Each of the four tools does one job, and they do not compete for the same minutes. The only thing to get right is the order, because some steps need clean bare skin and others need slip.
Morning: drain, then brighten
Start with the roller on a cleansed face, ideally straight from the fridge. Roll from the centre outwards, then down the neck, for about five minutes. This moves overnight fluid and gives skin the flush of extra blood flow. Then place the eye patches; they sit better on skin that has just been rolled and slightly warmed. Ten to fifteen minutes while you get ready, peel, pat in the serum, and go on to sunscreen. If you use a serum or oil with the roller, apply it first for slip; the patches still adhere fine afterwards if you wipe the under-eye dry.
Evening: light, then water, then seal
Cleanse, then dry the face completely. The red light panel goes first, on bare skin, because products on the surface scatter and absorb the light and reduce the dose reaching the skin. Ten minutes at the specified distance, goggles on. On mask nights, the sheet mask comes next: fifteen minutes, off while still damp, and press the essence in. On other nights, go straight to serum. Finish every evening with a moisturiser, which is what keeps the water from the mask or serum in the skin overnight.
How often for each
Roller: daily, morning. Patches: daily or whenever the eyes need it. Red light: three to five evenings a week, consistently, for at least eight weeks before judging. Masks: two or three evenings a week. If you only have five minutes, the roller and patches give the biggest change you can see today; the lamp and masks are the long game.
Two things not to combine
Do not use the roller on skin that is irritated from a strong acid or retinol night. And do not put a sheet mask on directly after red light if the skin is flushed and warm; give it a few minutes to settle so the occlusion does not add to the redness.
