About this formula
A pH-balanced foam cleanser formulated for fragrance-reactive and seborrheic dermatitis-prone skin. Five ingredients. No fragrance, no essential oils, no emulsifiers that disrupt the acid mantle. Refill pouch — fits the Starter Kit aluminum vessel.
Full ingredient list: Aqua, Glycerin, Sodium Cocoyl Glycinate, Panthenol (pro-vitamin B5), Allantoin.
Why each ingredient is here: Glycerin humectant; Sodium Cocoyl Glycinate is a coconut-derived amino acid surfactant with a skin-neutral pH of 5.5–6.5 (no irritating sulfates); Panthenol supports barrier repair; Allantoin calms post-cleanse sensitivity.
What people say
★★★★★
"I've been dealing with seborrheic dermatitis for six years. Every cleanser I tried — including 'dermatologist recommended' ones — had fragrance or essential oils buried in the ingredient list. Derrin's cleanser is literally five ingredients. I can see exactly what I'm putting on my face. Two months in, no flare."K.M., r/SebDerm waitlist
