Bumpy, rough skin is a common complaint among people with many different skin types and can be caused by a variety of skin conditions, including keratosis pilaris, folliculitis, and dry skin due to an impaired skin barrier.
Find out how to tell if you might be dealing with one of these common dry skin conditions and what the best treatment options are to get rid of and prevent rough bumpy skin in the future.
What are rough bumps on skin?
Keratosis pilaris, often referred to as KP, is a common skin condition that causes dry, sandpaper-like bumps on the skin, usually on the arms and outer thighs. These bumps, caused by an increase in keratin production, are typically red or flesh-colored and do not itch or hurt. While KP bumps are harmless, they can be unsightly if left untreated, so many men and women with these rough bumps choose to speak with a dermatologist about the best treatment options for KP.
Exfoliation and moisturization are the two most important steps when treating KP bumps. Exfoliants help to remove the buildups of keratin on the skin that create these bumps, while moisturization helps to prevent continued keratin buildup in the future.
The type of exfoliant to choose for your skin care routine depends upon your skin type. Sensitive skin, for example, tolerate chemical exfoliants such as hydroxy acids better than physical exfoliants such as scrubs.
Here are some dermatologist- recommended body scrubs:
Why do we get goosebumps?
Goosebumps are a physiological phenomenon that occur as part of the body's fight-or-flight response, which is triggered by various forms of stress including cold temperatures, fear, or emotional arousal. When we are cold, the contraction of small muscles called arrector pili at the base of hair follicles (caused by the release of the neurotransmitter norepinephrine) pulls the hairs upright. In furry animals, this action creates an insulating layer of air trapped beneath the erect hairs, helping the animal to retain heat. In humans, this response is largely vestigial, as we have significantly less body hair, but it follows the same pattern. When we are scared or emotionally stimulated, the same fight-or-flight response is activated. In this context, the piloerection reflex is thought to be a defensive mechanism that, in animals, makes them appear larger or more threatening to predators.
For humans, goosebumps during emotional moments, such as while listening to a moving piece of music, are a lingering echo of this ancient reflex, showcasing the profound link between our emotions and physiological responses, even when the response itself no longer serves a clear practical function.
Red, pus-filled bumps that appear in areas where you shave, such as under your arms, on your legs, or face, are likely caused by a condition called folliculitis. Folliculitis occurs when a hair follicle becomes inflamed, usually caused by a bacterial or fungal infection.
In addition to shaving, wearing tight-fitting clothing when working out, not changing clothes immediately after sweating, and soaking in improperly-maintained hot tubs can cause folliculitis. A specific type of folliculitis, called pityrosporum folliculitis, is likely the cause of a common skin rash seen in many people who wear Lululemon or other tight-fitting pants to the gym. This type of folliculitis often resembles acne but is distinct in that it causes itching, whereas acne typically does not.
The best treatments for folliculitis depend on the type and cause of folliculitis you have, as well as how mild or severe it is. Mild cases of folliculitis may clear up on their own, and warm compresses can help to soothe skin in the meantime. For more severe or recurrent cases, your dermatologist might prescribe topical or oral medications to clear the infection.
To prevent folliculitis in the future:
- Use a moisturizing shaving cream each time you shave.
- Shave in the direction of hair growth, not against it.
- Shower or change clothes immediately after working out.
- Avoid wearing tight clothing such as leggings, especially when working out, if you begin to develop a bumpy rash.
- Use a skin care routine for your skin type

Dry Rough skin
Rough, itchy, or ashy skin can also be caused by dehydration. Skin becomes dry and dehydrated when its protective barrier is impaired and unable to function properly. An impaired skin barrier will have trouble retaining moisture and keeping allergens and irritants out.
While some people are genetically predisposed to have dry, dehydrated skin, lifestyle factors such as spending lots of time in the sun or exposing the skin to cold wind in the winter can also contribute to a damaged skin barrier.
Dry skin in darker skin tones can sometimes appear to be gray or ashy and often feels rough or bumpy.
Very dry or ashy skin can benefit from twice-daily applications of a good-quality barrier repair moisturizer. As your skin begins to repair itself, you should notice dryness, itching, and flaking diminish, revealing a smoother and brighter complexion. Darker skin types rave about Zerafite Brightening Barrier Cream to treat rough bumps on dark skin and brighten the skin.
Moisturizers to treat rough bumpy skin
To restore proper skin barrier function and healthy hydration to your skin, use a barrier repair moisturizer that has a maltese cross pattern under the microscope which means it can mimic your skin’s natural lipid structure and repair barrier damage.
The best barrier repair creams to treat bumpy rough skin should be chosen based on what other issues your skin has.
If it is red and rough and bumpy, use Zerafite Soothing and Calming Moisturizer.
I it is rough and bumpy and wrinkled use Zerafite Wrinkle Defense Barrier Cream Moisturizer.

Because of this, it is important to combine the proper treatment products with healthy lifestyle habits to maintain soft, smooth, healthy skin.
