The best remedy is prevention, but chances are you already have a dark spot or two... (or many!)
In order to prevent these pesky patches of skin, avoid wearing citrus oils and perfumes in direct sunlight because they can cause dark spots on the skin. Many skin care products can also make the skin photosensitive (sensitive to the sun). Check the labels of your products, especially facial peels with fruit acids. Antibiotics also make your skin sensitive to the sun, resulting in hyperpigmentation if left unprotected.
To lighten dark spots, look for products with hydroquinone, kojic acid or licorice extract (glycyrrhizinate). Glycolic acid or calendula cream may also help slowly fade hyperpigmentaion. If all else fails, consult your dermatologist and ask about a peel or a prescription strength fade cream.
Not sure where Prtty Peaushun falls on the spectrum of photo-safe products? Luckily, PP passes with flying colors. Bethany Karlyn explains that:
Regarding Hyper pigmentation (melasma), avocado is rich in fatty acid, vitamin C and oleic acid, all of these ingredients are good for hyper pigmentation treatment. It is thought that Grapefruit essential oil is not phototoxic, unlike most of the other citrus oils; although Grapefruit oil does contain furocoumarins, which are responsible for phototoxic effects, it also contains other chemical components which appear to neutralize the potential phototoxicity. When hyper pigmentation is caused by sun damage, the strong antioxidants in the formula that protect the skin against sun damage are Japanese Green Tea and Rosemary. Every single ingredient in Prtty Peaushun has a benefit for the skin and all together are a perfect combination to repair the skin, using it daily. We have had great results in diminishing dark spots with regular use of Prtty Peaushun. Use the Plain every night before bed to see amazing results!
And as always, the best remedy is prevention. Wear sunscreen always and a hat if possible.
