Skin Lightening Ingredient Dictionary

Hydroquinone is the most effective skin lightening ingredient to decrease melanin pigment production. However, due to safety concerns, hydroquinone is now only available by prescription.

These are the top 10 tyrosinase-inhibiting skin lightening ingredients to lighten dark spots on the skin:

1. Arbutin
2. Artemisia Capillaris
3. Bilberry extract
4. Cysteamine
5. Hexylresorcinol
6. Hydroquinone
7. Kojic Acid
8. Licorice extract
9. Resorcinol
10. Tranexamic acid

Niacinamide is also a wonderful ingredient to lighten skin, but it is not a tyrosinase inhibitor like the skin lightening ingredients on the above top 10 list. Niacinamide is an anti-inflammatory ingredient and a PAR-2 blocker.

Skin lightening ingredients treat hyperpigmentation conditions such as:

• Melasma
• Post inflammatory hyperpigmentation
• Dark spots

Skin whitening, lightening, brightening, or skin bleaching ingredients work best when different categories of ingredients that target the skin pigment melanin are used together in the same skin care routine.

You should choose an ingredient from the tyrosinase inhibitor category and from two other categories to include in your skin care routine to treat melasma or to treat hyperpigmentation.

1. Anti-Inflammatory Ingredients
2. Antioxidant Ingredients
3. Exfoliants
4. PAR-2 Blockers
5. Retinoids
6. Tyrosinase Inhibitors

The prescription medication for melasma called Tri-Luma® is an example of a melasma cream that contains ingredients from 3 different skin lightening categories.

It has an anti-inflammatory corticosteroid, a tyrosinase inhibitor, and a retinoid. Dermatologists call this a Triple Combination Cream and it is the gold standard of prescription melasma creams.

You can combine ingredients from different classes of skin lighteners in your routine to mimic this triple combination cream. Just make sure you have at least 3 of the categories discussed above in your routine and that the products all increase the effectiveness of each other. Let us help you build a skin care routine and shop for products using our skin type.

Skin lightening ingredients lighten dark spots on the skin caused by an increase in skin pigment. These skin conditions will benefit from skin lightening ingredients:

• Age spots
• Dark spots from acne
• Discoloration due to hormones
• Hyperpigmentation
• Melasma
• Postinflammatory hyperpigmentation (PIH)
• Uneven skin tone

The goal is not to whiten your skin but to lighten the dark spots so that your complexion and skin color is the same all over your face. This is particularly important when treating dark spots on black skin.

Skin lightening ingredients can inactivate each other and the moisturizer and cleanser you choose affect how well skin lightening ingredients work. Every product in your routine matters!

To build an effective hyperpigmentation skin care routine you should choose products according to what your Baumann Skin Type.
