October 14, 2026 – PRESSADVANTAGE –
Lenox and Sixteenth, a Miami Beach skincare brand, is outlining how mandelic acid and peptides can fit into a three-step skincare routine as the wet season officially ends in South Florida on October 15, according to the National Weather Service in Miami. The brand notes that humid weather can make heavy formulas feel uncomfortable, and lightweight textures can keep evening care manageable during the seasonal transition. The guidance targets Miami Beach consumers as they head into the drier months.
The forecast office reported that Miami International Airport tied its hottest summer on record in 2026, with 83 days at or above 90 degrees. Its summary also noted that the first noticeable cold front typically brings cooler, less humid air in early or mid-October, although summer-like heat and humidity often linger well into that month.
Dark spots and uneven texture can remain visible after a breakout fades. If a routine doesn’t address those concerns, targeted exfoliation may help create a smoother appearance.
Mandelic acid is an alpha hydroxy acid derived from bitter almonds. According to a dermatology column by Lily Talakoub, M.D., in MDedge Dermatology, it is one of the largest in its class and penetrates the skin slowly and uniformly. The column adds that it can be used cosmetically on all skin types, including sensitive skin and skin of color.
The brand describes mandelic acid as a gradual exfoliant for uneven skin texture and post-breakout marks. Because the Laser Serum Triple Acid Concentrate combines mandelic acid with lactic acid and glycolic acid, its overall effect reflects all three acids rather than mandelic acid alone.
Peptides are short chains of amino acids used in products designed to support firmer-looking skin. In a June 2026 article reviewed by cosmetic dermatologist Shasa Hu, M.D., the University of Miami Health System explained that peptides added to other skincare ingredients can signal the skin to repair itself, which encourages collagen or elastin production. The article described signal peptides, the most common type in skincare products, as having the strongest evidence for smoothing fine lines, and it advised treating peptides as supporting ingredients alongside other proven ones.
The brand recommends using the Laser Serum as the evening resurfacing step, followed by its Soft Landing Smoothing Peptide Moisturizer to replenish hydration and support the skin barrier. This sequence gives each product a distinct role without introducing another exfoliant. Broad-spectrum sunscreen the next morning completes the three steps.
The brand says several factors can guide product selection. Anyone already using retinoids or other exfoliating acids may use them on nights when they do not apply the serum. Reactive skin often benefits from less frequent application at first, and the main concern, whether rough texture or uneven tone, can help determine the formula.
Before applying a new formula more broadly, the brand recommends a patch test on a small area. Monitor the skin for any reaction. People with sensitive or reactive skin may wish to ask a dermatologist whether an exfoliating acid is appropriate.
For anyone starting an acid serum, the brand advises applying the exfoliant one or two nights per week at first. If the skin remains comfortable, add one more night per week. Pause use if persistent redness or itching develops, and use only the recommended amounts.
Include sun protection in the same routine because exfoliating acids can increase sensitivity to sunlight. The U.S. Food and Drug Administration recommends that alpha hydroxy acid products carry a label advising sunscreen, protective clothing, and limited sun exposure during use and for a week afterward.
Storage also affects product stability. Keep the bottle closed between applications and store it out of direct sunlight and away from excessive heat. Check the listed expiration date, and replace the product if its appearance or scent changes noticeably.
