Skincare for sensitive skin — what it is and what actually helps.

Sensitive skin is one of the most commonly reported skin concerns — studies suggest 50–60% of people describe their skin as sensitive or very sensitive at some point. It is also one of the most frequently misunderstood, because "sensitive" is used to describe both a temporary state that most people experience and a chronic condition that requires a different approach.

The starting point is the same for both: what sensitivity actually is.

What sensitive skin is

Sensitivity is primarily a barrier state, not a skin type. When the barrier is intact — the lipid matrix dense, the acid mantle stable, ceramide levels adequate — the skin can tolerate a wide range of ingredients and environmental conditions without reacting. When the barrier is compromised, that tolerance narrows.

A compromised barrier is more permeable. Ingredients that would not normally penetrate intact skin — fragrances, preservatives, surfactants — reach immune cells in the deeper layers and trigger inflammatory responses. The result is redness, stinging, itching, or the burning sensation that many people recognise as their skin "reacting" to a product.

This means that for many people, sensitivity is not a fixed trait — it is the result of a barrier that has been disrupted, and it can be improved.

What disrupts the barrier and increases sensitivity

Alkaline cleansers. Traditional foaming cleansers with a pH of 8–10 temporarily raise the skin's surface pH with every wash. Skin recovers, but repeated daily disruption gradually reduces barrier resilience — particularly for people already prone to dryness or sensitivity.

Over-exfoliation. Chemical and physical exfoliants work by removing surface layers of the stratum corneum — the outermost barrier. Moderate, infrequent use improves texture. Frequent or high-strength use removes barrier layers faster than the skin can rebuild them, leaving a thin, reactive surface that sensitises to ingredients it previously tolerated.

Multiple actives simultaneously. Introducing several active ingredients at once — retinol, AHAs, vitamin C, salicylic acid — makes it impossible to determine which one is causing a reaction. It also overwhelms the barrier's repair capacity. Sensitive skin requires the opposite approach: one variable at a time, assessed over six to eight weeks.

Fragrance. Fragrance is the most common cause of cosmetic contact sensitisation. The molecules that carry scent are among the most studied allergens in dermatology. For already-reactive skin, fragrance is the first ingredient to eliminate.

What helps

Simplify. The single most reliable intervention for sensitive skin is reducing the number of products and ingredients in contact with the skin. Fewer products means fewer potential triggers, fewer interactions between actives, and fewer opportunities for the barrier to be overwhelmed. A three-step routine with well-tolerated ingredients outperforms a ten-step routine with multiple actives in almost every clinical study of sensitive skin management.

Low-pH, non-foaming cleansing. An oil cleanser or a gentle pH-balanced water cleanser removes surface residue without alkaline disruption. This single change reduces the cumulative pH stress on the barrier with every cleanse.

Barrier-supporting moisturiser. Ceramides, squalane, shea butter, and fatty acids reinforce the lipid matrix. A moisturiser applied consistently after cleansing reduces transepidermal water loss and gives the barrier the lipids it needs to regenerate. The evidence for ceramide-containing moisturisers in sensitive and reactive skin conditions — including eczema and rosacea — is strong.

Fragrance-free formulations. Not "unscented" — products that contain no added fragrance at all. Masking fragrances that neutralise odour still introduce sensitising chemicals.

Time. A compromised barrier takes weeks to recover. Meaningful barrier recovery takes four to eight weeks of consistent, simple care.

What to introduce carefully — and when

Active ingredients are not off-limits for sensitive skin. They require careful introduction on a stable baseline.

Niacinamide is one of the best-tolerated actives for sensitive skin: non-irritating at appropriate concentrations (2–5%), no photosensitivity effects, and it directly builds ceramide synthesis from within — reinforcing the barrier rather than stressing it. A sensible first addition once the barrier is stable.

Retinoids and exfoliating acids should follow, not precede, a stable foundation. On a compromised baseline, these ingredients cause more irritation than benefit.

The Lux & Glo position

The ritual was designed to be suitable for sensitive skin because its formulation principles overlap with sensitive skin management: no fragrance, no unnecessary actives, a cleanser that does not disrupt pH, and a moisturiser that reinforces the lipid matrix with squalane and shea butter.

Sensitive skin does not need a specialised routine. It needs a simple one.
