Daily consumption of almonds reduce facial wrinkles

Anti-aging regimens abound but emerging research suggests that one delicious addition to your skincare routine may be in your pantry instead of your makeup kit: almonds. 

A new pilot study wrinkles found that a daily snack of almonds in place of other nut-free snacks improved measures of wrinkle width and severity in postmenopausal women. A larger and longer-term follow-up study is underway. 


In this 16-week randomized controlled trial, 28 healthy postmenopausal women with Fitzpatrick skin type 1 or 2 (characterized by increased tendency to burn with sun exposure) were randomly assigned to one of two groups. In the intervention group, women ate almonds as a snack, which accounted for 20% of their total daily calorie intake, or 340 calories per day on average (60 grams). The control group ate a nut-free snack that also accounted for 20% of calories: a cereal bar, granola bar or pretzels. Aside from these snacks, study participants ate their regular diets and did not eat any nuts or nut-containing products.
Skin assessments were made at the start of the study, and again at 4 weeks, 8 weeks, 12 weeks and 16 weeks. At each visit, facial wrinkles were assessed using high-resolution facial imaging and validated 3-D facial modeling and measurement. “These high resolution cameras allow for 3-D reconstruction of any wrinkles so that they can be mapped for their key characteristics of width and severity. The severity score is a calculation of the depth and length of a wrinkle,” explains  lead researcher on the study. Skin barrier function was also assessed, by measuring sebum production and transepidermal water loss (TEWL). Skin barrier function examines the strength of the skin barrier and how well it protects skin from moisture loss (TEWL) and from harmful irritants coming from the environment.

By the end of the study at 16 weeks, photographic image analysis showed statistically significant improvements for participants in the almond snack group compared to the control group (P<0 .02="" br="">Wrinkle width decreased by 10%
Wrinkle severity decreased by 9%

There were no significant changes in skin barrier function between groups. “Food as a means of promoting skin health – the “health from the inside out” idea – is of growing interest to those looking for options for healthy aging,” says Dr. Sivamani. “It’s also a growing area of scientific research. Almonds are a rich source of antioxidant vitamin E and deliver essential fatty acids and polyphenols. They’re a smart choice for overall good nutrition. And, as seen in this study, almonds may hold promise as a food to include as part of a healthy aging diet, especially for post-menopausal women.”

Study at a Glance:
The Study: 28 healthy, postmenopausal women with Fitzpatrick skin type 1 (always burns, never tans) or 2 (usually burns, tans minimally) were randomly assigned to either an intervention or a control group. Almonds were provided as 20% of total daily calorie intake for the intervention group (340 calories/day on average), about 60 grams. The control group consumed a calorie-matched nut-free snack in place of almonds daily: cereal bar, energy bar or pretzels. All participants were advised not to consume any nuts or nut-containing products over the course of the study (except for the almond snack for the intervention group). They otherwise were advised to continue their usual daily energy intake.

After a four-week dietary wash-out period, participants were randomized to one of the two study groups detailed above. Study visits occurred at baseline, 4 weeks, 8 weeks, 12 weeks and 16 weeks.

Facial wrinkles were assessed using high-resolution facial photography and validated 3-D facial modeling and measurement at baseline, 8 weeks and 16 weeks. Skin barrier function was assessed by measurement of sebum production and transepidermal water loss (TEWL).

Results:
Photographic image analysis showed that the almond group had significant reductions in wrinkle width and severity, by 10 and 9%, respectively, compared to the control group at the 16-week time point (P<0 .02="" br="">

There were no significant differences in sebum production between groups after 8 and 16 weeks.


There were no significant differences between groups in transepidermal water loss (TEWL) from baseline after 8 and 16 weeks.

There were no significant changes from baseline in the skin barrier function (P=0.65) between the almond and control groups relative to baseline after 16 weeks.

Study Limitations
Aging is a long-lasting process so the findings from this 16-week study may be difficult to reproduce and generalize to extended periods of time. Skin-aging is also multi-factorial in nature and although certain groups were excluded (i.e., those with a smoking history), there is variance in aging confounders, such as frequency of UV light exposure and emotional stress, which were outside the scope of the study. This study was limited to cosmetic evaluation, as no measurements were made regarding collagen production. Study did not evaluate disease or younger subjects, so results are limited to otherwise healthy post-menopausal females. In addition, this was a pilot study with a limited number of participants. Future studies should expand to a larger recruitment pool.

ConclusionResults of this pilot study suggest that daily consumption of almonds may play a role in reducing wrinkle severity in post-menopausal women. The outcomes warrant future studies with expanded population groups and additional evaluations for signs of skin aging.skincare.

Large Pores- What One Can Do

Women go to great lengths to hide their large pores. They look for the right makeup primer, foundation, powder, matte products, they look in the mirror every hour, wash the makeup off in the evenings and repeat this all again the next day! Aside from using makeup, they also use scrubs and masks. But in order to solve the issue of large pores on your skin, you need to choose an integrated approach.

What causes large pores and what to do with them
Skin pores produce an oil-like substance called sebum which keeps the skin moisturized and saturated with oxygen. It also helps absorb healthy ingredients from cosmetics. But if the skin produces too much sebum and doesn't get the right care, pores become dirty and enlarged which may cause acne. 

