How should I apply it, and do I rinse it off?

At the serum stage, spread an appropriate amount evenly over your face, then gently pat to help it absorb. This is a leave-on step, so there is no need to rinse.

Which skin types is it marketed for?

Retailer guidance lists it for all skin types and mature skin. The official product page does not provide its own skin-type classification.

Does the formula contain aromatic plant oils?

Yes. The ingredient declaration includes Mexican juniper, Damask rose flower, patchouli and vetiver root oils. It is not essential-oil-free, and the available evidence does not support a fragrance-free claim.

PRODUCT DETAILS

Hello, firm-feeling moisture. This facial serum is made for days when your skin could use a little more cushion. It delivers firm-feeling moisture while supporting a smoother-looking finish.

Texture is part of its appeal. The firm, elastic-feeling serum wraps smoothly over your skin and leaves a substantial moisturized finish. Despite that cushioned feel, it’s lightweight rather than heavy, giving you a smooth wrap with comfortable moisture.

The formula includes collagen extract and oat peptide. Glycerin helps skin hold water and feel softer, while panthenol supports moisture and comfort. Adenosine adds smoother-looking care for the appearance of fine lines. Together, they offer moisture and smoother-looking care in one serum step.

If aromatic plant oils matter to your routine, the formula includes Damask rose flower oil, patchouli oil, Mexican juniper oil and vetiver root oil.
