How Hydroquinone 4 Cream over the counter works

Hydroquinone 4 USP cream also known as quinol or short-name HQ 4% – a skin lightening cream. The creams are for normal to oily/combination and dry skin help limit skin from creating an excessive amount of melanin, which is what gives skin its color. Too much melanin clustered together leads to brown spots and freckles. Hydroquinone steps in to interrupt this process, causing brown spots to gradually fade. Hydroquinone 4 creams can be helpful for old, stubborn, and advanced brown/dark spots. In not as severe cases it is recommended to use not so strong cream, for example, Azelaic Acid 20% or hydroquinone 2% or 3%. For mild hypopigmentation issues better suitable hydroquinone HQ 2%, azelaic, kojic, and glycolic acids, combined with vitamin C serums. Patients can see impressive results fast with the HQ 4 USP cream.

Hydroquinone 4.0 cream OTC releases certain enzymes that block the production of melanin to make the skin a lot lighter and brighter in tone, decreasing skin pigmentation and dark patches. Since the amount of melanin is decreased by active ingredient quinol and enzymes, the darker skin gradually lightens to match the overall lighter skin tone color. Hydroquinone 4 cream is also effectively used in combination with retinoids to maximize skin lightening and exfoliating effects.

Check the label for directions before use. 4 percent Hydroquinone is used to lighten the dark patches of skin (also called hyperpigmentation, melasma, “liver spots,” “age spots,” freckles”) caused by pregnancy, birth control pills, hormone medicine, or injury to the skin.

Getting the most benefit from Hydroquinone 4% cream

With daily usage, hydroquinone 4 cream produces visible results within 1-2 months (4-8 weeks) of consistent use. Always use HQ 4 USP skin lightening cream with caution, in small amounts and under strict dermatologist supervision, also with strong SPF sun blockers (important to reapply regularly), moisturizers, wearing big sunglasses within total sun avoidance program, it is an essential part to achieving great results with these creams. If used as directed by the dermatologist with strict sun protection measures, this decreases the risk of skin cancer and early skin aging caused by the sun.

It’s essential for quinol products to be packaged in an opaque metallic/plastic container that minimizes air exposure. Quinol degrades in the presence of air, that’s why our Hydroquinone 4 creams packaged/sealed in special tubes, not in a jar. Once the jar is opened it lets air in, and the hydroquinone loses its potency.

How does Hydroquinone 4% Cream work

Creams contain the chemical element hydroquinone 4 also known as HQ 4% or tyrosinase, which is an enzyme responsible for producing melanin, the pigment that determines the overall color of our skin. The hydroquinone works in two separate and opposing ways:

  • First, it decreases melanin production in the respective cells of the skin;
  • Second, it increases melanosome breakdown (melanosome contains the melanin).

The less melanin is present, the more the darker skin begins to match the normal skin color of the patient.