Large pores come about due to a number of reasons. Excess production of sebum is one, which may be caused by bad food, stress, sunlight exposure without sunscreen, the wrong type of skincare or comedogenic cosmetics. A decrease in elasticity is another possible cause. With age, the production of collagen is slowed down, the skin becomes less elastic and the pores look bigger.
Take care when out in the sun as damage due to sunlight exposure can also lead to the destruction of collagen. Genes may also be a cause. In fact, scientists found out that the pores of Asian women do not change much with age, while the pores of Indian women become bigger. And while you cannot change your genes, you can change your approach to skincare and food, ensuring that your skin looks better. So, what more can you do to protect your skin:
1. Reconsider your diet 
Firstly, decrease the production of sebum. You should also reconsider your diet, your skincare procedures and the ingredients of your cosmetics. Be sure to protect your skin from collagen destruction by using sunscreen every day and stop the pores from becoming bigger by moisturizing them regularly, using non-comedogenic cosmetics. This approach won't change your skin type but it will help to make your pores smaller and clearer. If you notice your skin becoming oily after just one hour after morning care, maybe it's because your skin produces too much sebum. 
What you can do:
1. Decrease the number of carbs you eat: Foods that have a high glycemic index, such as sugar, white bread, and white rice can make the skin produce more sebum. Consequently, pores get blocked and this may lead to acne.
2. Add herbs and spices to your food: Opt for cinnamon, oregano, cloves, ginger, and garlic. All this prevents the processes that lead to aging of the skin and the decrease in elasticity.
3. Drink green tea: It contains polyphenols that decrease the production of sebum, helping to reduce acne.
4. Eat more fish and vegetables: These foods decrease the probability of acne. 
2. Clearing and moisturizing
If your skin is prone to large pores it should be moisturized and cleaned twice a day. The remains of cosmetics, dead skin cells and dirt block the pores, leading to a breakout. 
What you can do:
1. Use peels that contain salicylic acid (up to 1%) or glycolic or lactic acid (2-5%) as they stimulate the regeneration of cells, helping to keep pores clear.
2. Don't use scrubs as they contain abrasive particles that can damage the skin and cause inflammation which can lead to enlargement of pores. 
3. Use gels to clear your face as they are better for oily skin than lotions are.
4. Don't wash your face with regular soap. The acidity of soap is 8 to 10 on the pH scale so it can destroy the protective layer of the skin, which will lead to an increase in sebum production. Use products with a pH no higher than 5.5.
5. Wash your face sometime between noon and 4 pm. At this time of day, the skin produces sebum very actively which is why we notice an oily shine in the middle of the day.
6. Use sunscreen as if you don't, the UV-light will destroy the collagen in your skin making it less elastic.
7. Use a water-based cream or gel as they moisturize the skin without blocking the pores. 
3. Choose safe cosmetics
Cosmetics are comedogenic if they contain ingredients that can block pores like wax, oils, talcum and other similar components. Skin with enlarged pores requires cosmetics that decrease the production of sebum. Look out for useful components in cosmetics like Nordihyroguaiaretic acid, NDGA, and sarcosine, which reduce the production of sebum. Furthermore, it's better if you do not buy cosmetics that contain:
1. Talcum as it clocks pores. You're better off using mineral based products.
2. Alcohol dries out the skin and disrupts the natural process of removing dead skin cells.
3. Mineral oil is a cheap, easy comedogenic component of many cosmetic products.

Some known causes of Acne

 Most people are affected by acne sometime of other in their lives. It could be due to oily skin, growing up, some say when one eats too many oily foods , you get acne! Teen girls find it difficult to cope with acne, as it affects their looks, but it shows some underlying problems.

What is acne?
Human skin has follicles or pores in them through which hair comes out. The accumulation of  sebum within the pores of the skin can sometimes clog these pores. When this accumulates, dead skin cells also get stuck in it and results in a swelling, which takes the form of a pimple like a crest due to bacterial infections. This condition is most prevalent among adolescents due to rapid hormonal changes in the body, although many adults and adolescents have also reported this problem.

Some known causes for acne-
 1) Medications- At times over the counter medicines, containing topical corticosteroids, bromide and use of recreational drugs like marijuana and cocaine can lead to the occurrence of acne as a side effect.

2) Genetics- Some genes are more prone to be affected by this skin problem.

 3) Fat and iodine rich diets- Research shows that excessive oil consumption as well as having foods rich in fat can cause acne problems. Also if you consume iodine in large quantities or for a long time, it results in irritation of the skin pores giving rise to acne.

4) Excessive use of cosmetics-  Excessive use of cosmetic products can cause issues by blocking the pores within the skin and  may induce acne.

5) Hormonal imbalances- This is probably the most common reason cited for acne as adolescents tend to be afflicted by this problem. In many cases acne goes away on its own after sometimes although in other cases it does stay. In adults, especially women it has been noticed that certain hormonal changes in the body may act as acne triggers. Some of the examples of hormonal imbalances may be:a) excessive androgen in women and men.
b) hormonal changes due to poly-cystic ovarian syndrome
c) high testosterone levels in women
d) PMS triggers in adolescent women, and hormonal changes due to periods.
e) Some medication or steroids present in it =, can cause hormonal changes.

6) Diet- Diet-Foods having high glycemic index can aggravate acne.
