Three ingredients. One of them is hypochlorous acid, the same molecule your own immune system makes. Spritzed onto clean, damp skin it calms the look of redness and irritation and leaves skin feeling clean, comfortable and reset.

This is the spray that started the category, and it is the reason so many facialists keep a bottle on the trolley. It is alcohol-free, pH balanced and made without added fragrance, so it is gentle enough to use morning and night, over makeup, after a workout, or in the days after a treatment.

In a third-party consumer study of 30 participants:

• 100% saw an improvement in the appearance of skin redness after 1 hour
• 100% saw a decrease in the appearance of blemishes after 4 weeks
• 87% experienced immediate relief from dry skin

Carries the National Eczema Association Seal of Acceptance, and is National Rosacea Society Accepted and National Psoriasis Foundation Recognized.

Tower 28 was founded in Los Angeles by Amy Liu, who spent fifteen years in the beauty industry managing her own chronic eczema and being told her only option was clinical products that did not work. The brand is named after a real lifeguard tower on the LA coast, a literal sign of safety. Every formula starts from sensitive skin rather than treating it as an afterthought, and is developed with a medical advisory board of board-certified dermatologists and surgeons. The SOS skincare line carries the National Eczema Association Seal of Acceptance, is National Rosacea Society Accepted and National Psoriasis Foundation Recognized. All products are vegan, cruelty-free and free from added fragrance, and the SOS packaging is made from post-consumer recycled plastic under the brand's Earth-Sensitive Pledge.
