L’Oreal have a range of skin firming products for the face and neck and Chemist Warehouse has them on sale every couple of weeks!

Well done on the weight loss, great achievement. I’m nearing 50 and also have saggy skin problems. I loved reading the solutions on your question. Fantastic natural fixes. I’ll be tryin the egg white

I just want to say congratulations on the weight loss – that’s amazing!

I would love to know this too as I am currently on a weight loss journey of my own and can see my skin (particularly) on my arms is starting to get very loose..

1. Egg White
Egg whites are a natural astringent and hence work as a good remedy for sagging skin. Its skin-nourishing ingredient hydro lipids help lift loose skin.

Whisk one to two egg whites until you get a foamy texture. Apply it to the face and neck. Leave it on for about 20 minutes and then rinse it off with cool water.
Another options is to add one tablespoon of plain yogurt to one egg white and whisk it. Apply the mixture to your face and neck and leave it on for 20 to 30 minutes before rinsing it off.
You can use either of these remedies twice a week to enjoy firm, radiant skin.
2. Lemon
The vitamin C in lemon helps boost collagen production. This in turn helps restore elasticity to your skin. Plus, lemon has astringent properties that help tighten the skin and reduce wrinkles and other signs of premature aging.

Extract some fresh lemon juice and rub it gently on your face and neck. Leave it on for five to 10 minutes and then rinse your face with water. Do this two or three times a day and follow up with a good-quality moisturizer.
You can also add the juice of half a lemon to a cup of cold water. Splash this mixture on your freshly washed face. Allow the lemon water to air dry on your face. Follow this remedy once or twice daily for best results.

3. Cucumber
To tighten loose and saggy skin, you can also use cucumber. It is one of the best natural skin toners and has a refreshing and rejuvenating effect on skin.

Grind half a cucumber and squeeze it through a strainer to extract its juice. Apply this juice on your face and leave it on until it dries. Rinse it off with cool water. Follow this remedy once daily.
You can also combine one tablespoon each of grated cucumber and plain yogurt. Apply the mixture on your face and leave it on for 10 to 15 minutes. Rinse it off with lukewarm water. Repeat several times a week.
You can also make a face mask with two tablespoons of fresh cucumber juice, one egg white and three to five drops of vitamin E oil. Apply this mask on your face and neck, leave it on for 15 minutes and then wash it off with cool water. Use this mask once a week.

4. Honey
Honey has natural hydrating, antioxidant and anti aging properties that are helpful for treating sagging skin.

Mix two to three teaspoons of honey and a few drops each of lemon juice and olive oil. Apply it on your face and neck, let it dry and then rinse it off with warm water. Do this once or twice daily for best results.
You can also mix together one-half tablespoon each of honey and sour cream. Then mix in one-half teaspoon of turmeric powder. Apply the mixture on your face for 15 minutes. Rinse it off with lukewarm water and then splash some cold water. Use this face mask once a week.

Wishing you well.
