The detail

Everything you need to know

Benefits

Calms active breakouts

Azelaic acid at 10%, one of the most researched actives for blemish-prone skin.

Fades post-blemish marks

Azelaic acid helps limit excess melanin, so old marks fade rather than lingering.

Keeps pores clear

Salicylic acid at 2% works inside the pore.

Regulates oil

Niacinamide and zinc PCA moderate oil production, so pores stay refined between breakouts.

Supports the barrier

Chamomile, oat kernel oil and aloe support the barrier while the acids work.

Ingredients

Aqua, Azelaic Acid, Glycyrrhiza Glabra Root Extract, Camellia Sinensis Leaf Extract, Lactobacillus Ferment Lysate,
Salicylic Acid, Niacinamide, Chamomilla Recutita Flower Extract, Pentylene Glycol, 1,2-Hexanediol, Zinc PCA, Avena Sativa Kernel Oil, Aloe Barbadensis Leaf Extract, Dimethyl Sulfone, Xanthan Gum, Leuconostoc/Radish Root Ferment Filtrate.

How to use

Apply one pump to clean, dry skin before moisturiser. A little goes a long way. Follow with broad-spectrum SPF30+ in the morning.

Results build with consistent use. Most people see fewer new breakouts between weeks 4 and 8, and marks fading by week 12.

Storage

The airless pump protects the actives and prevents oxidation, so no refrigeration is needed. Store at room temperature, away from direct sunlight and heat.

From Dr SCS
"A breakout is never just a breakout. There is the blockage itself, the redness around it, the barrier damage from whatever you used to attack it, and the mark it leaves behind, which for a lot of people outlasts the spot by months. Most serums pick one of those and ignore the rest. The Clarify Serum was formulated to work on all of them at once."

FAQs

Frequently asked questions

What is in the Clarify Serum?

10% azelaic acid with 2% salicylic acid and niacinamide, alongside liquorice root, green tea extract, chamomile, aloe vera, oat kernel oil, zinc PCA and a lactobacillus ferment lysate.

Azelaic acid works on blemishes, redness and post-blemish pigmentation. Salicylic acid is oil-soluble, which means it penetrates sebum and works inside the pore itself, loosening the mix of oil and dead cells that blocks it so the follicle can clear. Niacinamide supports barrier function and helps regulate oil production. Liquorice root and green tea contribute antioxidant activity and work on tone.

The remaining botanicals keep a formulation this active comfortable to use twice daily, which is what 93% of our trial participants reported over twelve weeks. The full ingredient list is on this page.

Is it suitable for sensitive, blemish-prone skin?

Yes. The full formulation has been dermatologically tested and confirmed suitable for sensitive skin, and 93% of participants in our twelve-week trial experienced no irritation, the highest tolerance figure across our three systems. If your skin is reactive, patch test on the inner forearm for twenty-four hours before first
use.

Can I layer other actives with the serum?

Yes, though there is no need to. Avoid
stacking additional exfoliating acids in the same routine, and always use
SPF30+ in the morning.

Do I need the capsules as well?

The serum works on its own. The capsules work on the gut-skin axis, the internal driver a topical cannot reach, and the two were formulated to work as one.

Used together over twelve weeks, 83% of participants reported significantly clearer skin and an even, balanced tone, 80% reported more refined pores, and 87% would recommend the system to someone with blemish-prone skin.
