Aspirin is great for your skin. Basic function of it is being an analgesic and antipyretic, but more importantly, as far as skin care, it is its anti-inflammatory power. This is important when it comes to treatment of acne and other inlammation processes on the skin.
Aspirin contains acetyl-salicylic acid AKA Beta Hydroxy Acid, widely used in cosmetics as it is able to slough off skin cells thus preventing the clogging of pores.
It is a powerful ingredient that cleanses skin and treats the the cause of acne.
It is pretty cheap and almost everyone has it around the house.

Rose water is astringent, anti-inflammatory and antiseptic, and can be used as a facial cleanser or as a toner

Honey check my post on Honey

Aspirin is actually a form of Beta Hydroxy Acids or BHA’s, which are found in many skin creams and work by exfoliating the dull, dead layers of skin, revealing fresh new skin underneath. Over time, BHA’s can help clarify skin tone and promote healing of blemishes. However, do not use the aspirin mask if you have a sensitivity to BHA’s or if you have very sensitive skin, or obviously if you are allergic to aspirin!”

Why does it work? taken from Essential Day Spa

To make the mask you'll need

Rose Water

Aspirin (3 or 4 tablets)

Honey

Alcohol free toner

Moisturiser I use Neutrogena Healthy Skin Anti-Wrinkle cream (until I find one a natural one that I can make on own)

1) Take around 2-3 tablets of aspirin *if u can find coated then simply dissolve them in a few drops of water, if not then I crush the tablets (it should be grainy not powdery) instead then add a few drops water.*

2) I would suggest adding drops of water at a time to get the right consistency you don’t want it too runny as you still have to add honey!

3) Add a 2 squirts of Honey onto the aspirin. After wards, mix the mixture until the aspirin is coated with the honey.

4) Before applying the mixture I cleanse my face with rose water by soaking a cotton pad with rose water and going over my face.

5) Start applying the mixture on your face. Make sure you avoid the eye and nose areas (specifically nostrils!) Apply and spread the entire mixture on your face. Leave it on like a mask for 10 MINUTES.

As you are washing it off, take advantage of the grainy texture of the aspirin and LIGHTLY exfoliate your skin. This will get the dead skin cells off your face, and polish your skin to leave it glowing
After having dried your face dab some toner on a cotton ball and wipe your entire face in a circular motion. The toner will not only take off the gunk that the cleanser left behind (like makeup and dirt) but it will also constrict the pores, making them appear smaller and less visible. Finally apply moisturizer on your face and VOILA you’re done.

I use this mask once a week as I have sensitive/combination skin type.

As I mentioned earlier in my post you can add other ingredients such as yoghurt, which is good for dry skin, you can search the net there are lots of different ways but this is the one I tried and works for me and hope you find one that works for you.
