Chan both agree hydroquinone does not play well with benzoyl peroxide, hydrogen peroxide, or other peroxide products. Not only will pairing them cause irritation and dryness, but it can also temporarily stain your skin.
Avoid using hydroquinone with peroxide products such as benzoyl peroxide or hydrogen peroxide, which can cause discoloration. 3. Avoid alpha hydroxy acids. The combination of hydroquinone and alpha hydroxy acids (AHAs) can irritate your skin.
2.2. 2 Oxidation of hydroquinone Hydroquinone is oxidized by a variety of oxidants including nitric acid, halogens, persulfates and metal salts (NIOSH, 1978). It is also oxidized by molecular oxygen in alkaline solutions. Hydroquinone reacts with molecular oxygen (autooxidation).
Combining the effects of hydroquinone and azelaic acid can more effectively address the various hyperpigmentation pathways. Azelaic acid is a wonderful complement for people with sensitive skin because it can help reduce any potential irritation or sensitivity brought on by using hydroquinone.
Hydroquinone + Mometasone + Tretinoin is a combination of three medicines: Hydroquinone , Mometasone and Tretinoin, which treats melasma (dark spots on skin). Hydroquinone is a skin lightening medicine. It reduces the amount of a skin pigment (melanin) that causes darkening of skin. This effect is reversible.
A major key to hydroquinone is short-term use. You can slather it on twice daily for at least six weeks (and no more than six months). After one to three months, you should start to see your hyperpigmentation fade away.
Combination Tip: Combining hydroquinone with Vitamin C may improve overall efficacy, but due to potential sensitivities, this combination should only be used under the supervision of a dermatologist. Sunscreen: How It Works: Sunscreen is essential for preventing further hyperpigmentation caused by UV exposure.
Hydroquinone and Retin-A (Tretinoin)
When used with Hydroquinone, it can speed up the process of fading hyperpigmentation. These two ingredients can be found together in compound preparations or used as separate products for more control.
The hydrogen peroxide decomposes and the hydroquinone reacts to form benzoquinone (C6H4O2). The resultant hydrogen reacts with the oxygen to produce water.
Arbutin has been found to be the most effective active ingredient in our study, even more so than hydroquinone, despite being a naturally occurring derivative.
According to research, ochranonsis is a condition that might occur following long-term application of skin-lightening creams containing hydroquinone. Ochranosis may cause darkening of the skin, instead of fading a particular spot. Long-term use of Hydroquinone creams may also lead to exogenous ochronotic lesions.
Alternative lightening agents including mequinol, arbutin, kojic acid, and others have shown comparable efficacy to hydroquinone in treating hyperpigmentation with less concerning side effects.
While oral consumption probably is not related to topical application, hydroquinone remains controversial because it actually is toxic to melanocytes. Hydroquinone, a phenolic compound chemically known as 1,4 dihydroxybenzene, functions by inhibiting the enzymatic oxidation of tyrosine and phenol oxidases.
Hydroquinone has no known severe, serious, moderate, or mild interactions with other drugs.
Hydroquinone is a bleaching cream that is used to lighten the skin tone and brown spots. Both products are used to keep enhancing your skin's color and glow after popular procedures like Botox or Acne treatments. Hydroquinone and Retin-A can be used together following the instructions below.
The combination of tretinoin and hydroquinone cream is considered one of the best treatments for hyperpigmentation and melasma. It is also effective for post-inflammatory hyperpigmentation from acne, eczema, and psoriasis.
Hydroquinone is a white, odorless, crystalline solid with an extremely low vapor pressure. It is moderately soluble in water and highly soluble in alcohol.
Rarely ochronosis - ochronosis is a blue-black or gray-blue discoloration; it is rare and more commonly seen in patients that use a high concentration of hydroquinone for a long period on large areas of the body.
Avoid irritants: Be mindful of other skincare products or ingredients that may potentially irritate your skin. Avoid using harsh cleansers, exfoliants, or other products that can cause irritation or sensitivity while using hydroquinone.
Vitamin C works best when used during the daytime because of its ability to protect the skin from free radicals and oxidative stress caused by UV exposure and pollution. Hydroquinone is most effective at night, making these two ingredients the perfect morning-and-evening combination.
Tretinoin is an anti-aging powerhouse, meaning it should have no problem dispatching fine lines and wrinkles. It does not work for deeper wrinkles. Hydroquinone doesn't work at all against fine lines and wrinkles, so stick to the collagen-boosting power of tretinoin.
4) Why does my skin look darker after using Vitamin C? If you are applying Vitamin C without sunscreen, it is likely that the Vitamin C degrades into Erythrulose, which is an ingredient you will find in many self-tanners. So please make sure you apply sunscreen always after applying Vitamin C.
Conclusion. A cream formula containing 4% hydroquinone + 10% glycolic acid + 0.01% hyaluronic acid was very effective in treatment of melasma with tolerable side effects. Dermoscope is a valuable noninvasive tool in the diagnosis and follow-up of melasma treatment.
