🔒 100% Authentic Revlon – sourced from authorised distributors, backed by our Money Back Guarantee.
A 70ml bottle of mixing developer at 1.2%, 4Vol — the low-strength version for toning, refreshing existing colour, or gentle lightening. This is the stabilising part of the Revlonissimo system; you'll mix it with the colour cream at a 1:1 or 1:2 ratio depending on what you're doing.
4Vol opens the cuticle just enough to let colour deposit without aggression. Use it if you're maintaining blonde, adding warmth to mid-tones, or want the gentlest possible lift — skip it if you're going more than one or two shades darker.
