It’s a fact: Weather extremes are increasing—and changes in humidity and temperature can wreak havoc on the skin.

Cold weather depletes moisture-trapping lipids, causing dryness, itching, and irritation. Indoor heating and air-conditioning also strip skin of moisture. Warmer weather can increase oiliness and acne.

Dr. Loretta’s best defense:

For the most effective moisture replenishment, Dr. Loretta’s formulas incorporate bioidentical lipids and marine peptides. To reduce excessive oiliness without drying the skin, the formulas contain perfectly adjusted pH levels of glycolic and salicylic acids combined with essential oils and marine extracts.
