We’re all about your melanin

The unique functions and structure of your melanin-rich skin are at the heart of our scientific process. You are the star of our show.

We’re scientifically led

 Our team of skin chemists use their two decades of experience creating prescriptive skincare to make natural brightening blends just for you.

We’re custom-made

You shouldn't have to settle for ‘one size fits all!’ Whether you’re a phototype IV, V or VI, we'll create a serum that fits your skin type, and your level of hyperpigmentation.

Cruelty and harm free

We're committed to using only the highest standard of biodynamic ingredients, and of course, we do not test on animals.

No endocrine disruptors

Endocrine disruptors like phenoxyethanol can negatively affect your hormonal health and your fertility. So that's a 'no' from us. 

Sustainably-sourced

We always prioritize environmentally responsible ingredients that respect the integrity of your skin, your health, and the planet.

80% of our customers reported a more uniform, healthier, brighter skin after using our Sevenly Delight Brightening serum.

This is thanks to a gentle (but powerful) synergy of:

  • biodynamic active ingredients that help balance pigmentation, while preventing and fading hyperpigmentation 
  • seven brightening active ingredients that tackle excess melanin production through seven melanin pathways 
  • antioxidants that scavenge free-radicals that may cause inflammation, and therefore trigger hyperpigmentation
  • a combination of gentle  chemicals and enzymatic exfoliators that will maintain healthy cell renewal
  • soothing agents that keep hyperpigmentation-triggering inflammation at bay
  • moisturizers, humectants, and emollients to keep your skin nourished and hydrated 

How is your Sevenly Delight Brightening Serum made?

First, our skin chemists 
create a core blend.

What's in the core blend?

Key active ingredients:

Vitalized Water, Radish Root Extract, Almond Oil, and Royal Jelly:
 Emollients and humectants that deeply nourish the skin.

Vitamin C, Vitamin B6, Astaxanthin, Cichorium Root Extract: Vitamins and antioxidants with powerful skin brightening effects. 

Lilium Candidum Extract: Prevents and reduces brown spots, skin blemishes, and hyperpigmentation, along with increasing cell regeneration.

Niacinamide: Reduces inflammatory response, while reducing post-acne scars and dark spots.

Azelaic Acid: Blocks the main process in the formation of hyperpigmentation, unifies the complexion, and exfoliates the skin for a radiant glow. 

Salicylic Acid, Citric Acid, Lactic Acid: AHA's and BHA's that slough away dead skin cells, brighten an uneven complexion, and gently treat acne breakouts.

Then, they boost the core blend with the below actives for a maximized brightening effect.

We add various concentrations and combinations of brightening ingredients (and more) in the core blends to customize each serum to your melanin levels, skin type, and specific skin concerns.

"I've been using this for 4 weeks now, and I'm really loving it.
It says my name on it, and it feels like 4.5.6 is catering to my skin! 🙌🏽 Darker skin needs a strong, yet gentle blend of ingredients to clear hyperpigmentation that settles below the skin—and the traditional skincare industry doesn't make them strong enough for darker tones.⁠ ⁠Using the right serum for your skin type is a game-changer."
Auri, phototype V

Along with getting a facial one every two months, that and using 4.5.6 has been a saviour. Thank you for making skincare for melanin skin also, nice to have been thought of.

BizzyBee

Since I have started using this product, my dark spots have begun to fade and skin tone has begun to even out. I’m so happy I invested in my skin, and am even happier there is a product out there for my skin type. Thank you so much.

 Crystal Waugh

I have used so many brands using Space NK. My big sister, a cosmetic, skin care consultant, taught me the importance of face creams. Now I can tell her about these brilliant product, 4.5.6. My skin has never looked this great. 

 Ms Ratbag

The initial couple weeks, my skin had a few breakouts, but I was warned that this may happen. My skin is now much brighter and the excessive oil that had been a problem is slowly but surely reducing.

 Aya Shili

I have been using the set for just under a month and have noticed a significant change in my glow and surface of my skin. I no longer have really oily skin, first thing in the morning like I used to, instead I wake up to a natural glow.

Jesika

Absolutely love these products and will certainly be repurchasing. I’ve also seen a difference in my skin using each product, especially the cleansing gel and the clear to be exfoliating mask. My skin loves it.
