1-2 Days - What you see is about 20-40% darker, bolder and more solid that what your healed result will present. Under the pigment, the skin is red and pigment has been deposited into the layer of skin containing dead skin cells; combined giving the appearance of darker color. There may be minimal swelling but because typically the eyebrow area does not retain much fluid, swelling will be limited. The top layers of skin will begin to shed on about day 3-5, and you will see a loss of color. This is normal, and the pigment that was deposited superficially will come off with the skin it is embedded within. DO NOT HELP IT! Let it peel on its own. If you pull the skin off, you will remove 'plugs' of dermal pigments as it has not detached itself completely at this point.
3 Days - Your eyebrows may begin to itch and the pigment may appear somewhat raised. Don't scratch them.
4-6 Days - The skin is now in the throes of rapid exfoliation and if left alone, will shed evenly. The color under the exfoliating skin will continue to appear light until the epidermis takes on its more transparent characteristics.
Days 14-21 - the skin will continue healing underneath, pushing the colored pigment to the surface. Over the 5th and 6th week the colour will change due to the tissue repair and its position between the epidermis and dermal layer. The redness will soften and the richness of the brown will show though, right now it's clouded from the new heal but it will get darker as it shows though the skin. I've notice colours getting richer as they age in the skin up to 3 months.
30-40 Days - Now is the time to critique your brows as you have had a full cycle of cellular regeneration in which the tattoo has now become part of the dermis, seen under the epidermis.
