Many of the following ingredients are essential oils and botanical extracts. Even some botanicals and antibacterial agents can cause reactions in sensitive skin types. To find out if you will have a negative reaction, do a small patch test on your forearm before using products on a large area of your body.

Aloe Vera
Aloe vera juice and oil are extracted from the aloe vera plant, which is found mainly in sunny climates. The leaves store large amounts of water. The extract improves hydration and is soothing and healing to all skin types. It is composed of water; the enzymes catalase and cellulose; minerals such as calcium, aluminum, iron, zinc, potassium, magnesium, and sodium; as well as twenty amino acids. It is known for its healing and anti-inflammatory properties. Aloe vera is used safely and successfully as an anti-inflammatory and as a hydrating agent both as an edible ingredient and in topical applications.
Alpha and Beta Hydroxy Acids
The following hydroxy acids are commonly used in cosmetic products:
o citric acid (AHA)
o glycolic acid (AHA)
o lactic acid (AHA)
o malic acid (AHA)
o salycylic acid (BHA)
o tartaric Acid (AHA)
Certain formulations of AHA products can increase cell turnover rate and increase the thickness of the epidermis. The effect depends on the product's pH level or measure of its acidity, the AHA concentration, the AHA vehicle cream or cleanser, as well as how the product is used (for example, frequency and quantity of use, where on the skin it is applied). By speeding up exfoliation, the topical use of hydroxy acids makes skin appear smoother. Lactic acid is commonly found in milk, pickles, and other foods made by bacterial fermentation. Lactic acid can help reduce the effects of photo-aging and can play an important role in the treatment of sun-damaged skin. Glycolic and salicylic acids are my favorite agents for increasing the cell turnover rate and uncovering younger skin. Hydroxy acids are one of the most popular keys to unclogging embedded cellular debris from pores and shedding the outermost layer of dead skin. Consistent exfoliation thins the dead skin that builds up, producing an ongoing vitality in skin texture and quality. If you stop using hydroxy acids, your skin will gradually revert to its normal sluggish turnover rate.
