How does bulimia affect the skin?
Bulimia can have several side effects on the integumentary system, that is, the skin, hair, and nails, including: (2)
- Brittle and dry hair and nails
- Infections around the nails and cuticles
- Discoloration of the extremities from poor circulation
- Russell’s sign - calluses on the knuckles from repeated induced vomiting
- Abnormally dry skin and membranes
- Slow wound healing
- Fine body hair
Bulimia and acne
Frequent vomiting from bulimia can result in dehydration that may lead to an abnormal dryness of the skin. This excessive dryness is caused by a decrease in skin surface lipids, which occurs between 2-4 weeks after consistent nutrient restriction and sees sebum, or oil, production decrease by as much as 40%. (3)
Wait, what? How can less sebum and dry skin result in acne? Dry skin caused by bulimia can contribute to acne in several ways:
- By causing an excess of dead skin cells, which clogs the pores
- By making pores more likely to break open, allowing acne-causing bacteria to penetrate deeply into the skin
- By triggering the production of excess sebum, or oil
Vitamin and mineral deficiencies often seen in people with bulimia may also be linked to the development of acne: (4)
- Zinc: Believed to have antibacterial and anti-inflammatory properties, as well as decrease oil production on the skin
- Vitamin A: This appears to counter the actions of several types of bacteria are known to have a big role in the development of acne
- Vitamin D: Those with acne have lower levels of vitamin D, which may block acne-causing bacteria from affecting skin cells
Treatment for bulimia acne
Treatment of the underlying eating disorders often resolves skin issues like bulimia acne. (3)
Recovery from bulimia can be a long journey, and some patients experience additional acne breakouts, once they start treatment. This could be due to the sebaceous glands reactivating in the skin, leading to an overproduction of oil, resulting in blemishes. But there are things that can help heal stressed, acne-prone skin during the recovery process.
Let your skin heal
It can be tempting to pop, squeeze, or pick your acne, but blemishes will take longer to heal and may result in acne scars. Plus, touching your face frequently can transfer bacteria to your skin, causing new flare-ups. (5) Obsessive-compulsive tendencies often go hand-in-hand with bulimia and can compel repetitive behaviors like this. But the right treatment approach to bulimia can help break accompanying habits and address the underlying causes.
Find the right treatment
Acne can be successfully treated with topical antibacterials, benzoyl peroxide, or azelaic acid as a single therapy or in a combination. Combination antibacterials, like zinc with erythromycin, are also effective treatments, as they address zinc deficiency often seen in people with eating disorders. (6)
See a dermatologist
A dermatologist can be a key member of a treatment team for those in bulimia recovery. (7) These specialists can identify the skin problems resulting from your disordered eating behaviors, determine whether your skin barrier is damaged through nutrient deficiencies, and recommend an appropriate course of treatment. This can include topical creams, gels, or lotions, oral medications, or dietary supplements, as well as a skincare regimen.
Skin care tips
Never skip sunscreen
Some of the active ingredients in acne treatments, such as benzoyl peroxide and salicylic acid, can make skin more sensitive to the sun. So it’s important to apply sunscreen with at least SPF 30 every day. (5) Sunscreen will also help reduce inflammation and pigmentation marks left behind by acne.
Repair the skin barrier
Be kind to your skin. If it’s dry and dehydrated, you will irritate it further with abrasive scrubs and cleansers, or harsh astringents. These can all strip the skin of its natural moisture. Other things you can do to repair the skin barrier include:
- Avoiding scrubbing the skin
- Applying products with your fingertips
- Using gentle, alcohol-free products to avoid further drying out the skin
- Washing and rinsing with lukewarm water
- Applying a light non-comedogenic moisturizer after cleansing
- Choosing products with soothing and hydrating ingredients, such as hyaluronic acid, niacinamide, and ceramides
- Drinking plenty of water to stay hydrated
