Medical experts and dermatologists have provided guidance on managing skin pigmentation and the physiological effects of stress on skin health. Initial discussions focused on the prevention and management of pigmentation issues such as melasma, solar lentigines, and post-inflammatory hyperpigmentation. Specialists emphasized the necessity of consistent daily photoprotection, noting that while sunscreen is a primary tool, pigmentation is also influenced by hormonal, inflammatory, or genetic factors. Recommendations included using facial sunscreens with color to protect against visible light and monitoring lesions for irregular changes in size, shape, or color.

Subsequent expert commentary expanded on the difficulty of treating specific conditions, noting that while freckles and age spots may respond well to laser therapy, melasma remains difficult to manage due to its hormonal basis. Specialists also addressed the impact of psychological stress on the skin, describing ‘overstimulated skin’—a condition characterized by increased sensitivity, redness, itching, or burning caused by stress-induced inflammatory processes. 

Recent clinical guidance has detailed specific pharmacological approaches to melasma. Hydroquinone is identified as a primary treatment for inhibiting pigment growth, though experts warn of risks including dermatitis and ochronosis, a potentially permanent dark-blue pigmentation. Consequently, azelaic acid is noted as an effective alternative that selectively targets abnormal pigment cells. Other active ingredients include kojic acid, retinoids, niacinamide, and salicylic acid. Dermatologists also suggest that melasma management may benefit from antioxidant substances or oral photoprotectors to complement topical sunscreens. Experts emphasize that melasma can be categorized into epidermal, dermal, mixed, or excess melanocyte types, the latter being more common in individuals with darker skin tones.
