Pigmented skin-care compositions
View Patent ↗A pigmented skin care composition including a dermatologically acceptable carrier and at least a first and second interference pigment. The composition according to the invention is useful in improving the appearance of the skin and in particular in reducing the appearance of skin discontinuities.
1. A skin care composition comprising:
a dermatologically acceptable carrier;
a plurality of interference pigments, wherein the summation of all the interference pigments in the composition having a particle size between 2 μm and 75 μm is equal to or less than 3% of the composition by weight;
wherein the composition has a redness reduction index (RRI) of less than −11.5;
wherein the composition has a healthy skin color change value (HSCCV) of less than 3;
and wherein the plurality of pigments comprise at least a first and second interference pigment, wherein the first interference pigment has a hue angle (h) between 185°-215° and wherein the second interference pigment has a hue angle (h) between 80°-95°.
2. The skin care composition of claim 1 , wherein the summation of all the interference pigments in the composition having a particle size between 2 μm and 75 μm is between 1% and 3% of the composition by weight.
3. The skin care composition of claim 2 , wherein the composition has a redness reduction index (RRI) between about −12.0 and −16.0.
4. The skin care composition of claim 1 , wherein composition has a HSCCV of between 0.5 and 2.5.
5. The skin care composition of claim 4 , wherein the chroma of the composition is greater than 3.5.
6. The skin care composition of claim 5 , wherein the chroma of the composition is between 4.0 and 15.0.
7. The skin care composition of claim 1 , wherein the ratio of the percentage of the first interference pigment to the second interference pigment is in the range between 20:80 and 80:20.
8. The skin care composition of claim 7 , wherein the chroma of the composition over the entire range is less than 8.5.
9. The skin care composition of claim 1 , wherein the skin care composition additionally comprises at least one skin care active.
10. The skin care composition of claim 9 , wherein the skin care active is selected from the group consisting of depigmentation agents and skin-lightening agents; keratolytic agents; anti-acne agents; anti-aging actives and anti-inflammatories.
11. The skin care composition of claim 6 , wherein the composition has a multi-angle Δa* (MADA) value of greater than −4.0.
12. The skin care composition of claim 11 , wherein the composition has a MADA value of between −3.5 and 0.3.
