Can using multiple skin products increase my skin cancer risk?

Question

Hi doctor,

I have been using all kinds of skin products to treat the dark spots on my face.

Is this harmful to my skin?
I started using sunscreen and moisturizer, which I was told are essential for the skin. But I am scared it will cause trouble later in my life. What type of activity can cause skin cancer?
How can I protect my skin from skin cancer?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Many risk factors for melanoma (a type of skin cancer) have been identified. The most important risk factor is exposure to sunlight, particularly ultraviolet-B (UV-B) radiation. UV radiation causes multiple genetic changes that lead to the malignant transformation of melanocytes.

Cutaneous nevoid melanomas of the head and neck are significantly more likely to occur in people with high levels of total sun exposure. Conversely, melanomas on the trunk tend to develop in people with lower levels of ambient sunlight exposure but who also experience intense but intermittent levels of recreational exposure on the chest and back. Sunburns early in life, exposure to UV radiation from tanning beds, and UV-A therapy are other factors in the development of melanoma.

As in the case of familial atypical multiple mole and melanoma (FAMMM) syndrome, an autosomal dominant disorder characterized by the presence of multiple large moles of variable size and color, patients who have at least one affected first-degree relative have a higher likelihood of developing malignant melanoma. The CDKN2A (p16) chromosomal mutation is the most commonly isolated genetic culprit. Carriers of two or more of the melanocortin-1 receptor (MC1R) variants on chromosome 16q24 have a two-fold greater risk of melanoma.

Minimizing ultraviolet light exposure by limiting the time spent in the sun during the peak hours, using sunscreen, and wearing protective clothing is the most effective primary prevention strategy to reduce the incidence of cutaneous SCC (squamous cell carcinoma, a type of cancer) and its precursors (actinic keratoses) in individuals at risk.

Behavioral interventions have been shown to increase sun protection behaviors in children, adolescents, and young adults. However, there is little evidence that such interventions are associated with a reduction in the incidence and outcomes of skin cancer.

Intakes of total vitamin A, retinol, and some carotenoids (alpha-carotene, beta-cryptoxanthin, lycopene, and lutein/zeaxanthin) were associated with a modest reduction in cutaneous SCC risk. I suggest sending me a picture of your skin tone so that I can suggest a regimen accordingly.

I hope that you get your answer.

Please let me know if you want some help.

Thank you.
