Not To Be Combined With…

When addressing the needs of problematic skin, active ingredients such as retinol, benzoyl peroxide and alpha-hydroxy acid are often found in recommended skin care products. Their effectiveness varies; however dermatologists agree that mixing these strong ingredients can be counter- productive.

Retinol and benzoyl peroxide are exfoliating agents that clear existing acne and prevent new blemishes from forming due to its drying effects.  When mixed together, or even layered, the skin can experience excessive peeling, flaking, redness, and blistering, scarring and unwanted pigmentation.

Alpha-hydroxy acid- a chemical found in natural products acts as an exfoliating agent and can be used in combination with retinol. When using these together, the AHA should be applied in the morning whereas retinol is to be applied at night.

These aforementioned ingredients may cause increased sun sensitivity. Therefore, it is critical to wear a good, daily sunscreen to counteract UV sensitivity.

If you use retinol, benzoyl peroxide and/or alpha-hydroxy acid, be mindful of the amount you use. These ingredients are potent and often cause irritation. When using products with these ingredients, dermatologists suggest using small amounts at first in order to build tolerance.

For more information about these ingredients and/or other products that address problematic skin, consult your dermatologist at Knoxville Dermatology Group.

Benzoyl Peroxide: Key Ingredient,Key for You?

Benzoyl Peroxide is one of the most commonly prescribed anti-acne ingredients. However, regular use of benzoyl peroxide may be the source of possible skin problems. Knoxville Dermatology Group encourages you to learn more about active ingredients, such as benzoyl peroxide, found in many skin care products.

What is Benzoyl Peroxide?
Benzoyl Peroxide is medication used to treat mild to moderate acne. When applied to the skin, benzoyl peroxide works by reducing the amount of acne-causing bacteria and by causing the skin to dry and peel.  There are many benzoyl peroxide products available; many can be purchased without a prescription. However, a dermatologist should recommend the appropriate products upon assessment of skin.

The Pros
Clears Acne Fast
Benzoyl peroxide clears blemishes fast by killing acne-causing bacteria.  Products that contain lower concentrations are as effective as those with higher concentrations.  Thus, skin does not have to endure dryness to achieve desired results.

 

Acts as an Anti-Inflammatory Agent
According to a study published in Cosmetic Dermatology, benzoyl peroxide reduces oxygen in the skin and bacteria in the pore. Moreover, the ingredient works to reduce inflammation within the blemish.

The Cons
Causes Dehydration and Premature Aging
Benzoyl peroxide causes irritation, namely dryness, which in turn ages skin. Vigilant use of moisturizers can help this drawback.

 

 

Can Lead to Hyperpigmentation
Post inflammatory hyperpigmentation is characteristic of acne and benzoyl peroxide adds to its severity. Hyperpigmentation is especially severe for people of medium to dark skin tones.

 

Induces Sun Damage
Because benzoyl peroxide cleans the pore, it thins the skin increasing susceptibility to sun damage.

 

Common Side Effects
Dryness and peeling; skin that feels tight. Redness may occur.

How to Use It
Dermatologists agree the key with benzoyl peroxide is moderation. It was invented as a product for short-term use, thus users should take heed and scale back use.  If side effects are still an issue, there are many other agents, like salicylic acid and retinol that work just as well.
