Identifying Your Skin Concerns

Hyperpigmentation

Hyperpigmentation is characterised by brown patches that are darker in colour than the surrounding skin. It is most commonly seen as freckles, age spots, and post-inflammatory hyperpigmentation. It is characterised by:

  • Uneven skin tone
  • Dark spots after a break-out
  • Symmetrical dark brown patches on top lip, orbital bone, and forehead

The Recommendation

Skin experiencing Hyperpigmentation needs Antioxidants and brightening actives to visibly even tone, in addition to SPF to protect against further damage. This skincare Ritual features ingredients that brighten the complexion’s appearance, support healthy cell renewal, and protect against solar damage—for a more even-looking complexion.

Fine Lines and Wrinkles

The Definition

Fine lines and wrinkles refer to the loss of collagen and elastin, which occur as a result of ageing and sun exposure. Fine lines and wrinkles are characterised by:

  • Facial sagging
  • Fine lines on the forehead
  • Cross-hatching lines around mouth and eyes

The Recommendation 

Skin experiencing fine lines and wrinkles needs Vitamins and firming actives to support the skin’s architecture and to preserve collagen, as well as SPF to protect against solar-induced damage. This skincare Ritual features ingredients that visibly improve skin firmness, support collagen, and maintain skin’s innate repair capacity for a firmer, more defined appearing profile

Sensitivity

The Definition

Sensitivity often presents as red, irritated skin, which is highly reactive to heat, active ingredients and the sun. Sensitivity is characterised by:

  • Skin that appears red and irritated
  • Low tolerance to active ingredients
  • Skin that flushes easily

The Recommendation 

Skin experiencing sensitivity requires calming and nourishing actives to support healthy barrier function and soothes the skin. This skincare Ritual features ingredients that reduce the appearance of redness and support healthy barrier function for a calmer, clearer complexion.

Congestion and Oily

The Definition

Congestion can occur when pores become clogged, or as a result of producing excessive sebum. It is characterised by:

  • Raised bumps with a red or white head
  • Small bumps under the skin mouth and eyes
  • Red, inflamed cysts

The Recommendation

Skin experiencing congestion requires resurfacing actives which support healthy pH and promote cell turnover. This skincare Ritual features ingredients that refine tone and texture, while balancing sebum production and supporting a healthy skin microbiome for a clearer, more refined complexion.

Dryness

The Definition

Dryness occurs when the skin is lacking crucial lipids required for healthy skin. It is characterised by:

  • Dry, scaly skin
  • Small patches of flaky skin
  • Tight sensation after cleansing or showering

The Recommendation 

Skin experiencing dryness requires intense nourishment to protect against moisture loss and to prevent damage from environmental aggressors. This skincare Ritual features ingredients that lock in moisture and strengthen the skin’s barrier to alleviate dry, flaky skin for a smoother complexion.

Dehydration

The Definition

Dehydration occurs when the skin is lacking water, resulting in loss of moisture. It is characterised by:

  • Very fine lines all over the skin
  • A tight sensation on the skin
  • Dull appearance

The Recommendation

Skin experiencing dehydration requires water-binding actives to increase moisture and prevent damage from environmental aggressors. This skincare Ritual features ingredients that amplify hydration for a more radiant complexion.
