Yogurt is a product of unique aroma and quality containing live bacteria. These qualities arise from culture strains used in the making of yogurt – lactobacillus bulgaricus and streptococcus thermophilus - organisms, which curdle the milk. Yogurt is made when lactic acid ferments in the fresh milk when heated at low temperatures. At this temperature, valuable organisms remain alive.

Many people believe that yogurt originated in Bulgaria. Historical data shows that the Thracians who lived in the southeastern part of Europe within present-day Bulgarian boundaries may have discovered it. Its origin is connected with the sheep breeding that was very popular on these lands at the time of the Thracians. Plentiful fresh milk was used in the production of various milk products, including yogurt. Depending on the type of fresh milk used, yogurt can be cows, sheeps, water buffaloes milk or a mixture of any or all of these. All types of yogurt, regardless of what type of milk is used to make it, contains live bacteria and natural oils, which are known to balance skin oil and moisture levels. 

Yoghurt is an extremely healthy skincare product for both body and face. It has a revitalizing and anti-aging effect on mature and stressed skin. Yogurt is a rich source of vitamins and mineral salts, including minerals, such as calcium, potassium, magnesium, and phosphorus. Real yogurt is the key natural ingredient for traditional facial masks and skincare products.

Yogurt can also be used as a natural after-sun soothing lotion that aids the healing of sunburns and allergic irritations of skin on the face and body. It has a strong whitening effect, and is traditionally used in combination with aspirin to create facial masks that are said to improve and brighten the complexion. Yogurt is also said to be beneficial in the treatment of skin defects and scars. Pure natural yoghurt has a pH regulator compatible with all skin types, but is known to be particularly good at relieving and hydrating dry skin. Natural yogurt protein soaps and shower gels are becoming very popular with consumers opting for natural ingredients in beauty care products.

When it comes to using yogurt in beauty preparations, technologically, the process of using real yogurt instead of dehydrated yoghurt powder is difficult and expensive. Using yogurt in cosmetic products is a challenge because of the live bacteria, which need to be preserved. Still, it is agreed that it is worth all efforts to maintain the natural proteins preserved in real yogurt extracts as they have immense soothing and revitalizing qualities. The only possible way for making the best of its beneficial live protein effects is using yogurt as a base and adding other ingredients to build up skincare formulas. Traditionally preferred combinations are vegetable oils, wheat bran, fresh lemon juice, and fuller’s earth. These combinations are in fact popular facial and hair care homemade masks, which have become the basis for numerous skincare product lines produced by cosmetics companies.
