Holla, hari ini admin nak share vitamin yang bagus untuk kulit, sila pastikan daily skincare uols mengandungi Vit A, Vit B3, Vit C, Vit E and Vit K, bukan bahan kimia semata. Vitamin-vitamin tersebut biasanya dari tumbuhan yang dah diekstark dalam bentuk oil dan mempunyai fungsi-fungsi nya yang tersendiri. happy reading uols.
1. Vitamin A for wrinkles
❤❤ Best overall age-fighter
Find it in: OTC lotions, night creams (vitamin A derivatives are known as retinoids), and prescription products
Proven to: Reduce wrinkles, fade brown spots, and smooth roughness. "There are more than 700 published studies on retinoids—they're tried-and-true ingredients. Anyone who wants younger-looking skin should use one," says Doris Day, MD, assistant clinical professor of dermatology at New York University Langone Medical Center
2. Vitamin B3 for redness
❤❤ Boosts hydration to reduce redness
Find it in: Lotions, creams, and serums. It's often called niacinamide on the label.
Proven to: Increase production of ceramides and fatty acids, two key components of your skin's outer protective barrier. "As that barrier is strengthened, skin is better able to keep moisture in and irritants out—making B3 a great ingredient if your complexion is dry or sensitive," says Leslie S. Baumann, MD, director of the University of Miami Cosmetic Medicine and Research Institute. In one study, a moisturizer with niacinamide improved the flushing and blushing of rosacea, a common condition that can worsen with age. Another B3 skin care benefit: It inhibits the transfer of pigment to skin cells, minimizing dark spots.
3. Vitamin C for spots
❤❤ All-around anti-ager
Find it in: Moisturizers formulated to keep vitamin C stable (opaque, airtight containers are ideal). Look for C near the middle of the ingredients panel to help ensure the 5% or higher concentration needed to see skin care benefits, advises Hema Sundaram, MD, a dermatologist in the Washington, DC, area.
Proven to: Mop up the free radicals that trigger wrinkling, sagging, and other aging changes. Vitamin C also helps smooth and firm skin and fade brown spots. In one study, women who treated sun-damaged skin with a C cream for six months saw significant improvement in fine lines and discoloration. Though the benefits of retinoids (see vitamin A) and vitamin C sound similar, using both delivers more complexion perfection. "Skin aging occurs in various ways, so you need multiple forms of defense and repair," says Dr. Lupo.
4. Vitamin E for moisture
❤❤ Eases dryness and bolsters skin's UV defense
Find it in: Sunscreens and after-sun products. The best anti-aging products contain at least 1% vitamin E, so it will be listed near the middle of the ingredients panel.
Proven to: Quell dryness by helping skin retain its natural moisturizers. Also, vitamin E's potent ability to neutralize damaging free radicals has earned it the moniker "the protector." A slew of skin care studies document its superstar status. In one, E significantly reduced the number of these unstable molecules created after exposure to cigarette smoke. Others show that when it's used before UV exposure, skin is less red, swollen, and dry.
5. Vitamin K for dark circles
❤❤ For younger, brighter eyes
Find it in: Eye creams that also contain retinol.
Proven to: Possibly help lighten under-eye circles. Fragile capillaries that allow blood to leak into skin are considered one cause of under-eye circles, and vitamin K (aka phytonadione) may put the skids on this seepage by controlling blood clotting. Daily use of a K cream significantly lightened circles after 4 months in one study, but because the cream also contained retinol, researchers aren't sure which ingredient deserves credit for the improvement—retinol alone thickens the translucent under-eye skin (making it harder to see the dark blood vessels below) and lightens melanin that makes circles more prominent. Still, it can't hurt to try a cream that contains vitamin K and retinol; according to Dr. Baumann, the retinol may enhance K's ability to penetrate skin and knock out darkness.
