Scarlett Johansson Alters Magnesium Regimen After Spray Left Feet Dry

Actress Scarlett Johansson, known for her roles in the Marvel Cinematic Universe and the upcoming *Jurassic World Rebirth*, recently changed how she incorporates magnesium into her at-home self-care. The adjustment follows her experience using a magnesium spray that she says dried the skin on the soles of her feet. The change was reported in a Miami Herald feature published on August 22, 2026.

Johansson now takes magnesium in oral supplement form each night as part of a wind-down routine aimed at improving sleep, recovery, and overall nervous-system health. She pairs the supplement with a magnesium foot soak during her pedicures, followed by a salt scrub, nail care, moisturization, and polish. In addition to magnesium, she supplements with vitamins C and D, calcium, a B-complex, and omega-3 fatty acids, citing a perceived depletion linked to recent breastfeeding. Her nightly sleep environment includes a white-noise machine, closed blinds, and a cool, dark room.

The shift from spray to soak was prompted by the spray’s drying effect on her feet, which she described as uncomfortable. Johansson indicated that the foot soak provides the same magnesium benefits without the skin irritation, allowing her to maintain the broader benefits she attributes to magnesium—namely better sleep quality and faster physical recovery.

Johansson’s public discussion of her magnesium regimen reflects a growing trend among celebrities and the general public to use magnesium for sleep support and muscle recovery. She notes that many people are now taking magnesium, highlighting its perceived role in digestion and overall wellness. Dermatologists referenced in the article suggest that topical skin products may have a larger impact on skin health than internal supplements, underscoring the importance of balancing both approaches.
