iS Clinical Brightening Complex is a daytime treatment formulated to hydrate, protect, and gradually brighten with stabilized vitamin C and botanical extracts in a moisturizer-like texture. iS Clinical Brightening Serum is a nighttime treatment with a higher concentration of exfoliating and pigment-correcting actives for deeper correction while you sleep. Used together as an AM and PM pairing, they create a complete brightening regimen that addresses tone around the clock.

Most sensitive skin types tolerate iS Clinical Brightening Complex well because the formula pairs its active botanicals with a hydrating, barrier-supportive base of hyaluronic acid, squalane, and glycerin. The exfoliating ingredients, including willow bark extract and fruit acids from sugarcane and bilberry, are present at levels intended to be gradual rather than aggressive. If your skin is reactive, start with once-daily use and increase frequency as your skin adjusts. Our estheticians are also available for a free skincare consultation if you would like personalized guidance.

It depends on your skin type and the season. Normal to oily skin types typically find that iS Clinical Brightening Complex provides sufficient hydration on its own as a daytime moisturizer, thanks to hyaluronic acid, squalane, and imperata cylindrica root extract. If your skin runs dry or feels tight after application, layering a richer moisturizer on top is a simple and effective adjustment.

Most users notice improvements in radiance and surface texture within two to four weeks of consistent use. Visible reduction in dark spots and hyperpigmentation typically becomes apparent after six to eight weeks. Results build over time, so daily application, combined with broad-spectrum SPF in the morning, will give you the most reliable outcome.

Yes, the two work well together when applied at different times of day. Use iS Clinical Brightening Complex in the morning to brighten and protect, then apply your retinol product at night. Because Brightening Complex contains gentle exfoliating botanicals, monitor your skin in the first few weeks and reduce frequency if you notice any sensitivity building.

Extremozymes are a proprietary ingredient technology found in iS Clinical formulas, derived from microorganisms that survive in extreme environmental conditions such as high UV radiation or intense heat. In skin care, they provide DNA-repairing activity and help protect cells from oxidative damage caused by sun exposure, pollution, and other environmental stressors. Their inclusion in iS Clinical Brightening Complex supports not just immediate brightness but long-term skin resilience.

iS Clinical Brightening Complex contains citrus aurantium dulcis (orange) oil, which gives the formula a light, natural citrus scent. No synthetic fragrance is added. Most users find the scent subtle and pleasant, but if you have a sensitivity to essential oils or citrus-derived ingredients, this is worth noting before purchasing.
