iS Clinical - Radiance Collection
If your skin has started to look a little flat, uneven, or tired, and you've been wondering whether a more targeted routine might help, the iS Clinical Radiance Collection is worth a close look. Rather than a single product, this is a curated bundle of five complementary formulas, each addressing a different step in the brightening process, from cleansing and exfoliation through to treatment, moisture, and eye care.
- Suitable for all skin types, particularly those dealing with dullness, uneven tone, or early signs of ageing
- Designed to work as a cohesive routine rather than a collection of standalone products
- Combines daily skincare steps with an intermittent exfoliating treatment
- Addresses texture, tone, and hydration within a single, structured kit
- Developed by iS Clinical, a professional-grade skincare brand with a background in clinical and medical aesthetics

What Is It?
The Radiance Collection is a five-product skincare kit from iS Clinical, a US-based brand known for formulating products to professional and clinical standards. The collection is built around a brightening and refinement goal, bringing together products that target dullness, uneven skin tone, surface texture, and dehydration.
Rather than asking you to research and assemble individual products, the collection pairs a gentle daily cleanser with a treatment serum, a two-step exfoliating peel, a reparative moisturiser, and an eye complex. Each step feeds into the next, which is what distinguishes a curated kit from a miscellaneous bundle. The overall routine is designed to prepare the skin, deliver active ingredients where they matter, and then support the barrier with hydration and protection.
It positions itself for anyone who wants a clearer, more luminous complexion but does not necessarily need a clinical-level intervention. It is equally relevant for those building their first proper routine as for those looking to upgrade an inconsistent one.
How To Use It
The collection is intended to be used morning and evening for most steps, with the Active Peel System used less frequently to avoid over-exfoliation.
- Cleansing Complex (morning and evening): Apply a small amount to damp skin, massage gently over the face and neck, then rinse thoroughly and pat dry.
- Active Serum (evening only): Apply 3 to 4 drops to the palm, then press and smooth evenly over the face and neck. A mild tingling sensation is normal and will settle within a few minutes.
- Active Peel System (every other evening, after cleansing): Apply Step 1 over the face and neck and leave for three minutes without rinsing. Apply Step 2 over the same area and leave on. Both steps will produce a cool tingling sensation; this is expected.
- Reparative Moisture Emulsion (morning and evening): Apply a small amount to clean skin and smooth evenly over the face and neck.
- Youth Eye Complex (morning and evening): Using fingertips, dab a small amount around the outside of the eye area, including the brow bone and under-eye area. Avoid the inner corners.
Note: the Active Serum and Active Peel System should not be used on the same evening.
Whats In It?
The Radiance Collection is a bundle of five products. It does not have a single shared formula; each item contains its own active ingredients tailored to its step in the routine. Below is a summary of the key components within each product.
Cleansing Complex (180ml) A gel cleanser containing willow bark extract (a botanical source of salicylic acid), sugarcane extract (an AHA), green tea leaf extract, and chamomile. It also includes centella asiatica components (asiaticoside, asiatic acid, and madecassic acid), which are known for their calming and skin-supporting properties. Vitamin E (tocopheryl acetate) and vitamin A (retinyl palmitate) are also present. The cleanser is designed to gently remove impurities while preparing the skin for treatment steps.
Active Serum (3.75ml trial size) A lightweight treatment serum containing botanical-derived acids: sugarcane extract (a source of glycolic acid), bilberry extract (a source of lactic acid), and white willow bark (a botanical source of salicylic acid). These work together to support gentle surface exfoliation. Arbutin, derived from bearberry, is included for its role in addressing uneven pigmentation and dark spots. Mushroom extract supports skin conditioning and brightness. The serum is formulated without parabens.
Reparative Moisture Emulsion (50g) A hydrating moisturiser built around sodium hyaluronate (hyaluronic acid) for deep hydration, squalane for barrier support, and a copper tripeptide-1 for its established role in supporting skin structure and addressing the appearance of fine lines. Superoxide dismutase, an antioxidant enzyme, helps protect skin from environmental oxidative stress. Glycerin and caprylic/capric triglyceride provide additional moisture and emollient properties.
Active Peel System (2.6ml pads) A two-step exfoliating treatment containing fruit acids, botanical extracts, and a copper tripeptide-1 component. It resurfaces the skin, supports cell renewal, and works to improve overall tone and texture over time. The two-step application process is designed to enhance penetration and efficacy.
Youth Eye Complex (1g trial size) A targeted eye treatment. Specific ingredient details were not fully available in the source material, but the product is formulated for use around the delicate eye area, addressing the appearance of fine lines and supporting brightness in that region.
Why We Recommend It
The Radiance Collection represents a considered entry point into iS Clinical's professional-grade range. What makes it worth exploring is the coherence of the formula selection: each product has a defined role, and together they address the full brightening process rather than simply stacking similar actives.
The inclusion of both a daily exfoliating serum and a separate peel system is notable. Rather than duplicating effort, the two work at different levels and on different days, offering flexibility without overlap. The Reparative Moisture Emulsion and Youth Eye Complex add targeted support that many brightening-focused kits overlook.
The use of botanical-derived acids rather than direct synthetic equivalents in some products may make the collection more suitable for those with sensitivity concerns, though the Active Peel System in particular involves genuine resurfacing activity and should be introduced gradually.
At £115, the collection offers a multi-step routine that, if purchased individually, would cost considerably more. It suits those who prefer a structured approach and want products that are professionally formulated and developed for visible results rather than everyday cosmetic use.
What To Expect
Most people using the routine consistently will begin to notice improvements in skin texture and brightness within two to four weeks. The Cleansing Complex and Active Serum work incrementally to refine the surface, while the Active Peel System provides more focused resurfacing on the days it is used.
The Active Serum produces a mild tingling sensation on application; this is typical and should pass within a few minutes. The Active Peel System similarly produces a cool, tingling feeling during the two-step application, which is expected and not a cause for concern.
The Reparative Moisture Emulsion is generally well tolerated and should help counterbalance any dryness that can accompany regular exfoliation. Those with sensitive skin may wish to introduce the peel system more slowly, starting once a week and building up as their skin adjusts.
Results will vary depending on skin type, starting condition, and consistency of use. The collection is not positioned as a treatment for medical skin conditions.
