This medicine will work best if you avoid excessive exposure to sunlight and wear sunscreens and protective clothing. Some hydroquinone products contain sunscreens. Use a sunscreen (SPF 15 or higher). Do not use sun lamps or sun tanning beds or booths.
However, medical guidelines specify that you should stop using hydroquinone if you haven't seen any results after about three months. Your doctor may recommend you try some new products that combine hydroquinone with other ingredients, such as glycolic acid.
Turegano and Dr. 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.
We recommend taking a 2 month break after 3 months of application. Since hydroquinone is a photosensitive agent, It is also important to use SPF 30 or higher daily when on hydroquinone.
It has surprisingly been found that citric acid has the ability to stabilize hydroquinone solutions in such solvents as diethylene glycol and methoxythanol for periods of at least 2 months, while such solutions containing other acids such as fumaric, salicyclic, benzoic and adipic acid darken in periods ranging from 2- ...
This disease entity may be first noticed in newborns as their urine may be darker than normal. People are often without symptoms until later in life when the skin, sclera (white part of the eye), ears, and nose may develop pigmentary changes. Ear wax of a person with ochronosis will also be dark in color.
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.
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.
Hydroquinone and Alpha Hydroxy Acids (AHAs)
AHAs, like glycolic acid and lactic acid, exfoliate the skin and boost cell turnover. When used with Hydroquinone, these acids can enhance the skin lightening and acne scar fading effect of Hydroquinone.
Continue prescribing hydroquinone for no more than four to five months. Allow the skin to rest and restore itself for two to three months after hydroquinone therapy. Resume hydroquinone therapy, if needed, only after such a break.
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.
Alternative lightening agents including mequinol, arbutin, kojic acid, and others have shown comparable efficacy to hydroquinone in treating hyperpigmentation with less concerning side effects.
If there has been no benefit after 3 months of treatment, then the hydroquinone should be stopped. Management of the underlying cause of the hyperpigmentation is also recommended. When initiating hydroquinone treatment, it is advisable to: Start with a test area about 1 cm in diameter.
Hydroquinone has a pretty short shelf life. After a couple of months, it can start to break down and lose its potency, meaning it becomes less effective.
Hydroquinone. Hydroquinone is a depigmentation agent that is present in many skin bleaching products. A person can buy a 2% solution over the counter or seek a prescription for a stronger 4% solution.
Vitamin C is an excellent agent for the treatment of abnormal pigmentation; however, its instability and lack of penetration into the skin prevent it from being a highly effective means of treating melasma and PIH.
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.
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.
Although hydroquinone primarily acts by suppressing tyrosinase activity, it has little effect on inflammation [48]. Therefore, azelaic acid's dual mode of action may give a more comprehensive treatment approach for melasma, with better results than hydroquinone alone, as observed in this study.
Ochronosis resulting from the use of 2% hydroquinone has been described. There are various theories that explain exogenous ochronosis. The most accepted is that of Penneys18 who attributed the hyperpigmentation to the inhibition of the enzyme homogentisic oxidase by hydroquinone.
Melasma is a symmetric progressive hyperpigmentation of the facial skin that has a predilection for darker skin phenotypes. [1] Exogenous ochronosis (EO) is an uncommon disorder characterized by the deposition of microscopic, ochre-colored pigment in the dermis, giving rise to a blue-black hue in the skin.
Multiple options for topical treatment are available, of which hydroquinone (HQ) is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin.
