Though my skin has lightened dramatically... I still don't have the yellowish/orangish undertone that a majority of the people on my moms side of the family have. My undertone shows that I'm clearly still of black descent but with light brown skin. There undertone makes you wonder if they are mixed with something else. Is there anyway to change my undertone?

Have you tried toners or any hydroquinone creams? Hydroquinone is great for skin toning; I used it for my acne scars and it cleared the scars and also, toned out the complexion ot an even color with a yellow undertone. Toners are mild and it would take several months to work. Hydroquinone on the other hand takes about 2 weeks maximum. Well then again, it is different for each individual. I would suggest using Hydroquinone 4% if it's only the undertone you are worried about.

Hope this helps!;)

Thanks. But I'm on a natural skin lightening journey. Plus for some reason I've only had allergic reactions with Hydroquinone. Never any positive experiences. Lol. But I WILL look into a toner! Thanks!

I have heard of some toners that can help brighten the skin, I don't know which are the best brands though. I'm unsure what can permanently make the skin more yellow, but a good bronzer should help your skin look more yellow/golden. People usually have red, olive, golden, neutral or a combination of undertones, so maybe this is what it is?

"If your veins appear to be bluish in color then you fall into the cool category. This also means your undertone is on the blue or pink side of the color spectrum. Now If your veins appear green then you fall into the warm category"

WARM
Warm is for skin tones with a yellow, ruddy or peachy complexion. Hair color can range from dark brown to dark blonde to dark auburn. Eye color is usually brown, hazel, or darker blue. This skin tone tans well and usually does not burn. If you look at the underside of your arm, your veins may have a slight greenish tint if you can even see them at all. You look better in warmer colors, gold jewelry, and ivory instead of white.

GOLDEN
Golden is for a deep, rich yellow skin tone, like a sheet of gold. Hair color can range from darker medium brown to a buttery blonde. You have very golden highlights in your hair. Eye color can be blue, hazel, green or a lighter shade of brown with some gold specs. This skin tone tans very easily and does not burn. If you take a piece of paper and hold it close to the underside of your arm, it should reflect a yellowish or golden tint upon the white paper. You definitely look better in gold jewelry than silver. The gold picks up the highlights/golden color in your hair and skin. You may also notice that wearing black close to your face may take some of your color away and make you appear washed out.

COOL
Cool is for those with pinkish or soft red undertones. Hair color can range from black to dark red to platinum blonde. Eye color is usually light as in blue or green. If you are African American, then your eye color will be very dark brown, almost black . Cools usually burn first and may take along time to achieve a tan. Quite a few won't tan at all. If you look at the veins on the underside of your arm, they will appear bluish. Cool skin tones look better in silver jewelry, white instead of ivory and bolder colors close to their face.
