Dark marks, brown spots \u0026amp;amp; more: hyperpigmentation, demystified.Brown spots have a major influence on how old people think we are. In fact, one study showed that unbalanced skin tone can make a person look more than 12 years older! The big questions: where do they come from, and what can you do about them?It helps to understand the science behind brown spots. The official term for brown spots and other forms of skin discoloration is hyperpigmentation. Unlike freckles, hyperpigmentation doesn\u0026#39;t fade in winter and, unfortunately, it becomes more visible as we age.But what causes it? Irregular production of melanin (the brown or reddish pigment in skin). Certain triggers – unprotected sun exposure in particular – causes this irregular production, which leads to surface color-clumping. Other causes include hormonal factors (birth control pills and pregnancy), and post-inflammatory hyperpigmentation (PIH) caused by past trauma or scarring (think a popped pimple or a deep cut). Hormonal hyperpigmentation and PIH are both intensified by sun exposure.30 minutes unprotected in the sun can undo a month\u0026#39;s worth of effort in fighting hyperpigmentationSo, what to do about it? Here\u0026#39;s how to figure out what\u0026#39;s causing your brown spots – and take action.Call in the expertsDespite Ask a Dermalogica skin therapist for a free Face Mapping® skin analysis and consultation to get to the root of your brown spots.

As one of the most potent antioxidants available, it\u0026#39;s highly effective at scavenging free radicals. New research shows that it can also enhance skin\u0026#39;s natural defense system, helping it defend itself against future oxidative stress – effectively brightening skin from inside and out. Just make sure to choose a Vitamin C formula that\u0026#39;s both ultra-stable and highly bioavailable.Be patientThere\u0026#39;s no quick fix for hyperpigmentation: it can take at least 30 days of skin care treatment (with sunscreen use) before you see any progress. Additionally, some spots may look darker before they lighten; this is because they gradually rise to the skin\u0026#39;s surface as you continue to exfoliate. But stick with it, and you\u0026#39;ll eventually see brighter, firmer, more radiant skin!BioLumin-C Serum is a high-performance Vitamin C serum that works with skin\u0026#39;s own defenses to brighten and firm.
