Published Studies Related to Glyquin XM (Hydroquinone / Glycolic Acid)

Evaluation of a kojic acid, emblica extract, and glycolic acid formulation compared with hydroquinone 4% for skin lightening. [2010.09]
Hydroquinone has been the standard prescription agent for skin lightening; however, its use recently has become controversial. Hydroquinone is banned in Europe and parts of Asia because of potential long-term consequences, including carcinogenesis when orally consumed... Thus this novel skin lightening preparation is an alternative to hydroquinone 4% for participants with mild to moderate facial dyschromia.

Comparative evaluation of beneficiary effects of priming agents (2% hydroquinone and 0.025% retinoic acid) in the treatment of melasma with glycolic acid peels. [2008.08]
BACKGROUND: Chemical peels have become a popular modality in the treatment of melasma. The most disturbing side effect of this procedure is postinflammatory hyperpigmentation. This may be minimized with the help of priming agents. Because there is a paucity of such studies, this study was taken up to evaluate the beneficial effects of hydroquinone versus tretinoin as priming agents in treatment of melasma with glycolic acid peels... CONCLUSIONS: Results are better with hydroquinone as priming agent compared to tretinoin in enhancing the results with glycolic acid peels in melasma and in decreasing postpeel postinflammatory hyperpigmentation.

Safety and efficacy of 4% hydroquinone combined with 10% glycolic acid, antioxidants, and sunscreen in the treatment of melasma. [2003.12]
BACKGROUND: Melasma, also known as mask of pregnancy, is a common, acquired hypermelanosis seen in women with Fitzpatrick skin types II-V, and is often recalcitrant to treatment with depigmentation agents. Glycolic acid has been added to hydroquinone formulations in the past to enhance their depigmentation effects, but may cause irritation, leading to postinflammatory hyperpigmentation. AIM: To assess the safety and efficacy of a cream containing 4% hydroquinone, 10% buffered glycolic acid, vitamins C and E, and sunscreen (Glyquin, ICN Pharmaceuticals, Costa Mesa, USA) vs. a cream containing sunscreen alone in the depigmentation of epidermal melasma of the face... CONCLUSIONS: A cream containing 4% hydroquinone, 10% buffered glycolic acid, vitamins C and E, and sunscreen is safe and effective in the treatment of melasma.

Efficacy of hydroquinone cream (USP 4%) used alone or in combination with salicylic acid peels in improving photodamage on the neck and upper chest. [2000.04]
BACKGROUND: Salicylic acid, hydroquinone, and glycolic acid have been proved effective in the treatment of photodamaged facial skin. Few reports are available on the treatment of photodamage on the neck and upper chest. OBJECTIVE: This study's purpose was to evaluate the efficacy of a cream containing 4% hydroquinone and 2% glycolic acid (LUSTRA) used alone or with salicylic acid peels in reversing actinic damage on the neck and upper chest... CONCLUSION: Hydroquinone 4% cream with 2% glycolic acid is safe and effective in improving photodamage on the neck and upper chest when used alone or in combination with salicylic acid peels.

Treatment of melasma using kojic acid in a gel containing hydroquinone and glycolic acid. [1999.04]
BACKGROUND: Melasma is difficult to clear. Many agents have been used, such as hydroquinone, and glycolic acid and glycolic acid peels, kojic acid, a tyrosinase inhibitor in the fungus Aspergilline oryzae. OBJECTIVE: To see if the addition of 2% kojic acid in a gel containing 10% glycolic acid and 2% hydroquinone will improve melasma further... CONCLUSION: The addition of kojic acid to a gel containing 10% glycolic acid and 2% hydroquinone further improves melasma.

Clinical Trials Related to Glyquin XM (Hydroquinone / Glycolic Acid)

Clinical Trial of Hydroquinone Versus Miconazol in Melasma [Recruiting]
Melasma is an acquired discoloration of the skin characterized by brown colour changes commonly on the face. The duration of this double-blind clinical trial will be 12 weeks. The control group will receive treatment with topical Hydroquinone (4%), and the other group topical miconazole. Miconazol has antimelanotic properties and can be used as treatment for melasma patients. The estimated number of subjects to be recruited and randomized for the study is at least 30. The purpose of this study is determine if there is a difference in the effectiveness of these two agents. Melasma Area and Severity Index (MASI) score will be assessed at the beginning of the study and at weeks 4, 8, and 12. Photographs, colorimetry and histological assessment will be also evaluated. Occurrence of adverse effects will also be recorded.

Azelaic Acid Versus Hydroquinone in Melasma [Recruiting]

Salicylic Acid Peels Combined With 4% Hydroquinone in the Treatment of Moderate to Severe Melasma in Hispanic Women [Active, not recruiting]
This study will enroll 20 adult Hispanic women. Participants will apply 4% hydroquinone cream twice daily to affected areas on the face for 14 weeks and half the face will be peeled with 20-30% salicylic acid every two weeks for a total of 4 peels. The first two peels will be 20% salicylic acid and the second two peels will be with 30% salicylic acid. The purpose of the study will be to evaluate the safety and efficacy of salicylic acid combined with 4% hydroquinone versus 4% hydroquinone alone.

Effectiveness of Low Dose Complex B-Vitamins on Homocysteine Lowering Among Chinese Elderly--Randomized Control Trial (RCT) [Recruiting]
The purpose of this study is to evaluate whether low dose complex B-vitamins (folic acid,vitamin B6 and vitamin B12) can lower the risk of developing hyperhomocysteinemia in an apparently healthy population with low folate/B12 and high Hcy status.

Bone Health in Pregnancy [Recruiting]
Women between the ages of 19 and 40 are needed for a study that looks at the effect of calcium and vitamin D supplementation on bone health during pregnancy in black and white women. Study subjects will be divided into three groups. Each group will take 2 study supplements each day, the supplement will be calcium, vitamin D or placebo (a pill with neither calcium nor vitamin D). The study involves five visits to the Children's Hospital of Oakland Research Institute; each visit will be 1-2 hours in length. There are 3 study visits during pregnancy and 2 in the first year after delivery. At each visit you will have your blood drawn and be asked questions about what you eat and what type of activities you do. At visit 16 and 36 weeks and 4 and 12 months postpartum you will have your bone density measured. You will be paid $235 for completing the study.
