✓ Botanical AHAs + BHA in One Serum | ✓ Results Within a Couple of Days | ✓ iS Clinical's Most Popular Product

iS Clinical Active Serum is iS Clinical's most popular product: a fast-acting botanical serum that visibly evens skin tone, softens the look of fine lines and wrinkles and suits blemish-prone skin, all in one bottle. Described by physicians as remarkable and phenomenal according to the brand, it usually shows results within a couple of days and is suitable for all skin types and all ages, making it the exfoliating serum for clearer, smoother, brighter-looking skin.

iS Clinical Active Serum works through a blend of botanical AHAs and BHA: bilberry extract as a natural source of lactic acid, sugarcane extract as a source of glycolic acid and white willow bark as a source of salicylic acid, which together lift away dull surface cells, refine texture and deeply clean pores. Mushroom extract, a natural source of kojic acid, assists in brightening the overall complexion, while glycerin keeps the skin feeling moist and smooth rather than stripped. The signature cooling tingle on application is a sign of the potent activity at work, and it fades within moments.

Botanically sourced actives at effective levels, with glycerin so skin is left moist, not tight
Multi-tasking: lines, uneven tone, blemishes and pores are addressed in a single step
An award-winning formula the brand calls its bestseller, trusted in clinics worldwide
Suitable for all skin types and ages, including sensitive skin that starts slowly

Best For

Blemish-prone and congested skin
Fine lines, wrinkles and rough texture
Dark spots and uneven tone
Large or congested-looking pores
Anyone who wants one serum that does several jobs

Choose iS Clinical Active Serum if you want a single, fast-acting serum for clarity, tone and texture; if dark spots are your only concern, Brightening Serum is the more targeted option.

Becci, a registered aesthetics nurse with more than two decades in specialist skincare and medical aesthetics, is often asked which serum is worth buying first. Clients come to her for honest recommendations rather than a long list, and iS Clinical Active Serum is the one she suggests to anyone whose skin is doing several things at once, because it refines, brightens and clears without a drawer full of products.

FAQS

Is iS Clinical Active Serum good for blemish-prone skin? +

Yes - iS Clinical describes it as excellent for blemish-prone skin. The willow bark BHA exfoliates inside the pore, the AHAs from bilberry and sugarcane lift away dull surface cells, and mushroom extract helps brighten the marks blemishes leave behind, so it works on both the congestion and the aftermath.

Why does Active Serum tingle when I apply it? +

iS Clinical says potent activity will be noted on application as a cooling, tingling sensation. It comes from the botanical acids and a touch of menthol, and it fades within moments. If it feels too strong, mix a few drops with Hydra-Cool Serum or use it every other evening to start.

Can I use iS Clinical Active Serum with retinol? +

Yes, but not in the same application. Use Active Serum in the morning under sunscreen or on alternate evenings, and keep retinol to the other nights. Once your skin is comfortable with both, many people use Active Serum by day and retinol by night.

How quickly will I see results from Active Serum? +

iS Clinical says Active Serum usually produces results within a couple of days, with skin feeling smoother and looking clearer and brighter; it then continues to work on fine lines, tone and pores over the following weeks with consistent use.

What is the difference between Active Serum and Brightening Serum? +

They share the same botanical acid base of bilberry, sugarcane and willow bark. Active Serum is the all-rounder for blemishes, lines, tone and pores, while Brightening Serum adds alpha-arbutin and Norwegian kelp and is focused squarely on dark spots and uneven tone on the face and body.

Can I use Active Serum every day? +

Yes. iS Clinical says it can be used once or twice daily, and those with sensitive skin may start slowly and increase usage as tolerated. Always wear a broad-spectrum SPF in the morning.

Is Active Serum suitable for sensitive skin? +

iS Clinical formulates it for all skin types and all ages. Sensitive skin should begin every other evening, patch test first and consider buffering it with Hydra-Cool Serum until it settles.

Should I buy Active Serum in 15ml or 30ml? +

Both sizes are the same formula. The 15ml is ideal for trying Active Serum for the first time or for travel, while the 30ml is the better-value option once it has earned a permanent place in your routine. At 3-4 drops per application, a little goes a long way with either size.

Can I use iS Clinical Active Serum during pregnancy or while breastfeeding? +

iS Clinical states that its formulations are non-systemic and describes them as suitable during pregnancy and breastfeeding. Like most botanical acid serums, Active Serum is generally considered suitable, but check with your midwife or GP before adding any new active to your routine. iS Clinical also lists Active Serum in its Pre & Post Partum collection.
