Salicylic acid is recommended for oily skin, acne or blackhead prone skin, and red or inflamed skin. Since I have all of those, I use white willow bark extract quite a bit.
I like to use it in a toner, moisturizer, and cleanser. I add 0.5% white willow bark to the cool down phase of my product - after dissolving it in some warm water. You can go as high as 1.0%, but it can make you sun sensitive and red, so start low and move your way up as you determine how you like it. And start by using it in one product before including it in every facial product you use. I started by using it in my toner, then moved on to including it in my cleanser. I have since started including it in my night-time moisturizer as I don't want to get too sun sensitive.
Let's see how this works in a facial cleanser, specifically a very oily skin foaming facial cleanser (click here for that recipe, or click here for a version for less oily skin). White willow bark is especially good for people with really oily hair or skin, so it is a fabulous inclusion for facial products.
FOAMING FACIAL CLEANSER FOR NORMAL TO OILY SKIN CONTAINING WHITE WILLOW BARK
10% aloe vera
10% hydrosol of choice
3% PEG 7 olivate (water soluble olive oil)
10% SMC Taurate (liquid)
8% Amphosol CG (coco betaine)
3% hydrolyzed protein
0.5% preservative (Liquid Germall Plus)
1% fragrance or essential oil (optional)
0.5% white willow bark extract
Mix together. Package in foamy bottle. Rejoice.
For very oily skin, consider using rosemary as your hydrosol. For normal to oily skin, lavender or orange blossom is very nice. For dry skin, add up to 3% water soluble oil and consider using a hydrosol good for dry skin.
For all skin types, feel free to change the SMC Taurate surfactant for another surfactant your skin likes - do not change the coco betaine as it thickens the mixture slightly and creates a milder cleanser than just the SMC Taurate or other surfactant alone.
And consider using other extracts. Rosemary would be great for oily skin, cucumber for oily or green tea for all skin types, or chamomile for skin that needs some serious soothing.
Consider using white willow bark in shaving products, like shaving lotion, a post-shaving lotion or spray, a shaving bar, or a beard conditioner. It will help prevent ingrown hairs as well as help with redness and inflammation. (In the shaving bar, just dissolve the extract into the panthenol and hydrolyzed protein. If you're using liquid extract, then you can just add it to the cool down phase).
