After gradually stopping hydroquinone, you might be transitioned to alpha arbutin and alongside retinol or prescription retinoid. This will stabilise the melanin producing cells and reduce the chances of rebound hyperpigmentation.
No, the hydroquinone won't hurt you if it turns brown but it won't be effective either because it has oxidized or degraded. I would recommend throwing it out after a year or sooner, if it turns brown throughout the tube.
Using Hydroquinone Responsibly
It is also important that you take breaks in between use of hydroquinone. 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.
After gradually stopping hydroquinone, you might be transitioned to alpha arbutin and alongside retinol or prescription retinoid.
To reduce this risk, doctors often recommend “cycling” Hydroquinone. This means using it for a limited period followed by a break.
Put the sunscreen on the dark areas after using Hydroquinone to prevent the condition from coming back. Dark spots might return if you stop using the cream, but this is less likely if you protect your skin from the sun.
According to doctors, damage caused by the application of hydroquinone can be reversed by exposing the affected area to the sun. Also, you are recommended to use strong sunscreen along with hydroquinone. In case of irritation, apply anti-itch cream to the infected skin.
INGREDIENTS CAN OXIDIZE:
Generally, you can tell that something has oxidized because it will turn a yellow-ish or brown-ish color. Sometimes this color shift doesn't greatly impact the efficacy of the product. But sometimes, this oxidation can be a sign that the ingredients inside the product are no longer potent.
Once the hydroquinone has oxidized, it is no longer active and should be discarded. Prescription hydroquinone formulations have tried to increase the potency of formulations by adding penetration enhancers such as glycolic acid, sunscreens, and tretinoin as a supplemental pigment lightening agent.
With GRAS (Generally Recognized as Safe) status, hexylresorcinol is a great choice for beauty brands seeking to provide skin lightening and even toning benefits in their next skin care formula. Hexylresorcinol was introduced to the skin care market in 2007 under the trade name Synovea® HR.
One concern is that it may cause the opposite effect of hyperpigmentation, called ochronosis. This is a condition where the skin becomes dark and thick, which can be difficult to treat. Hydroquinone can also cause skin irritation, especially if it is used in high concentrations or for long periods of time.
Kojic Acid offers antioxidant support and brightens skin tone while Niacinamide helps to improve pigmentation, resulting in a more flawless, radiant complexion.
10% azelaic acid over the counter products have also been shown to improve hyperpigmentation concerns such as post-inflammatory hyperpigmentation from acne, sun spots, and melasma; the results being equal to 4% pharmaceutical HQ. Kojic acid is another acid that specializes in reducing unwanted pigment within the skin.
Remember that alpha arbutin can be used for 4-5 months then take a break for two months and restart. ✅For black heads : Salicylic acid is preferred over glycolic acid as it gets concentrated in oil forming glands and also reduces sebum production.
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.
They are most common in people over the age of 40 (hence the name) but they can occur earlier.
The lesions may develop gradually over 6 months to 3 years or longer. [8] Two recent case reports from India mention the occurrence of EO with use of 2% hydroquinone preparations for 7–8 years.
taper the Hydroquinone. Gradual cessation will minimize any rebound increase activity of tyrosinase. o Apply only 3 times per week for 2 weeks. Then 2 times per week for 2 weeks, then stop use.
Protect your skin: After applying hydroquinone, it is crucial to protect your skin from sun exposure. Apply a broad-spectrum sunscreen with a high SPF to the treated areas, even if you're indoors. This helps prevent further hyperpigmentation and protects your skin from harmful UV rays.
A diet which is rich in vitamin C (1g/day) may also be beneficial. Vitamin C has been found to slow down the conversion of HGA to the pigmented deposits in connective tissue. There has also been recent research on the use of nitisinone, a potent inhibitor of the second enzyme in the tyrosine catabolic pathway.
Vitamin C goes first, followed by hydroquinone if the former is in serum and the latter in a moisturizer. It's important to let your skin dry after using vitamin C serum and before hydroquinone cream.
