Oral Sunscreen: Are sunscreen pills effective for skin protection?

Oral sunscreens, often marketed as “

sunscreen pills

,” are dietary supplements containing antioxidants and other compounds that claim to provide protection from UV-induced skin damage. While they may offer some benefits as an adjunct to topical sunscreens, they are not a standalone replacement for traditional sun protection measures.
A study by the National Institutes of Health has shown that ingredients like Polypodium leucotomos, a fern-derived antioxidant present in many oral sunscreens, can reduce markers of sunburn and

UV damage

when taken at appropriate doses. However, the level of protection is relatively modest—comparable to SPF 3-5.

Is oral sunscreen better than topical sunscreen?

According to Dr. Mikki Singh, founder, medial director, Bodycraft Clinics, “Oral sunscreens can provide systemic protection, which might benefit areas less effectively covered by topical sunscreens (e.g., scalp, ears). These pills do not physically block or absorb UV radiation like topical sunscreens. Instead, they mitigate the cellular damage caused by UV exposure. Oral sunscreens cannot substitute for broad-spectrum topical sunscreens (SPF 30+), which directly block UV rays. They do not protect against UVA/UVB rays directly and must be combined with other protective measures like wearing protective clothing, seeking shade, and using physical sunscreens.”

Should you switch to oral sunscreen?

Oral sunscreens can be a valuable addition to your

sun protection routine

, particularly for individuals with sun-sensitive conditions (e.g., polymorphous light eruption or melasma). However, they should always be used as a complement to topical sunscreens, not a replacement. Educating patients about proper sun protection strategies remains essential.
