No, you do not necessarily need to eliminate all active ingredients, but a strategic 'fast' or reduction is often scientifically indicated. When the skin barrier is compromised, evidenced by transepidermal water loss (TEWL) and inflammation, the penetration of potent actives like L-ascorbic acid or retinoids increases significantly, potentially exacerbating irritant contact dermatitis [1]. However, certain active ingredients are actually restorative. Specifically, humectants like glycerin and barrier-repairing lipids like ceramides and cholesterol are essential for accelerating the recovery of the stratum corneum [2].
The decision to cease an active depends on its mechanism. Pro-inflammatory actives that rely on a low pH or cellular turnover (like AHAs or high-strength Vitamin A) should be paused to allow the inflammatory cascade to subside [3]. Conversely, soothing actives such as niacinamide (at concentrations below 5%) and panthenol (Pro-vitamin B5) can help stabilise the skin's immune response and enhance the synthesis of natural moisturising factors (NMF) during the sensitivity phase [4].
Skin sensitivity is frequently a manifestation of a disrupted epidermal barrier, where the 'bricks and mortar' structure of corneocytes and lipid lamellae is compromised. This increased permeability allows irritants to reach deeper layers of the epidermis, triggering the release of cytokines and activating the cutaneous nervous system [1][5]. Scientific management focuses on 'restorative biocompatibility'—providing the skin with the components it needs to self-repair while removing extrinsic stressors.
In the Australian climate, high UV indices can further aggravate sensitised skin through photo-inflammation. Therefore, while exfoliating acids may be paused, the most critical 'active' that must never be eliminated is a broad-spectrum sunscreen. Modern formulations often include anti-inflammatory agents like bisabolol or allantoin to protect the skin without causing further stinging or erythema during periods of reactivity [2][6].
For those navigating periods of sensitivity, integrating ingredients that support the microbiome and barrier resilience can be more beneficial than a total elimination of all topicals. If you are looking to maintain hydration without irritation, our Balance Biome Crème was formulated with Bifida Ferment Lysate and Niacinamide to work with your skin’s natural defences rather than over them. Paired with a non-stripping cleanser like Surface Calm, which features a specialised ceramide complex, this approach ensures the skin remains nourished while its protective lipid layer is restored.
FAQ
Which specific actives should I stop using immediately?
You should immediately pause the use of high-strength retinoids (Tretinoin, Retinol), Alpha-Hydroxy Acids (Glycolic, Lactic), and high-concentration Vitamin C (L-ascorbic acid). These ingredients either lower the skin's pH significantly or accelerate cell turnover, which can further thin the stratum corneum and aggravate sensory nerve endings [3][7].
Are there any 'safe' actives to use during a flare-up?
Yes, ingredients focused on hydration and barrier support are beneficial. Niacinamide (Vitamin B3) at 2-5% helps stimulate ceramide production, while Madecassoside (derived from Centella Asiatica) has clinical evidence for reducing redness and promoting wound healing [4][8]. Hyaluronic acid and panthenol are also excellent for maintaining hydration without causing irritation [2].
How long should I wait before reintroducing potent actives?
Typically, the skin requires 14 to 28 days—the length of a full desquamation cycle—to significantly repair its barrier function. You should wait until all symptoms of stinging, redness, and dryness have subsided for at least 72 hours before reintroducing one active at a time, starting with lower concentrations or less frequent applications (e.g., twice weekly) [5][9].
