question

What's the best product to use to cure hyperpigmentation due to acne? Has hydroquinone been declared safe?

ANSWER
Luckily, these days, there are many very effective products formulated to treat hyperpigmentation, whether the source of the problem is acne, hormones, scarring, or sun damage. Look for the words 'lightening' or 'brightening' or 'clarifying' or even 'detoxifying', when searching for a product to help with the condition. Ingredients such as fruit acids, kojic acid, hydroquinone (be careful-- it can cause allergies in some individuals), vitamin C, vitamin A, licorice, mulberry and bearberry extracts have all been shown to help speed up the rate at which hyperpigmention fades. As well, in-spa treatments such as glycolic or lactic acid peels (or a combination of) enzyme peels or microdermabrasion can help speed the exfoliation rate of melanin rich dead cell layers, so the darker appearing areas lift more quickly. Our favorite dark spot diminishing multi-tasking approach is the Beurer Softlaser Healer. Whichever product you end up using, be sure to always layer on an SPF 15 (or higher such as Bliss Oil-free Sunban Lotion For The Face With Spf 30) during daytime hours, to prevent ultra-violet radiation from setting your anti-pigment strategy back in its tracks.
